https://timewell.jp/en/columns Latest TIMEWELL articles on AI adoption, digital transformation, export compliance, and community operations en Sun, 06 Sep 2026 00:00:00 GMT https://timewell.jp/icon.png https://timewell.jp/en https://timewell.jp/en/columns/ai-business-guidelines-1-2-changes-2026 https://timewell.jp/en/columns/ai-business-guidelines-1-2-changes-2026 Japan's AI Business Operator Guidelines moved to version 1.2. Read next to version 1.1, the update is less about new rules than about settling what words mean. Here are the seven agenda items behind the revision, and where the document sits relative to the AI Promotion Act and the AI Basic Plan, checked line by line against the primary sources. Sun, 06 Sep 2026 00:00:00 GMT Ryuta Hamamoto zerock https://timewell.jp/en/columns/appi-article-28-llm-api-cross-border-2026 https://timewell.jp/en/columns/appi-article-28-llm-api-cross-border-2026 If you put a prompt into an overseas LLM API, is that a cross-border provision under Article 28 of Japan's personal data protection act? The Commission's generative AI alert contains no reference to Article 28, to "a third party in a foreign country" or to cross-border transfers. Here is what the statute, Enforcement Rules 16, 17 and 18, the Guidelines and Q&A items Q7-53 and Q12-4 actually say. Sun, 06 Sep 2026 00:00:00 GMT Ryuta Hamamoto zerock https://timewell.jp/en/columns/azure-openai-data-zone-japan-2026 https://timewell.jp/en/columns/azure-openai-data-zone-japan-2026 "We chose the Data Zone, so we are inside Japan" does not match what the official documentation actually says. Data at rest stays in the designated geography, but inference is described as "any Asia Pacific nation", which is not Japan. Here is what japaneast really offers, read from primary sources on 6 September 2026. Sun, 06 Sep 2026 00:00:00 GMT Ryuta Hamamoto zerock https://timewell.jp/en/columns/digital-agency-generative-ai-procurement-guideline-2026 https://timewell.jp/en/columns/digital-agency-generative-ai-procurement-guideline-2026 Japan's Digital Agency put DS-920 into force on September 1, 2026. Read all 64 pages and two things stand out. The government never uses the word "region" to pin down where data sits, and its procurement checklist treats being able to swap the model out later as a baseline requirement rather than a bonus. Here is what a private buyer can lift from it. Sun, 06 Sep 2026 00:00:00 GMT Ryuta Hamamoto zerock https://timewell.jp/en/columns/financial-institutions-generative-ai-data-location-2026 https://timewell.jp/en/columns/financial-institutions-generative-ai-data-location-2026 When a Japanese financial institution runs generative AI, what do the public documents actually require about where the data sits? The FISC Security Guidelines themselves are a paid publication that outsiders cannot verify, so this piece uses only free sources: the FSA's AI Discussion Paper, FISC's own public reports, and the privacy regulator's Q&A. It separates knowing your data's location from confining it, and lists what belongs in the contract. Sun, 06 Sep 2026 00:00:00 GMT Ryuta Hamamoto zerock https://timewell.jp/en/columns/foreign-government-access-cloud-act-china-gdpr-2026 https://timewell.jp/en/columns/foreign-government-access-cloud-act-china-gdpr-2026 US law says disclose "regardless of whether" the data sits inside or outside the country. GDPR Article 48 says a foreign order is enforceable only through an international agreement. Japan's cabinet has stated that the "based on laws" exemption covers Japanese law only. Here is what the texts actually say, and where we stand. Sun, 06 Sep 2026 00:00:00 GMT Ryuta Hamamoto zerock https://timewell.jp/en/columns/ismap-data-residency-cloud-2026 https://timewell.jp/en/columns/ismap-data-residency-cloud-2026 The service passed Japanese government procurement, so the data must be in Japan. Read the actual program documents and that inference falls apart. Across all 45 pages of the ISMAP control standard, the words for "Japan", "outside the country" and "cross-border" never appear once, and the clauses that touch location go no further than notifying customers which countries may hold their data and assessing the risk of foreign law reaching it. Here are the clause numbers. Sun, 06 Sep 2026 00:00:00 GMT Ryuta Hamamoto zerock https://timewell.jp/en/columns/medical-information-guideline-7-cloud-ai-2026 https://timewell.jp/en/columns/medical-information-guideline-7-cloud-ai-2026 Japan's Ministry of Health, Labour and Welfare has moved its Guidelines for the Safety Management of Medical Information Systems to version 7.0. A new volume for maintenance contractors, an explicit push toward cloud services, and a storage clause written around the reach of domestic law rather than geography. I also ran a full-text search across all 169 pages and found no mention of generative AI anywhere. Sun, 06 Sep 2026 00:00:00 GMT Ryuta Hamamoto zerock https://timewell.jp/en/columns/vertex-ai-tokyo-region-data-residency-2026 https://timewell.jp/en/columns/vertex-ai-tokyo-region-data-residency-2026 Seven Google models answer at the Tokyo endpoint (asia-northeast1). Eight entries are committed to ML processing inside Japan. Those two lists live on different pages, in different tables, and they do not match. Here is what the official documentation actually says about endpoints, context length and jurisdiction. Sun, 06 Sep 2026 00:00:00 GMT Ryuta Hamamoto zerock https://timewell.jp/en/columns/llm-japan-region-availability-guide-2026 https://timewell.jp/en/columns/llm-japan-region-availability-guide-2026 "Available in the Tokyo region" and "processed only in the Tokyo region" are two different claims. Read the official documentation from AWS, Microsoft and Google and a pattern shows up: the newer the model, the less likely it can stay inside Japan. Here is what the docs actually say, and which rules genuinely require domestic processing. Sat, 05 Sep 2026 00:00:00 GMT Ryuta Hamamoto zerock https://timewell.jp/en/columns/kokotajlo-doac-interview-analysis https://timewell.jp/en/columns/kokotajlo-doac-interview-analysis Former OpenAI researcher Daniel Kokotajlo appeared on The Diary of a CEO and said there is a 70% chance things go horribly wrong. That figure is not the same as human extinction. Here is what it actually refers to, what AI 2027 and AI 2040 Plan A each claim, from primary sources, and what practically remains for companies that use AI. Sat, 29 Aug 2026 00:00:00 GMT Ryuta Hamamoto ai-security https://timewell.jp/en/columns/alayasiki-domestic-ai-defense-system https://timewell.jp/en/columns/alayasiki-domestic-ai-defense-system On August 27, 2026, Skygate Technologies announced Alayasiki, a domestically developed AI defense system for Japan. It claims conformance with US MIL-STD and NATO APP/STANAG/ADatP, and operation in air-gapped environments. Here is what the system does, why standards conformance and data sovereignty are argued together, and what "switch-off risk" means — drawn from the press release and Japanese government materials. Sat, 29 Aug 2026 00:00:00 GMT Ryuta Hamamoto trafeed https://timewell.jp/en/columns/cia-moscow-visit-2026-grey-zone-risk https://timewell.jp/en/columns/cia-moscow-visit-2026-grey-zone-risk On 25 August 2026 the CIA director flew to Moscow unannounced. The reported purpose was a warning not to attack NATO. But what US intelligence is said to be worried about is not conventional war, and that distinction changes what companies should do about it. Thu, 27 Aug 2026 00:00:00 GMT Ryuta Hamamoto trafeed https://timewell.jp/en/columns/hormuz-strait-transit-data-analysis https://timewell.jp/en/columns/hormuz-strait-transit-data-analysis I aggregated 512 days of daily transit counts for the Strait of Hormuz. Before the closure, 84.8 vessels a day; after, 7.1. The collapse took three days. And the partial recovery that appeared in June had disappeared again by August. Thu, 27 Aug 2026 00:00:00 GMT Ryuta Hamamoto trafeed https://timewell.jp/en/columns/jcg-unmanned-procurement-all-contracts-analysis https://timewell.jp/en/columns/jcg-unmanned-procurement-all-contracts-analysis I pulled every unmanned aircraft and unmanned vessel contract the Japan Coast Guard awarded between FY2023 and FY2026 from the bid result PDFs. Nine contracts, ¥410.8 million. The range between largest and smallest is 126x, and where one bidder showed up, the award ratio pinned to the ceiling. Thu, 27 Aug 2026 00:00:00 GMT Ryuta Hamamoto trafeed https://timewell.jp/en/columns/meti-export-control-violations-6years-analysis https://timewell.jp/en/columns/meti-export-control-violations-6years-analysis Japan's METI publishes an annual analysis of export control violations, one PDF per year, with nobody stitching them together. I pulled all six and counted. The share found by customs audits roughly tripled in three years, and the leading cause was not what I expected. Thu, 27 Aug 2026 00:00:00 GMT Ryuta Hamamoto trafeed https://timewell.jp/en/columns/taiwan-japan-export-control-entity-list-comparison https://timewell.jp/en/columns/taiwan-japan-export-control-entity-list-comparison I pulled Taiwan's daily-updated export entity control list and Japan's End User List in full and compared them. 11,664 entries against 835, roughly 14x apart. But this is not a question of which is stricter. The two countries build lists on fundamentally different premises. Thu, 27 Aug 2026 00:00:00 GMT Ryuta Hamamoto trafeed https://timewell.jp/en/columns/yc-summer-2026-batch-analysis https://timewell.jp/en/columns/yc-summer-2026-batch-analysis I went through all 236 companies in Y Combinator's Summer 2026 batch using the public directory data. Median team size is two people, industrials make up 23%, and a cluster of companies sells to AI agents rather than to humans. Here is what is happening and what it suggests for anyone building something, with links to every company. Wed, 26 Aug 2026 00:00:00 GMT Ryuta Hamamoto techtrend https://timewell.jp/en/columns/digital-agency-administrative-procedures-mcp https://timewell.jp/en/columns/digital-agency-administrative-procedures-mcp Japan's Digital Agency has released an MCP server that makes its administrative procedures survey (about 75,000 records) queryable in natural language. The interesting part is not the release but the architecture: the AI never touches raw data to compute. Here is what MCP is, what problem this design solves, and what changes once agents get involved. Tue, 25 Aug 2026 00:00:00 GMT Ryuta Hamamoto techtrend https://timewell.jp/en/columns/japan-growth-strategy-2026-17-fields-62-technologies https://timewell.jp/en/columns/japan-growth-strategy-2026-17-fields-62-technologies Japan's Cabinet approved the Growth Strategy on 21 July 2026. I read all 399 pages of the official documents: the full list of 17 strategic sectors and 62 major products and technologies, how to read the ¥370 trillion figure correctly, and the budget rules that quietly changed. Tue, 25 Aug 2026 00:00:00 GMT Ryuta Hamamoto trafeed https://timewell.jp/en/columns/jcg-unmanned-vessel-albatross-yanmar-automation https://timewell.jp/en/columns/jcg-unmanned-vessel-albatross-yanmar-automation Yanmar has automated a vessel from departure through offshore navigation to docking, a first in Japan, and is testing it on a Japan Coast Guard unmanned boat. I traced what that boat is for, the two contracts that produced it, and the technology underneath, using the Coast Guard's own disclosure records. Tue, 25 Aug 2026 00:00:00 GMT Ryuta Hamamoto trafeed https://timewell.jp/en/columns/fertility-gap-japan-ideal-vs-actual-children https://timewell.jp/en/columns/fertility-gap-japan-ideal-vs-actual-children Japan sits in the darkest red on the global fertility gap map. But that map measures the distance between desired and actual children, not low fertility itself. Japanese couples name 2.25 as ideal; the fertility rate is 1.14. They are not choosing against children. They are constrained, and constraints are design problems. Mon, 24 Aug 2026 00:00:00 GMT Ryuta Hamamoto consulting https://timewell.jp/en/columns/bis-black-mass-tungsten-export-restriction-2026 https://timewell.jp/en/columns/bis-black-mass-tungsten-export-restriction-2026 On 6 August 2026 BIS ordered sellers of lithium-ion black mass and tungsten waste and scrap to allocate 100% of monthly sales to U.S. persons. The authority is not the EAR but the Defense Production Act. Here is what it means that export control is now being used to keep resources at home. Mon, 24 Aug 2026 00:00:00 GMT Ryuta Hamamoto trafeed https://timewell.jp/en/columns/japan-aerospace-self-defense-force-2026-space-domain https://timewell.jp/en/columns/japan-aerospace-self-defense-force-2026-space-domain Japan's amended Defense Ministry Establishment Act passed in June 2026. The Air Self-Defense Force will be renamed the Aerospace Self-Defense Force, its first name change in 72 years. What was decided, why space, and what Japan's own defense ministry documents say about how far behind the country is. Mon, 24 Aug 2026 00:00:00 GMT Ryuta Hamamoto trafeed https://timewell.jp/en/columns/pax-silica-silicon-highway-supply-chain-provenance https://timewell.jp/en/columns/pax-silica-silicon-highway-supply-chain-provenance Pax Silica grew to 24 signatories at its second summit in June 2026. The Silicon Highway, backed by up to $50 million, would move trusted cargo faster using cryptographic verification and pre-approval. Export control is shifting from screening names, to tracing ownership, to proving provenance. Mon, 24 Aug 2026 00:00:00 GMT Ryuta Hamamoto trafeed https://timewell.jp/en/columns/technology-leakage-sentencing-japan-korea-cxmt https://timewell.jp/en/columns/technology-leakage-sentencing-japan-korea-cxmt Korean courts handed down six years four months and seven years for leaking Samsung DRAM process technology to a Chinese manufacturer. Against a development cost of 1.6 trillion won, is that proportionate? A look at Korean sentencing, Japan's far lower ceiling, and why criminal law can never protect your technology. Mon, 24 Aug 2026 00:00:00 GMT Ryuta Hamamoto trafeed https://timewell.jp/en/columns/aliexpress-webaudio-fingerprinting https://timewell.jp/en/columns/aliexpress-webaudio-fingerprinting Open AliExpress and the music on your phone stops. Chasing that symptom led to a device-identification routine running through the Web Audio API. No microphone is involved. Here is the mechanism from primary sources, and the countermeasures that genuinely work, for individuals and for IT departments. Sun, 23 Aug 2026 00:00:00 GMT Ryuta Hamamoto ai-security https://timewell.jp/en/columns/daitan-investment-promotion-tax-guide https://timewell.jp/en/columns/daitan-investment-promotion-tax-guide On July 31, 2026, Japan opened applications for a new capital investment tax incentive covering essentially every industry. You can elect immediate expensing or a 7% tax credit on an asset-by-asset basis, and buildings are included. Here are the two numerical thresholds, the application flow, and the traps that quietly disqualify a plan, drawn from primary sources. Sun, 23 Aug 2026 00:00:00 GMT Ryuta Hamamoto consulting https://timewell.jp/en/columns/kakenhi-budget-request-2027-doubling https://timewell.jp/en/columns/kakenhi-budget-request-2027-doubling Japan's education ministry is reported to be seeking roughly double the current KAKENHI budget for FY2027, at 455.2 billion yen, together with converting the whole scheme to multi-year funds. This is a request, not a decision. Here is what would grow, and whether the widely held belief that KAKENHI was slashed holds up against the published statistics. Sun, 23 Aug 2026 00:00:00 GMT Ryuta Hamamoto consulting https://timewell.jp/en/columns/startup-secondary-share-transaction-guide https://timewell.jp/en/columns/startup-secondary-share-transaction-guide Smartround Securities has completed registration as a Type I financial instruments business, clearing the way to handle secondary transactions in private company shares. Here is what a secondary transaction actually is, why the market never developed in Japan, what the 2024 amendment to the Financial Instruments and Exchange Act changed, and what founders should decide before the first request lands on their desk. Sun, 23 Aug 2026 00:00:00 GMT Ryuta Hamamoto consulting https://timewell.jp/en/columns/strategic-technology-rd-tax-credit-guide https://timewell.jp/en/columns/strategic-technology-rd-tax-credit-guide Japan's amended Industrial Technology Enhancement Act (Act No. 41 of 2026) adds a 40% R&D tax credit, rising to 50% for joint research with certified institutions. But the credit is capped at 10% of corporate tax, eligibility requires confirmation that commercialization is expected early, and the law's effective date is still awaiting a cabinet order. Here is what the statute and the tax outline actually say. Sun, 23 Aug 2026 00:00:00 GMT Ryuta Hamamoto consulting https://timewell.jp/en/columns/china-counter-sanctions-and-drone-export-control https://timewell.jp/en/columns/china-counter-sanctions-and-drone-export-control On August 5, 2026, China's Ministry of Commerce announced countermeasures against seven US entities and tightened export controls on drone-related dual-use items headed to the United States, on the same day. The countermeasures bind "organizations and individuals within China," which means Chinese subsidiaries of Japanese companies are directly covered. Here are the four different Chinese lists, where Japan already stands, and how to position a business that trades with both sides. Fri, 21 Aug 2026 00:00:00 GMT Ryuta Hamamoto trafeed https://timewell.jp/en/columns/gallium-germanium-china-dependence-alternatives https://timewell.jp/en/columns/gallium-germanium-china-dependence-alternatives Three years on from China's gallium and germanium export controls, prices keep climbing and rare earth magnet shipments to Japan fell to 111 tonnes in July. Dependence has barely shifted, and the reason is structural: gallium is not mined on its own, it is a byproduct. Working from USGS primary statistics, here is the shape of the dependence, where alternative supply actually stands, and what a company can realistically do. Fri, 21 Aug 2026 00:00:00 GMT Ryuta Hamamoto trafeed https://timewell.jp/en/columns/humanoid-robot-fcc-covered-list https://timewell.jp/en/columns/humanoid-robot-fcc-covered-list On July 28, 2026, the FCC added foreign-produced advanced robotic devices to its Covered List. Chinese robots are getting the coverage, but the determination says "regardless of the nationality of origin" — which puts Japanese-made robots in the same bucket. Here is what is actually prohibited, what is not, the two exemption routes, and what companies handling robots should check. Fri, 21 Aug 2026 00:00:00 GMT Ryuta Hamamoto trafeed https://timewell.jp/en/columns/remote-access-export-control-gap https://timewell.jp/en/columns/remote-access-export-control-gap You can stop the chip from leaving the country, but you cannot stop someone from using it over a network connection. This piece traces where that difference comes from, working from the text of the EAR, BIS's own advisory opinions, and the Japanese Foreign Exchange and Foreign Trade Act. It covers what the RASA bill actually says, whether Japan has the same gap, and what to check in practice. Fri, 21 Aug 2026 00:00:00 GMT Ryuta Hamamoto trafeed https://timewell.jp/en/columns/sakura-internet-unauthorized-access-2026-lessons https://timewell.jp/en/columns/sakura-internet-unauthorized-access-2026-lessons In August 2026, Sakura Internet disclosed unauthorized access to its hosting environment and later to its sales management system. This is not a piece about what the company did wrong. It walks through why provider-side intrusions happen, what legal duties stay with the customer, and how to read the scope of an ISMAP registration before you rely on it. Wed, 19 Aug 2026 00:00:00 GMT Ryuta Hamamoto ai-security https://timewell.jp/en/columns/meti-economic-security-case-studies https://timewell.jp/en/columns/meti-economic-security-case-studies Japan's Ministry of Economy, Trade and Industry has published a collection of concrete corporate case studies on economic security. Where the guidelines said what companies should do, this one shows what other companies actually did, across 11 cases. From a plant that stopped for a day to a firm that built up inventory and won investor confidence for it. Here is the behavior-change framework it uses, and what financial institutions say they are really looking at. Tue, 18 Aug 2026 00:00:00 GMT Ryuta Hamamoto trafeed https://timewell.jp/en/columns/toshiba-prodrone-interceptor-drone https://timewell.jp/en/columns/toshiba-prodrone-interceptor-drone Toshiba and Prodrone announced a technical partnership on a domestically produced interceptor drone. The line worth reading twice is not about the aircraft. It is this: "We will build a supply chain based on domestic parts and establish a stable supply structure." Here is why a defense announcement spends a sentence on procurement, and what it means for anyone who supplies parts. Tue, 18 Aug 2026 00:00:00 GMT Ryuta Hamamoto trafeed https://timewell.jp/en/columns/apple-china-memory-us-pressure-2026 https://timewell.jp/en/columns/apple-china-memory-us-pressure-2026 In August 2026, Commerce Secretary Lutnick said the administration opposes Apple sourcing Chinese memory. Here are the Senate and House letters, where CXMT and YMTC actually sit in US regulation, and what Section 5949 and the pending FAR rule mean for component suppliers in Japan and elsewhere. Sat, 15 Aug 2026 00:00:00 GMT Ryuta Hamamoto trafeed https://timewell.jp/en/columns/foreign-interference-prevention-law-japan https://timewell.jp/en/columns/foreign-interference-prevention-law-japan On August 5, 2026, the LDP's Intelligence Strategy Headquarters released its second set of recommendations on strengthening Japan's "information defense capability." Here is what the three pillars of deterrence, collection, and oversight actually contain, read against the statutory text. Sat, 15 Aug 2026 00:00:00 GMT Ryuta Hamamoto trafeed https://timewell.jp/en/columns/ai-model-silent-downgrade-trust-open-weights https://timewell.jp/en/columns/ai-model-silent-downgrade-trust-open-weights In June 2026 Anthropic routed some Fable 5 requests to Opus 4.8. Safety was the stated reason. Buying one SKU and receiving another is still a procurement problem. That is why I side with Grok, some Chinese open-weight labs, and NVIDIA Nemotron. Fri, 14 Aug 2026 00:00:00 GMT Ryuta Hamamoto techtrend https://timewell.jp/en/columns/whitehouse-transshipment-scam-japan-2026 https://timewell.jp/en/columns/whitehouse-transshipment-scam-japan-2026 On 13 August 2026 the White House published a 25-page report on illegal transshipment. Headlines led with $75 billion, 450,000 jobs, and Japan. The primary text puts Japan in Tier 1 for the scale of legitimate trade, not because a scheme was pinned to a Japanese city. This column reads the estimates and the enforcement that follows. Fri, 14 Aug 2026 00:00:00 GMT Ryuta Hamamoto trafeed https://timewell.jp/en/columns/glassworm-invisible-unicode-supply-chain https://timewell.jp/en/columns/glassworm-invisible-unicode-supply-chain GlassWorm hides executable code inside Unicode characters that render as nothing at all. It spread through VS Code extensions, self-propagating with stolen credentials, and reached 35,800 installs. Here is why the characters are invisible, where you step on them, and how to defend once visual review no longer works. Thu, 13 Aug 2026 00:00:00 GMT Ryuta Hamamoto ai-security https://timewell.jp/en/columns/ai-text-watermark-how-it-works https://timewell.jp/en/columns/ai-text-watermark-how-it-works In August 2026, Claude began weaving an invisible watermark into generated text. The trigger is Article 50 of the EU AI Act. This piece walks through how token-level watermarks work, why ChatGPT and Grok have not shipped the same thing for text, and where the mark quietly fails. Thu, 13 Aug 2026 00:00:00 GMT Ryuta Hamamoto techtrend https://timewell.jp/en/columns/spacexai-grok46-build-bot-three-days https://timewell.jp/en/columns/spacexai-grok46-build-bot-three-days Grok Bot on 11 August 2026, Grok 4.6 on the 12th. SpaceXAI shipped an agent product and a new model on consecutive days. Read the published benchmarks honestly and it leads on 3 of 10 rows — the real story sits elsewhere. Musk’s remarks to staff, the price structure, and the gap with the Chinese labs. Thu, 13 Aug 2026 00:00:00 GMT Ryuta Hamamoto techtrend https://timewell.jp/en/columns/japan-positioning-sovereignty-michibiki-h3 https://timewell.jp/en/columns/japan-positioning-sovereignty-michibiki-h3 On 11 August 2026 an H3 rocket placed Michibiki No. 7 into its planned orbit. The seven-satellite constellation is not complete: No. 5 was lost, and the target is now FY2031. What sustained positioning means, what six centimetres changes, and why 15.3% energy and 37% food self-sufficiency belong in the same conversation. Thu, 13 Aug 2026 00:00:00 GMT Ryuta Hamamoto trafeed https://timewell.jp/en/columns/agent-engineering-harness-design https://timewell.jp/en/columns/agent-engineering-harness-design Anthropic analysed about 400,000 sessions and found people still make about 70% of the planning decisions, while AI makes about 80% of the execution decisions. People with deeper expertise produce five times the output per session. The length of task you can leave alone keeps doubling, and the gap comes from the environment around the model, not the model itself. Thu, 13 Aug 2026 00:00:00 GMT Ryuta Hamamoto warp https://timewell.jp/en/columns/fde-vs-ai-accompaniment https://timewell.jp/en/columns/fde-vs-ai-accompaniment MIT NANDA's research finds that against an estimated 30 to 40 billion dollars spent on generative AI, 95% of organisations have not seen a measurable return. Putting an engineer on the floor as an FDE, and the AI accompaniment Japan talks about a lot, look similar. Follow what is being sold, who owns the work, and whether anything is written back into the system, and they are different jobs. Thu, 13 Aug 2026 00:00:00 GMT Ryuta Hamamoto warp https://timewell.jp/en/columns/cloudflare-os-open-source-strategy https://timewell.jp/en/columns/cloudflare-os-open-source-strategy On 5 August 2026 Cloudflare open-sourced the AI agent platform it had been running internally. Agents that start with zero access, Gatekeepers that hold credentials so agents never touch them, and an observation log of everything an agent reads. The design ideas are worth taking today. The claim that open source means freedom from vendor dependence deserves a closer look. Thu, 13 Aug 2026 00:00:00 GMT Ryuta Hamamoto zerock https://timewell.jp/en/columns/china-detention-japanese-nationals-export-control-2026 https://timewell.jp/en/columns/china-detention-japanese-nationals-export-control-2026 Several Japanese nationals have been reported detained in China, in connection with suspicion relating to export controls on dual-use items including rare earths. Starting from the premise that detention is not a finding of guilt, this sets out the gap most companies have — watching their own country's export controls but not the counterparty country's — and what to decide in advance. Wed, 12 Aug 2026 00:00:00 GMT Ryuta Hamamoto trafeed
