Hello, this is Ryuta Hamamoto from TIMEWELL.
Prime Minister Sanae Takaichi posted about the amended Industrial Technology Enhancement Act on her X account. It opens with a reading of the times.
We have entered a new era that might be called the "convergence of science and business," in which the results of basic science are rapidly implemented in society and lead to new businesses.
Around the world, leading companies are competing to invest enormous sums in advanced technology, and universities are growing substantially as the recipients of that investment.
The underlying point is simple enough. Getting basic research into a product used to take ten or twenty years. Now an algorithm from a lab becomes a multi-trillion-yen industry within a few years. The lag between research and business is disappearing.
On that reading, the post continues:
The law for Japan to win in this era and fundamentally strengthen support for strategic technologies such as AI and quantum is the amended Industrial Technology Enhancement Act, enacted in the recent Diet session.
Through this law, Japan's R&D tax credit gains a 40% rate, rising to 50% where conditions are met. The statute is Act No. 41 of 2026, enacted June 12 and promulgated June 19, 2026.1
Given that the current general rate runs roughly 8.5% to 14%, that is a different order of magnitude. But reading the statute and the tax outline, there is a good deal the headline number will not tell you. The cap, an extra gate on eligibility, and the fact that the effective date is not yet set.
The short version
- The statute is Act No. 41 of 2026, enacted June 12, promulgated June 19. Distinct from the bold investment tax measure (Act No. 29 of 2026)
- The effective date is "a date set by cabinet order within one year of promulgation." Still pending
- The law creates: cabinet-order designation of priority industrial technologies, certification of priority R&D plans, certification of joint R&D institutions, and a special rule on patents from commissioned research
- The credit is 40%, or 50% for research conducted jointly with or commissioned to a certified joint R&D institution
- The cap is 10% of corporate tax for the period. This is what determines the real number
- Easily missed: eligibility is limited to research confirmed as one where early commercialization is expected
- Carryforward runs three years, but only where R&D spending in that year exceeds the prior period
- Certification deadline is March 31, 2029; the application period is five years from certification
Two laws, easily confused
I recently wrote about the bold investment promotion tax measure. That came from amendments to the Industrial Competitiveness Enhancement Act (Act No. 29 of 2026). This is the Industrial Technology Enhancement Act (Act No. 41 of 2026) — a different law.
The names are similar; the aims are not.
| Act No. 29 of 2026 | Act No. 41 of 2026 | |
|---|---|---|
| Amends | Industrial Competitiveness Enhancement Act etc. | Industrial Technology Enhancement Act |
| Main tax measure | Bold investment promotion | New R&D credit |
| Covered spending | Capital investment (machinery, buildings, software) | Research expenses |
| Enacted | May 29, 2026 | June 12, 2026 |
| Promulgated | June 5, 2026 | June 19, 2026 |
Buying equipment is No. 29; doing research is No. 41. Plenty of companies will sit in both.
What the law creates
From the House of Councillors bill summary:1
1. Designation of priority industrial technologies
Where it is found necessary to intensively promote research and development on industrial technology in order to strengthen Japan's industrial technological capabilities, the technology shall be designated as a priority industrial technology by cabinet order
The designation is by cabinet order. Which technologies qualify is not written into the statute itself.
The expected areas appear parenthetically in the Ministry of Finance tax outline:2
AI and advanced robotics, quantum, semiconductors and communications, bio and healthcare, fusion energy, space
Those six. The outline labels them "priority industrial technology (provisional name)," so formal designation awaits the cabinet order.
2. Certification of priority R&D plans
Businesses submit an R&D plan and receive certification. That certification is the gateway to the tax measure. NEDO may provide advice on research and development at the request of certified businesses.
3. Certification of priority industrial technology joint R&D institutions
The counterpart certification, for universities and research institutions. Reaching 50% requires partnering with a certified institution (below). NEDO advice provisions apply here too.
4. Special rule on patents from commissioned research
Where patents arising from state-commissioned research on priority industrial technologies are vested in the contractor, and the state seeks to have them licensed to third parties, the summary says:
the state shall make such a request indicating that, because the patent right relates to a priority industrial technology, it is particularly necessary to promote its utilization
An adjustment to Japan's Bayh-Dole arrangements. Aimed at patents sitting unused.
5. Effective date
This one matters.
This Act shall come into effect on a date to be specified by cabinet order within a period not exceeding one year from the date of promulgation
The effective date is not set. Promulgation was June 19, 2026, so it falls somewhere before June 18, 2027 at the latest. Certification is described as starting in FY2027, but the day the scheme begins is itself waiting on a cabinet order.

How the tax measure works
The Prime Minister's post puts it this way:
First, based on the amended act, we have fundamentally strengthened the R&D tax credit.
Companies that take on research and development in "strategic technology areas" such as AI and quantum will be able to receive an unprecedentedly high credit of up to 50% of their research expenses. Certification under the tax measure is scheduled to begin in FY2027.
"Up to 50%" and "unprecedented." Here is what the mechanism actually is, from the Ministry of Finance FY2026 tax reform outline.2
The R&D tax credit in general
A share of research expenses comes straight off corporate tax — not off income, off tax. That is why it bites hard.
The current general regime sets the rate by how much R&D spending grew year on year, running roughly 8.5% to 14%. From fiscal years beginning on or after April 1, 2027, the formula is revised with a ceiling of 14% (10% as the base).
The new bracket
The outline reads:
a tax credit of 40% of the amount of priority industrial technology research expenses (50% in the case of special priority industrial technology research expenses). Provided that the credit shall be capped at 10% of corporate tax for the period, and any excess over the credit limit may be carried forward for three years.
| Item | Detail |
|---|---|
| Rate | 40% |
| Rate (special) | 50% |
| Cap | 10% of corporate tax for the period |
| Carryforward | Three years (conditional, below) |
| Application period | Five years from certification (or to plan end if earlier) |
| Certification deadline | From the effective date to March 31, 2029 |
What earns 50%
Note 3 of the outline defines it:
"Special priority industrial technology research expenses" means, of the priority industrial technology research expenses, those relating to research conducted jointly with a priority industrial technology joint research and development institution (provisional name) under the Industrial Technology Enhancement Act, or commissioned to such an institution.
Joint research with, or commissioning to, a certified institution. Research done alone is 40%.
If you are going for 50%, confirm the counterpart is certified. "Partner with a university and get 50%" is not the rule; certification is.
What gets missed
This is the part I most wanted to write. The outline's notes carry conditions that never make the headlines.
1. Being in one of the six areas is not enough
Note 4:
"Specified priority research and development" means research and development that has been confirmed to relate to a priority industrial technology (provisional name) under the Industrial Technology Enhancement Act (AI and advanced robotics, quantum, semiconductors and communications, bio and healthcare, fusion energy, space) that falls under certain criteria as one for which early commercialization is particularly expected.
"R&D that falls in one of the six areas" does not qualify. It must also meet criteria as work where early commercialization is particularly expected, and be confirmed as such.
I expect this to bite hard. Work close to basic research may struggle. Assuming "we do AI, so we qualify" will disappoint. The criteria will be set out in forthcoming orders and guidelines, so that is what to wait for.
2. Carryforward carries an extra condition
Note 5:
The carryforward credit may be applied only where, in the fiscal year in which the certified R&D corporation seeks to apply it, the amount of research expenses exceeds that of the prior period.
To carry unused credit forward, you must be increasing R&D spending that year.
That is demanding in practice. Run one large programme, fail to absorb the credit, and you must keep raising R&D spending to use what you carried over. For R&D that comes in peaks, the carryforward misses easily.
3. No double counting
From the main text:
priority industrial technology research expenses (excluding, where the general research expense credit, the SME technology base strengthening tax regime, or the special research expense credit is applied, the amount to which those apply)
The caps are separate, but the same spending cannot be counted twice. "It is a separate bracket so you can combine them" is half right. The bracket is separate; the expenses must be split.
4. The 10% cap sets the real number
To repeat, because it is the most important point.
Whether the rate is 40% or 50%, you can only take 10% of corporate tax for the period. With corporate tax of 100 million yen, this bracket yields at most 10 million.
However much you spend on R&D, a small tax bill limits the effect. And if you are loss-making, it does nothing.
This is structural for R&D-heavy startups. The period when you spend most on research and most need support is usually the loss-making period. A tax credit does not reach it. That is how the instrument works, so I state it as a fact rather than a complaint.
The second pillar is regulatory reform
Overshadowed by the tax measure, but the Prime Minister's post raises a second point.
Second, where a business that has received certification of an R&D plan in a "strategic technology area" needs existing rules revised in order to implement new technology in society, we will strengthen information-sharing arrangements within government and connect this to prompt consideration of regulatory reform.
Unglamorous, but I think this matters in more situations than people expect.
New technology stalls in Japan for reasons other than technical immaturity. It runs into a rule owned by a different ministry and nobody settles who decides, and time passes. Sharing information about certified businesses across ministries is aimed at reducing that stall.
That said, this content does not appear in the House of Councillors bill summary.1 It reads as a statement of intended government practice built on the certification scheme, rather than a statutory measure. The operational detail will have to wait.
Why this is a shift
Leaving the numbers aside, the policy thinking has changed.
The R&D tax credit has been neutral across sectors and fields. The premise was that you cannot know in advance where breakthroughs come from, so you support "companies that increased R&D spending" uniformly.
The new bracket is different. The state designates six areas by cabinet order and allocates heavily there — narrowed further to work where early commercialization is expected.
That is selection and concentration. Views differ on whether it is right, but the direction has clearly changed.
My own read: the judgment that "broad and thin" cannot keep pace internationally is understandable. From the US CHIPS Act to the EU's frameworks, major economies are picking areas and concentrating resources. Japan staying neutral loses on scale.
Equally, there is no guarantee winners emerge from the areas a government picks. That is an old argument, and only hindsight settles it. As built, the general regime remains for everything else, so it is a two-track system in practice.
The Growth Strategy's 17 fields are something else
This topic often arrives bundled with "the 17 strategic fields." That is separate from the six areas, so let me split them.
The Japan Growth Strategy was approved by Cabinet on July 21, 2026, and on the same day the Japan Growth Strategy Headquarters adopted the "Public-Private Investment Roadmap for Key Products and Technologies in the 17 Strategic Fields."3
The roadmap is titled as covering 17 strategic fields with 62 items in total. The fields are:
AI and semiconductors; digital and cybersecurity; information and communications; quantum; defence industry; synthetic biology and bio; drug discovery and advanced medicine; resources, energy security and GX; fusion energy; aviation and space; ocean; shipbuilding; materials (critical minerals and components); disaster prevention and national resilience; port logistics; food tech; content.
| Priority industrial technologies (6) | Strategic fields (17) | |
|---|---|---|
| Basis | Industrial Technology Enhancement Act (cabinet order) | Japan Growth Strategy (Cabinet decision) |
| Purpose | Defines the R&D tax credit scope | Defines public-private investment priorities |
| Instruments | Tax credit, certification, NEDO advice | Investment roadmap, budget allocation |
Seventeen fields is the list of industries to concentrate investment in; six areas is the subset getting heavy R&D tax support. Different scope, different tools.
The Prime Minister's post pairs the 17 fields with two further items under consideration:
Based on the Japan Growth Strategy, we will advance consideration of the "formation of new university groups" that will strengthen Japan's industrial competitiveness centred on the 17 strategic fields, and of "startup finance" matched to each stage
"Formation of new university groups" pairs with the opening observation that universities are growing as recipients of investment. A 50% bracket does not work if the universities on the other side lack the scale and structure to absorb corporate R&D money. It is of a piece with tying 50% to certified institutions.
There is a fact worth holding alongside this, though. The baseline funding of the national universities that would serve as those recipients has thinned over the past two decades.
Per MEXT figures, ordinary revenue across the national university corporations grew roughly 1.5 times, from 2,445.4 billion yen in FY2004 to 3,700.5 billion in FY2024. Yet operating grant revenue fell from 1,165.4 billion yen (47% of the total) to 1,082.8 billion (29%) — down in both absolute and relative terms.4 The growth came from university hospital revenue and external funds. Separately, the efficiency coefficient applied since incorporation in FY2004 cut roughly 1% a year, amounting to about 147 billion yen (11.8%) over the eleven years to FY2015.
So the picture of the last twenty years is universities leaning harder on external funding as their base thinned. A 50% credit draws in more of that external funding, but it does nothing to restore the capacity of the recipient itself. How far "formation of new university groups" goes needs reading in that context.
"Startup finance matched to each stage" connects to the cap problem below. A tax credit is an instrument for profitable companies, so loss-making R&D startups need funding from elsewhere. That is being handled separately.
The roadmap attaches figures to each item, but notes their basis itself: they were derived from working group discussions in each field under certain mechanical assumptions, and may be revised through the budget process. Treating the total as a settled figure is not appropriate.
What to do now
The scheme starts when the cabinet order takes effect, but preparation can start today.
1. Audit whether your R&D falls in the six areas. AI, robotics, semiconductors, communications, bio and space are broader concepts than they look. Lay out your research themes before concluding you are outside.
2. Then re-examine through the "early commercialization" lens. Being in an area is not enough. Can you articulate the distance to commercialization? This goes straight to how the plan is written.
3. Build the expense tracking. The R&D credit has always demanded documentation; personnel costs are limited to those exclusively engaged, with daily work records required. Starting after certification is too late.
4. Check whether your research partner will be certified. Forty versus fifty percent is a real gap, but certification is their decision. Have the conversation early.
5. Model the benefit from your corporate tax. With a cap at 10% of corporate tax, your tax bill determines the absolute benefit. Judge on yen, not on the headline rate.
6. Track the cabinet order and guidelines. Effective date, designation of priority technologies, confirmation criteria. None are out yet. Assigning someone to follow them is itself preparation.
Closing thought
Honestly, the companies best served here are already profitable, already investing consistently in R&D, and have the capacity to partner with universities. With a cap at 10% of corporate tax, that follows.
R&D startups are harder to reach. That is inherent to the instrument, and has to be filled by other means — grants, equity, procurement. The Growth Strategy's startup finance workstream exists for that reason.
The post closes:
Excellent scientific and technological capability is the foundation of the "strong economy" the Takaichi Cabinet is pursuing. (...) We will realize a "new technology-based nation," winning in technology and winning in business.
"Winning in technology, losing in business" is a line Japanese manufacturing has used about itself for decades. The message inverts it.
"Up to 50%" travelling alone will set expectations wrong. Look at your corporate tax, check the six areas, ask whether you can argue early commercialization, and find out whether you can partner with a certified institution. Working those four in order is the fastest route to an answer.
The detail lands with the cabinet order and guidelines. Follow the conditions, not the number.
Wrapping up
- The amended act is Act No. 41 of 2026, enacted June 12, promulgated June 19. Separate from the bold investment tax measure (No. 29)
- The effective date is set by cabinet order within a year of promulgation. Not yet decided
- The law establishes cabinet-order designation of priority technologies, certification of R&D plans, certification of joint R&D institutions, and a patent rule for commissioned research
- The credit is 40%, or 50% for joint or commissioned research with a certified institution
- Capped at 10% of corporate tax for the period. That sets the real number
- Being in the six areas is not enough. You need confirmation that early commercialization is particularly expected
- Carryforward applies only where R&D spending that year exceeds the prior period
- The same spending cannot be counted under the general regime as well
- Certification deadline March 31, 2029; application period five years from certification
- The Growth Strategy's 17 fields and 62 items are a separate framework, with figures based on assumptions and subject to revision
Tax policy has finally reached the territory behind "we win in technology and lose in business." I welcome the direction, but whether it bites depends on how the conditions are drawn. Waiting on the cabinet order.
