Expo 2025 Osaka offered something rare: a venue where the latest technology and genuine entertainment converged in a way that worked for children and adults simultaneously. Rather than passive exhibitions, the best pavilions were designed as participatory experiences — ones where visitors became part of the content rather than spectators to it.
This article ranks the top 10 pavilions as experienced by a 5-year-old, based on actual attendance at the Expo. The ranking reflects child-level engagement, but the experiences described have implications for anyone thinking about how technology, education, and entertainment intersect in a corporate context.
The Expo's closing month is approaching. If you are still planning a visit, use this list.

Pavilions 10-6: Innovative Corporate Experiences
#10 — US Pavilion
The space-themed US Pavilion was the most visited pavilion at the Expo. No reservation required, but lines routinely reached 2+ hours at peak times. During off-peak morning hours, the same pavilion took approximately 20 minutes to enter. Inside, a stage shuttle experience simulated the sensation of launching into space — rocket footage, a moon rock, and production values that impressed children and adults equally.
#9 — Pasona Group Pavilion
The Pasona Group Pavilion used Astro Boy and Black Jack animations as its framing content — familiar characters from Japanese animation history that connected immediately with children. 3D displays, a simulated underground exploration experience, and character-based content created a pavilion that was genuinely child-friendly without feeling simplistic.
#8 — Kansai Pavilion "Tottori"
The Kansai Pavilion combined real sand from Tottori Prefecture with projection mapping — an unusual combination that produced visually striking results. A magnifying glass exploration element let children observe the micro-scale details of natural materials, connecting science and natural observation in an accessible way.
#7 — Tech World Pavilion
A touch panel-based experience that let visitors "transform" into a superhero in virtual space — their real movements linked to an on-screen digital avatar. The technology was smooth enough that the gap between physical movement and digital response felt minimal. A special commemorative gift for all participants made the visit memorable for children beyond the experience itself.
#6 — NTT Pavilion
The NTT Pavilion used the company's IWON technology to deliver a video experience that went beyond screens: vibration was incorporated alongside visual and audio elements, creating a communications experience that visitors could feel. A Perfume performance integrated sound and imagery in a way that worked as pure entertainment while demonstrating where communication technology is heading. Room-by-room reveals inside the pavilion created a sense of progression and discovery.

Pavilions 5-2: Interactive Technology and Education
#5 — Kuwait Pavilion
The Kuwait Pavilion's built-in slide and sand excavation treasure-hunt experience were immediate hits with children. A planetarium-style final room — visitors could lie down and look up at a recreated night sky — created a genuinely contemplative ending to a pavilion that had been playful throughout.
#4 — Panasonic "Nomo no Kuni" Pavilion
Glowing stones that produced unexpected sounds and visual responses when touched made the Panasonic pavilion immediately interactive. The pavilion's design was deliberate: multiple different causes produced different effects, giving children a reason to experiment rather than just observe. This is educational without being didactic — the lesson about cause and effect emerges from play rather than instruction.
#3 — Power Hall Pavilion
The Power Hall Pavilion ran like a science museum: visitors could experience the physics of energy collection through hands-on experiments, including an egg-based energy concentration activity and a game modeled on "statues" (Red Light, Green Light) that generated electricity. Art installations exploring light as stored energy connected the entertainment to a larger point about energy's future.
#2 — Gundam Pavilion
The Gundam Pavilion delivered theme park quality in a trade fair setting. A space elevator simulation transported visitors to "space," where a battle sequence with Gundam units followed. The production quality and immersion were described by multiple visitors as matching Universal Studios Japan and Tokyo Disneyland — high praise in Japan's competitive entertainment market.
No. 1: Sumitomo Pavilion — The Complete Experience
The Sumitomo Pavilion was the most innovative experience at the Expo, and the one most worth building a visit around.
Rather than a fixed route through a sequential exhibition, the Sumitomo Pavilion gave each group a lantern and released them into a simulated forest to explore freely. Hidden messages, digital art, and interactive elements were distributed throughout the space — visitors discovered them at their own pace. No two visits were the same, because no two groups took the same path.
The climax was the "Multi-Ming Theater" — a space where sound, light, wind, and mist combined into a narrative that responded to visitor movement. This was not a video you watched; it was an environment you influenced. Children who had been exploring with lanterns suddenly found themselves in a space where the forest itself was reacting to their presence.
The experience worked as entertainment, as art, and as an education in how digital and physical can be designed to reinforce each other rather than compete. For business observers, it was also a case study in how a major corporation can use an Expo pavilion to communicate values — stewardship of the natural world, the relationship between human curiosity and technology — without making those values feel like marketing.
Summary
Expo 2025 Osaka's child-focused experiential pavilions demonstrated a consistent principle: the most memorable experiences were participatory, not passive. The Sumitomo Pavilion's free-exploration lantern forest, the Gundam Pavilion's battle simulation, the NTT Pavilion's haptic video experience, and the Panasonic Pavilion's interactive stone displays all required something from the visitor rather than delivering content to them.
For business professionals evaluating how to present technology or brand values in an event context, these pavilions were useful reference points. The question they collectively answered: what does it look like when a company translates its R&D into something a five-year-old finds irresistible?
