SusHi Tech Tokyo 2026 完全ガイド：東京最大のイノベーションウィークの全貌

SusHi Tech Tokyo 2026, the Tokyo Metropolitan Government’s flagship programme for sustainable technology and startups, returns to Tokyo Big Sight from April 27 to 29. The organisers expect over 700 startups, 60,000 participants, and delegations from more than 20 countries.

This guide covers the dates, the venue, the four themes, and where Tech for Impact Summit sits in the week.

What SusHi Tech Tokyo is

SusHi Tech Tokyo, short for Sustainable High City Tech Tokyo, is the Tokyo Metropolitan Government’s platform for sustainable innovation. It launched in 2023 as the centrepiece of TMG’s “10x10x10 Innovation Vision,” a plan to multiply Tokyo’s startups, unicorns, and public-private collaborations tenfold within five years.

Attendance went from 26,000 in the first year to over 40,000 in 2024 and 57,000 in 2025. The 2025 edition drew participants from 100 countries, 607 startup exhibitors and 6,000 business meetings, with speakers including Audrey Tang and Kathy Matsui.

The 2026 targets: 700+ startups, 60,000+ participants, and 10,000+ projected business meetings.

Keidanren, Keizai Doyukai, and the Japan Association of New Economy back the event.

The four 2026 themes

AI

The headline theme. Sessions cover human-AI collaboration in practice, from autonomous systems and generative AI to governance frameworks, with senior executives from NVIDIA, NEC, and Fujitsu alongside AI researchers from Japanese universities.

Robotics and autonomous systems

Japan’s population is shrinking and ageing, which is the background to this track. It covers autonomous systems moving from prototype to deployment across Japanese industry, from warehouse automation to elder care.

Resilience

Urban planners, emergency response leaders, and infrastructure technologists on how cities prepare for climate disasters, cyber threats, and supply chain disruptions.

Entertainment

A Tokyo-specific track on how technology is changing music, gaming, animation, art, and food, and on the business models Japan’s creative industries are building abroad.

Partner events

SusHi Tech Tokyo runs as an innovation week. The Tokyo Metropolitan Government invites organisations to host partner events in the days around the main programme: workshops, dinners, networking sessions, cultural events, held across the city rather than in the exhibition halls.

The main floor at Tokyo Big Sight is large and startup-focused. Partner events are where the smaller, more senior rooms tend to be.

Tech for Impact Summit

Tech for Impact Summit 2026 takes place on Sunday, April 26, the day before SusHi Tech opens, at Kioi Conference in Nagatacho, Tokyo’s political and business district.

It is an invitation-only gathering of senior executives, investors, and policy leaders on deploying technology against humanity’s most urgent challenges.

The confirmed lineup includes:

• Taro Kono (河野太郎) — Former Digital Minister of Japan
• Charles Hoskinson — Founder of Cardano
• Yoshito Hori (堀義人) — Founder and President of GLOBIS, delivering the keynote
• Kathy Matsui (キャシー松井) — General Partner, MPower Partners
• Ken Suzuki (鈴木健) — Founder and CEO, SmartNews
• Jesper Koll — Expert Director, Monex Group
• Sota Watanabe (渡辺創太) — Founder, Astar Network / Startale
• Ken Shibusawa (渋澤健) — Founding Partner, Commons Asset Management
• Hiroshi Aoi (青井浩) — CEO, Marui Group
• Kiyoshi Seko (世古貴代志) — COO, Kyoto Fusioneering

Sessions cover Web3 and digital infrastructure, clean energy and fusion, impact investing, AI governance, and ESG strategy, plus closed-door Strategy Dialogues under Chatham House Rules.

Past editions have featured Audrey Tang, Takuya Hirai, and Charles Hoskinson. See the highlight video from 2025.

The format differs from SusHi Tech’s main programme: smaller rooms, longer conversations, no exhibition floor.

Why the week is worth a trip

Two formats in one week. SusHi Tech has the breadth: hundreds of startups, thousands of business meetings, delegations from 20+ countries. Tech for Impact Summit has a smaller room where the conversation is about what participants will do next.

Japan in 2026. Regulatory changes in Web3, a weak yen drawing record inbound investment, corporate governance reforms, and the world’s oldest society becoming a testbed for robotics and healthcare technology.

Two different crowds. SusHi Tech draws the startup ecosystem. Tech for Impact Summit draws the people who fund, regulate, and deploy technology at scale. Attending both covers the whole chain.
