SusHi Tech Tokyo 2027完全ガイド：5月20〜22日開催決定、東京イノベーションウィークの全体像

The Tokyo Metropolitan Government has set its dates. SusHi Tech Tokyo 2027 will run May 20–22, following a 2026 edition that closed with 60,779 participants and 798 exhibiting startups. For executives and investors deciding where Tokyo fits in next year’s calendar, the announcement settles the “when.” This guide covers the rest: what SusHi Tech Tokyo actually is, what the 2026 results tell you about 2027, and how to build a week in Tokyo that produces decisions rather than badge scans.

One note of honesty up front. As of this writing, the Tokyo Metropolitan Government has confirmed the 2027 dates and little else — no venue, no theme, no program. Where this guide describes format, it draws on the 2026 edition and says so. We will update this page as official details land, just as we did with our SusHi Tech Tokyo 2026 guide.

What Is SusHi Tech Tokyo?

SusHi Tech stands for Sustainable High City Tech Tokyo — the Tokyo Metropolitan Government’s flagship platform for solving urban problems with technology, and the anchor event of Tokyo’s startup ecosystem push. The name is a deliberate play on sushi craftsmanship: take raw material, apply skill, produce something the world recognizes as distinctly Tokyo.

In practice, SusHi Tech Tokyo is a large-scale startup expo and conference. The 2026 edition, held April 27–29 at Tokyo Big Sight, combined a startup exhibition floor, keynote and panel programming, a city-leaders track for municipal delegations, structured business matching, and the SusHi Tech Challenge pitch contest. The first two days were business days for registered attendees; the final day opened to the public.

It matters because it concentrates Japan’s startup economy in one place — founders, corporate venture arms, institutional investors, and government delegations from around the world, all inside one exhibition complex over three days. If your firm is evaluating Japan for investment, partnership, or market entry, this is the week the whole ecosystem is reachable.

What the 2026 Numbers Say About 2027

The official 2026 results are worth reading closely: 60,779 participants, 798 exhibiting startups, and more than 25,140 business meetings held across three days.

Two of those figures deserve an executive’s attention. A startup count approaching 800 means the exhibition floor is now large enough that walking it without a plan wastes a day. And 25,000-plus structured business meetings is the more telling number: SusHi Tech has become a working dealmaking venue, not a showcase. The business-matching platform that produced those meetings is the single most useful tool for a first-time attendee, and it rewards early registration.

For 2027, expect the Tokyo Metropolitan Government to push for continuity at minimum. The dates — Thursday to Saturday, May 20–22 — suggest the established rhythm: business-focused days first, a public day to close. Venue and program are unannounced; we will not guess at them here.

How to Read an Innovation Week

Tokyo’s innovation week follows a pattern that will be familiar to anyone who has done Davos, VivaTech, or Web Summit: a headline event anchors the calendar, and the days around it fill with satellite gatherings — investor dinners, embassy receptions, corporate showcases, closed-door roundtables. The expo is where you find what is moving. The rooms around it are where commitments get made.

That distinction is worth taking seriously when you plan the trip. An exhibition floor with tens of thousands of participants is optimized for breadth: scanning startups, taking first meetings, reading the temperature of a market. It is poorly optimized for the conversations that justify a senior executive’s week in Tokyo — the ones about capital, partnership, and policy that need two hours and a closed door, not fifteen minutes and a booth.

It helps to know that the rooms on offer during a week like this come in three kinds. There is the exhibition floor itself: open, enormous, high-throughput. There are the open satellite events — meetups, showcases, receptions — which are useful for serendipity and hard to plan around. And there are the invitation-only gatherings, where an organizer has taken responsibility for who is in the room and built the agenda for decisions rather than discovery. Most executive weeks in Tokyo go wrong by overweighting the first two and leaving the third to chance.

The practical answer is to treat the week as two instruments. Use the expo for coverage. Use a curated room for depth. The question to ask of any satellite event is simple: who curates the list, and is the room built for people with your decisions to make?

Tech for Impact Summit: The Executive Summit Before the Expo, May 18–19

This is where we declare our interest. Tech for Impact Summit 2027 — the fourth annual edition — takes place in Tokyo on Tuesday and Wednesday, May 18–19, 2027, in the two days before SusHi Tech Tokyo opens. The venue will be announced in Q3 2026.

The format is the inverse of an expo. T4IS is an invitation-only summit for senior executives, investors, and policy leaders working on one question: how to deploy frontier technology against the world’s hardest problems, from climate to health to governance. No exhibition floor. Sessions run as keynotes, working panels, and closed-door strategy dialogues where the conversation can be candid because it stays in the room.

The speaker history gives a sense of the room. Past editions have featured Audrey Tang, Taiwan’s first Digital Minister; Taro Kono, Japan’s former Digital Minister; Charles Hoskinson, founder of Cardano, who has keynoted three years running; Kathy Matsui of MPower Partners; Yat Siu of Animoca Brands; GLOBIS founder Yoshito Hori; Ken Shibusawa; economist Jesper Koll; and Masaaki Taira, member of Japan’s House of Representatives. The full roster is on the speakers page.

The 2026 edition, held this past April under the theme “Beyond Boundaries,” ran the day before SusHi Tech opened, and the sequencing held up. Executives arrived in Tokyo one day early, spent it in concentrated sessions with the people they actually needed, and then went into the expo week with their most important conversations already had. For 2027 the summit expands to two days, keeping the same position in the week.

For organizations rather than individuals, T4IS partnership operates in three tiers — Catalyst, Vanguard, and Principal — each combining summit seats with a year-round presence across the Tech for Impact event series. Details are on the membership page.

Planning the Week: A Practical Sequence

If you are building a Tokyo itinerary around these dates, the sequence writes itself:

• Monday, May 17 — Arrive. Tokyo in mid-May is at its best: warm, pre-humidity, post-Golden Week, so the city is working at full speed.
• Tuesday–Wednesday, May 18–19 — Tech for Impact Summit. Two days of concentrated executive sessions before the expo crowds arrive.
• Thursday–Saturday, May 20–22 — SusHi Tech Tokyo. If 2027 follows the 2026 format, prioritize the first two business days for meetings and use the matching platform well before you land; the closing public day is lighter and good for a second pass at specific booths.

One trip, one week, both instruments: the curated room first, then the ecosystem at scale.

Book accommodation early; the event calendar makes mid-May a busy week for the city, and the neighborhoods convenient to the major venues go first.

The Invitation

SusHi Tech Tokyo 2027 registration will open through the official channels in due course, and this guide will be updated as the program takes shape.

Tech for Impact Summit works differently. Seats are not sold; they are offered. Applications for the 2027 summit have not yet opened — the waitlist is open now, and joining it means you will be among the first to receive an invitation when they do. If May 18–19 in Tokyo belongs on your 2027 calendar, that is the place to start.
