SusHi Tech Tokyo 2027 is an innovation and startup event held in the Japanese capital, and the organiser has scheduled it for 20 to 22 May at Tokyo Big Sight. The year is 2027. The event uses Tokyo Big Sight, using West Exhibition Halls 1, 2, 3 and 4 together with other areas of the complex in Ariake, Koto ward. The organiser splits the three days by audience, designating Thursday 20 May and Friday 21 May as business days and Saturday 22 May as a public day, so the commercial programme and the general admission element are deliberately separated rather than blended. The event's full name is given as Sustainable High City Tech Tokyo, from which the abbreviated brand derives, and the 2027 gathering is identified as the fifth edition.
The organiser is named as the SusHi Tech Tokyo Executive Committee, and the event's official site is published on the Tokyo Metropolitan Government's own web domain, which places the gathering within the city government's innovation activity rather than in the hands of a commercial exhibitions business. Tokyo Innovation Base, the city's startup support facility, also appears on the event's pages. That public sector origin distinguishes the event from most gatherings of comparable size, because its purpose is explicitly tied to a municipal policy objective rather than to exhibition revenue.
The figures the organiser publishes relate to the 2026 edition rather than to 2027, and it reports 798 participating startups, more than 25,140 business meetings and 60,779 participants for that year. The counting of business meetings is itself informative about the event's design, since it indicates that matchmaking between founders, corporates and investors is treated as the primary output rather than attendance alone. The thematic framing, carried in the event's full name, is the application of technology to sustainable urban living, which in practice spans the climate, mobility, energy, infrastructure and digital services that city systems depend on, alongside the general startup and venture programme.
The audience is threefold: founders and startup teams seeking capital, customers and partners; venture capital and corporate venture investors; and the corporate development, procurement and innovation functions of established companies looking for technology and suppliers. Public sector participation is part of the mix as well, given the organiser's composition. The explicit separation of business days from the public day means senior executives can attend the commercial portion without the dilution that a consumer facing audience usually brings, which is a practical consideration for anyone planning a schedule of meetings.
The event matters because of what Tokyo is attempting. Japan has historically converted its research strength and corporate scale into startup formation at a lower rate than comparable economies, and both the national government and the Tokyo administration have made increasing that rate an explicit policy aim, with the city building institutions and events to attract founders and investors from outside Japan. For executives at established Japanese companies, the event is one of the more accessible routes to external technology and partnership at a time when corporate venture activity is expanding. For investors and founders outside Japan, it is a point of entry to a market that is large and well capitalised but historically difficult to enter without local relationships. The analytical question an executive can usefully take to it is whether that policy push is producing companies of genuine investable quality, and an event built around counted business meetings is a reasonable place to form a view.
