TIB SANDBOX opens its September pitch stage to early-stage founders

Tokyo Innovation Base (TIB) has opened TIB SANDBOX, a pitch event for startups at the idea and earliest launch stages. The event is scheduled for September 30, 2026, from 6:30pm to 8:30pm at 1F LIVING in Tokyo Innovation Base, and the official listing is recruiting both presenters and audience members.

For a founder who has moved beyond a private concept but is still testing how to explain the business in a room full of people, that is a useful distinction. This is a public pitch setting built for an early stage, rather than a program that assumes a polished fundraise or an established customer base. The announcement gives the event's Peatix registration page as the route to participate.

Tokyo Innovation Base is the Tokyo Metropolitan Government's startup hub in Yurakucho. Its events can put first-time founders in the same room as other builders, operators, and people following the local ecosystem. A pitch slot may be relevant if you want practice making the problem, customer, and next step intelligible in a short format. Attending can be the lower-commitment option if you are still working out what a credible early-stage pitch sounds like in Japan.

What founders should know

The official notice is brief, so check the Peatix page for the current registration details and any presenter conditions before making plans. It confirms the date, time, venue, and that both pitching and viewing are being recruited, but it does not set out application criteria or selection rules in the announcement itself.

If you want to pitch, prepare a plain explanation of what you are building, who it is for, and what you need next. At this stage, clarity matters more than a grand story. If you plan to attend, treat the evening as a chance to listen for the questions early teams receive and to see how different founders frame an unfinished business.

TIB SANDBOX takes place on September 30, 2026 at Tokyo Innovation Base. Registration and the latest event information are on the official listing below.
