Founder communities in Tokyo: 14 compared (2026)

The right founder community in Tokyo is the one you'll go back to: a pitch social in Shibuya, a Tuesday lunch at Tokyo International Forum, a Saturday run from Harajuku or a free hub in Marunouchi. Below are 14 communities, each checked on its own pages, with what each costs, how to get in and when it next meets.

A note before you read on: this guide is published by Remote Builders, our own free community for founders who build companies remotely, which you can join online from Tokyo. It isn't in the table, because it doesn't meet in Tokyo. We've left out any number we couldn't find on a community's own page.

How to choose a founder community in Tokyo

Evenings, lunches and runs

• HN Tokyo is a social evening for entrepreneurs, founders and technologists at TENCUPS in Shibuya, with no formal presentations but an open pitch slot about halfway through. Meetup #128 was on 19 October 2026, entry is ¥1,500 in cash including one drink, and recruiters are generally not allowed.
• Tokyo Startup Lunch Club meets every Tuesday at 12:00 at Tokyo International Forum in Marunouchi, with no pitches or presentations; bring lunch or buy from the food trucks. The last lunch listed as held was on 4 August 2026.
• Drinks With Founders Tokyo runs themed evening nomikai at a bar in Jinnan, Shibuya, with no presentations and no slides, for newer founders who want to learn from veterans. Its latest, on payments and fintech, was on 21 October 2026.
• Founders Running Club Tokyo runs an easy 5K from Deus Ex Machina Harajuku on Saturdays at 9:00, then coffee. Events are in English, and the next run is on 31 October 2026.

International founders and free hubs

Shibuya Startup Support is a Shibuya City Office programme for international founders, with a weekly Snack & Connect (next on 4 November 2026) and a monthly Growth Hub, whose 18th edition with Coral Capital was on 21 October 2026; it runs its Startup Visa programme in English. Tokyo Innovation Base, at 3-8-3 Marunouchi, is free to use once you register as a member, with weekly meetups, a founder-to-founder Scramble Meetup, a women leaders' roundtable and a monthly TIB PITCH. Venture Café Tokyo holds a free Thursday Gathering at CIC Tokyo in Toranomon, and Startup Hub Tokyo in Marunouchi is a free support hub for people preparing to start a business, with a site in Japanese.

Women founders

• HerRise: six free workshops in Shibuya, organised by Shibuya City and run by Startup Lady, for women entrepreneurs within about 10 years of founding. Step #4, on finance and fundraising, is on 11 November 2026; business-level Japanese is recommended.
• APT Women: a three-month Tokyo Metropolitan Government programme of lectures and mentoring for women founders based in, or expanding to, Tokyo. The domestic programme runs online, its 11th cohort kicked off at Tokyo Innovation Base on 11 September 2026, and public events are free.

Accelerators and programmes

Techstars Tokyo, powered by Mitsui Fudosan and JETRO Startup, is a three-month programme that invests $120,000 (currency not named); its class showcase in Shibuya is on 30 October 2026. Antler Japan runs a six-week residency with no fee, invests $150,000 (currency not named) for 10%, and starts its next Tokyo cohort on 2 November 2026.

Google for Startups Campus Tokyo, at Shibuya Stream, runs founder lunches and AI sessions in English with Japanese automatic translation, most recently Build with AI on 28 May 2026.

Founder communities in Tokyo compared

These are 14 communities. We checked the 12 new rows on 28 October 2026, and Venture Café Tokyo and Startup Hub Tokyo on the same day for our East Asia guide. Every row was active when we checked: an event, intake or post dated May 2026 or later, or open registration for an upcoming event. "Says" means the figure is the community's own claim.

Notes on the table

• Upcoming events. Techstars Tokyo's networking night is on 28 October, Venture Café's Thursday Gathering on 29 October, Techstars' showcase on 30 October, Founders Running Club on 31 October, Antler's cohort starts on 2 November, Snack & Connect is on 4 November, HerRise Step #4 on 11 November, Tokyo Innovation Base's ecosystem day on 25 November and Open Network Lab's 32nd batch starts in mid-December.
• Event dates from page code. Some dates come from the event data in Luma's page code rather than the page text; each profile says which.
• Japanese-language pages. Some pages are in Japanese; we quote them in Japanese on each profile and describe them in English here.
• Approval. HerRise needs host approval, Google for Startups Campus Tokyo asks you to request to join, and Techstars, Antler, Open Network Lab and APT Women take applications.

Communities we checked and left out

We left out groups that are gone or that we couldn't read, groups with no in-person Tokyo activity since May 2026 (including some that moved online and a startup loft that closed), groups whose pages don't say they're for founders, a pitch event startups can't attend as audience, a coworking offer, a very small group with two events and a page of corporate press releases. We didn't find an indie hacker, SaaS or bootstrapper group, or a web3 founder group, in Tokyo that met our checks; if you run one, tell us and we'll check it.

Tokyo's founders in numbers

Startup Genome's 2026 Tokyo page says SusHi Tech Tokyo 2026 recorded 750+ startups, 10,000 business meetings and 60,000 participants, and that Tokyo Innovation Base membership grew from 23,000 to 67,000+ since 2023, with events up from 480 to 1,400+. It puts the Tokyo Metropolitan Government's 2026 startup budget at $448M (currency not named), up from $325M in 2024, and says Japan expanded its startup visa nationwide in 2025, letting foreign entrepreneurs stay for up to two years.

How to get value in your first month

1. Pick one weekly thing and one monthly thing. A Saturday run or a Tuesday lunch, plus HN Tokyo or a Growth Hub evening.
2. Go to the same one three times. By the third, people know what you're building.
3. Bring one specific ask. "I need an intro to a founder who has sold to Japanese enterprises" gets you somewhere.
4. Start in English if you need to. Shibuya Startup Support, Founders Running Club Tokyo and Google for Startups Campus Tokyo run in English.
5. Add a broader group. Our East Asia guide covers Osaka, Fukuoka, Seoul, Taipei and Hong Kong, and our comparison of communities for remote founders covers the online options.

Common mistakes

• Only going to big summits. The small formats, like a lunch with no pitches or a nomikai with no slides, are where you get real help.
• Saying yes to everything. Pick two or three and go often.
• Planning around an old date. Several of these groups post dates late, so check the listing the week before.
• Waiting for the perfect group. If nothing fits your niche, start one. Our guide to starting a founder meetup covers the first three events.
