This guide covers Japan’s public funding only: grants, subsidies and competitions. Two quick distinctions:
- Grants & subsidies - non-dilutive public money you keep (Tokyo city rounds for early stage, NEDO and JST for deep-tech R&D).
- Competitions - pitch contests with prize money (Tokyo Startup Gateway).
Looking for equity, mentorship or a cohort instead? Accelerators and incubators (Techstars Tokyo, Antler, Plug and Play) live in the Support, accelerators & incubators guide, and visa routes are in Visas for founders.
One timing note
Amounts, eligibility and deadlines reset every fiscal year (Japan’s year starts in April, and many calls open around December to January). Treat the listed figures as a guide, then confirm the current round on each official page before you plan around a number. The list below was checked against each official page on 20 October 2026.
