Tokyo Game Dungeon 15
Overview
An exhibition of indie games made by individuals and small teams in Japan. It accepts applications first-come-first-served with no jury screening, offering an affordable exhibitor fee and well-equipped booths. The organizer is himself a solo developer and keeps the event a gathering of game-making peers rather than a business matchmaking floor. Held several times a year, it sets aside around 300 exhibitor slots.

- Indie game developer Iwasaki formed a preparatory committee and held the first edition in August 2022
