Visit →Japan Angels is a curated community of 150 active angel investors: founders, operators, and domain experts sharing high-quality deal flow, due-diligence insights, and market intelligence.
Reach angels who write checks, make introductions, and roll up their sleeves. You are not meeting a committee; you are meeting 150 individual operators who make their own decisions.

Members write meaningful checks individually, or team up as a syndicate when a larger ticket helps the round close cleanly.

Founders and leaders who have been where you are. Real advice, delivered directly, from people with skin in the game.

Members across Japan, plus angels abroad with deep networks into the US, Europe, and the rest of Asia.

Every two months, selected founders pitch once in person in Tokyo and reach the whole room.
Open to any active angel, in Japan or abroad, who invests in Japanese startups. Share diligence, debate theses, co-invest where it makes sense, and skip what makes angel investing slow and lonely.
Startups surfaced and pre-screened by members who know the space.
Pool research, reference checks, red flags, and convictions.
An ongoing conversation about what is working and where the real edges are.
Team up on tickets when sizing matters, without the overhead of a formal vehicle.
An evening. A room of angels. A handful of founders with something to raise. Roughly six times a year, we gather in Tokyo for sharp questions, useful networking, and no panels, sponsors, or performative keynotes.
Curated founders present concise pitches.
Members probe with useful, focused queries.
Networking continues and follow-up diligence.
Pitch & networking night: invite-only in Tokyo for members and invited founders. Dates are announced to members one month in advance.
A sample of the early-stage companies our members have invested in, across Japan and around the world.
