How to pitch angel investors in Japan

Pick the ten to twenty whose stages and sectors match your round, open each profile, and write a short first email that names one of their past investments and says why yours is the next one. Round Funded sends from your own Gmail, tracks opens and replies, and keeps every thread in your pipeline.

Frequently Asked Questions

How many angel investors in Japan are there?

Round Funded lists 136 angel investors in Japan with a public profile and photo. This page shows the top 50, ranked by profile completeness and track record, and the full set is searchable inside the product.

Are these angel investors actually writing checks right now?

The catalog they come from is sourced from investors with a check in roughly the last six months and refreshed on an ongoing basis. Round Funded does not verify each investor's deals in real time, so use the list as a starting point and confirm on the profile.

How do I contact the angel investors on this list?

Open any profile for stages, sectors and past investments. Email addresses are available inside Round Funded after you sign up, and outreach is sent from your own Gmail so replies land in your inbox, not in a shared sending domain.

What check sizes do angel investors in Japan write?

Investors on this list show check sizes from $138K to $3.8M on their profiles. Treat it as a range, not a quote: the number on a profile is a typical amount, and most angels flex for the right deal.

How is this list ordered?

Profiles with complete public information come first, then investors with more past investments, then name. It is a ranking of how much we know about each investor, not an endorsement or a ranking of returns.
