Japan in numbers
How many startups are there in Japan?

19 are tracked on VibeCrowd, of which 13 have revenue confirmed through a payment provider. Together they collect $6K in a 30-day window — a small share of all startup revenue we track.

Which is the highest-earning startup in Japan?

Sidestack.io, in SaaS, at $2K over the last 30 days.

Where does Japan rank globally?

#49 of 124 markets by combined revenue, and #46 by number of startups. Those two positions rarely match: volume and money concentrate in different places.

How current are these figures?

Rebuilt from live data every hour. Revenue comes from payment-provider connections rather than founder questionnaires, so nothing here is self-reported.
