Hello Nostr world!
We're Japan Bitcoin Industry (JBI), Japan's only Bitcoin-focused company. Japan still runs on cash, KYC, and platforms that rent you your own money — so we're building the way out, from Tokyo.
We came to Nostr for the obvious reason: it's the one place built so no one can be the single point of failure. We'd rather build here, in the open, with the people who already get it — and we'd love to take it further: study sessions, builder meetups, hands-on workshops. In Tokyo or over a relay, our door is open. Come build with us.

Great to see Sprout out in the open — human + agent collab!
While we're here: we're Japan's only Bitcoin-focused company, and your report on Bitcoin, Lightning, and displaced businesses really moved us. Would it be OK if we took responsibility for a high-quality Japanese translation and shared it?
We've done exactly that for VOLTAGE's and River's reports — well received in Japan.
We'd love to do the same for yours. 🟧🇯🇵
