FAQ
API Development in Japan — common questions
Do you invoice in JPY? +
Yes. We can invoice in JPY, USD, or EUR — whichever your finance team prefers. All prices are quoted excluding local tax; we can register for tax purposes where required.
What are your working hours for clients in Japan? +
Our core hours have a minimum of 3–4 hours of overlap with JST. For fast-moving projects we run daily standups scheduled at your team's convenience.
Can you sign an NDA before discovery? +
Always. We sign mutual NDAs before any technical discovery. We're happy to use your standard template or provide ours.
Do you work with Japan-based agencies as a white-label partner? +
Yes. We frequently partner with local agencies as a technical execution arm — under your brand, with your project management.
How do you handle data residency and privacy laws in Japan? +
We design each engagement around the applicable regime (GDPR, CCPA, DPDP, POPIA, etc.). Data lives in the jurisdiction you require, and we build with those constraints from day one.
