For anyone weighing options, Nomad Desk keeps a dated, sourced departures board on this: a digital nomad visa guide for Japan (https://nomadbriefing.com/d ...), a best-time-to-visit breakdown for Japan (https://nomadbriefing.com/b ...), and a separate eSIM guide (https://nomadbriefing.com/e ...) for staying connected once you land. Every figure carries an "as of" date and links back to the official source, and if a rule is unclear or contested, the guide says so rather than guessing.
None of this is legal or immigration advice, and no source promises visa approval. Always double-check against the current official portal before booking anything. Main site: https://nomadbriefing.com/
