Two Tokyo tech roles expose very different access gates
Fresh security and AI-software listings show why international candidates must distinguish language requirements from residence and work-authorization conditions.
Developments
Two newly dated Tokyo technology vacancies illustrate a recurring trap for international candidates: a role can look globally oriented while its practical access gate sits somewhere else. Language level, current residence, work authorization, and technical specialization need to be read separately.
1. OKCoin Japan opens a security role without an existing work-permission gate
OKCoin Japan’s security-engineer advertisement covers application and API vulnerability assessment, security monitoring products, incident response, intrusion prevention, and internal training. CareerCross lists daily-conversation Japanese and English and says existing permission to work in Japan is not required. That wording expands the apparent applicant pool, but it does not itself promise sponsorship, so overseas candidates should verify the immigration process before treating the role as reachable. The compensation is negotiable, and the annual-pay terms include 45 hours of deemed overtime, making the detailed employment conditions as important as the technical remit.

2. Recursive wants applied AI breadth but limits applications to Japan residents
Recursive’s software-engineer role spans prompt and orchestration pipelines, model deployment, retrieval-augmented generation systems, and backend APIs. It asks for fluent English and basic Japanese, yet the decisive restriction is geographic: applicants must already live in Japan with valid status. For candidates comparing AI roles, this is a reminder that a modest Japanese requirement does not necessarily make a vacancy accessible from abroad. (Review the TokyoDev listing)
What candidates should take away
Treat every access condition as its own field. A listing may welcome international experience, use English at work, or waive an existing work-permission requirement while still imposing a residence, language, or immigration hurdle. Confirm those conditions directly before investing heavily in an application.
