Visa & Entry

South Korean passport holders enter Japan visa-free for up to 90 days. No fee, no advance application. Passport must be valid for the duration of stay. Complete the Visit Japan Web registration (vjw.digital.go.jp) before travel to pre-register your customs and immigration declaration, which generates a QR code that speeds up arrival processing. This replaced the paper arrival card at most airports.

At immigration, biometric data (fingerprints and photo) is collected for all foreign nationals. The 90-day entry covers tourism, business meetings, and visiting friends or family. Working is not permitted. For stays beyond 90 days, a visa must be obtained at the Japanese Embassy in Seoul before travel. Extensions within Japan are possible at a Regional Immigration Bureau but require a valid reason and are not guaranteed.
