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.

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.
