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.

ICN–KIX Quick Facts
Frequently Asked Questions
Seoul Incheon to Osaka Kansai: Northeast Asia's High-Frequency Corridor
ICN-KIX is among the most-flown international routes in Asia, driven by strong tourism exchange between South Korea and Japan's Kansai region. The 1 hour 30 minute flight connects two of Asia's largest international hubs. Korean carriers hold the majority of capacity: Korean Air, Asiana, Jin Air, Jeju Air, T'way Air, and Air Busan collectively operate 20 or more daily departures. Japan Airlines and Peach Aviation add Japanese-side frequency. Aircraft are predominantly A320-family narrowbodies and Boeing 737-800s. Incheon Terminal 1 handles the full-service carriers; LCCs typically use Incheon Terminal 2 or the dedicated low-cost satellite.
Kansai Context and Terminal Notes
Osaka Kansai International sits on an artificial island 5 km offshore in Osaka Bay. Terminal 1 handles full-service international arrivals including Korean Air, Asiana, and Japan Airlines. Terminal 2, which opened for LCCs, is physically separate and connected by shuttle bus. Passengers combining flights across terminals at KIX face a 15–20 minute transit. The route carries heavy inbound Korean tourism to Kyoto, Osaka, Nara, and Kobe, and outbound Japanese travel to Seoul. Both directions peak during Japanese Golden Week, Korean Chuseok, and the summer months. Incheon handles customs smoothly with automated e-gate clearance for Korean and some foreign passport holders.
