Visa & Entry

Japanese passport holders enter South Korea visa-free for up to 90 days. No fee, no advance registration. Passport must be valid for the duration of stay. K-ETA (Korea Electronic Travel Authorization) was required from 2021 to 2023 but has been suspended for Japanese nationals through the end of 2025. If K-ETA resumes, it costs KRW 10,000 (about JPY 1,100) and takes 24 to 72 hours to process at k-eta.go.kr.

Entry is fast. Immigration at Incheon (ICN) typically takes 15 to 30 minutes with automated gates available for repeat visitors who register biometrics.
