Japanese passport holders can enter Korea without a K-ETA until Dec. 31, 2026, but they still need to file an arrival declaration. Here is what to sort out before you fly, from official pages checked on Oct. 22, 2026. Rules change, so re-check the official sites before departure.
K-ETA: exempt through the end of 2026
According to the Consulate-General of Korea in Hiroshima, Japan is one of 22 countries and regions on Korea's temporary K-ETA exemption list, running from Jan. 1 to Dec. 31, 2026. For a short tourist stay you can enter without one.
You can still apply voluntarily. It lets you skip the arrival card, and it costs money: the official K-ETA site shows KRW 10,000 and says review usually takes up to 72 hours.
e-Arrival Card: 3 days before landing, free
Without a K-ETA, you file an arrival declaration. Korea's immigration service launched the e-Arrival Card on Feb. 24, 2025. Submit it at e-arrivalcard.go.kr from three days before arrival (Korea time). There is no fee.
If you don't enter within 72 hours of submitting, it becomes void and you file again. Children under 14 are declared by a family member. Paper cards were accepted alongside it until December 2025, so filing online is the safe option now. Use the official site, not look-alike pages in search results.
Plugs and voltage
Korea runs on 220 V with Type C and F sockets (two round pins). Japanese flat two-pin plugs won't fit, so bring an adapter.
Japan is 100 V nationwide. Chargers marked 100-240 V only need the plug adapter; a Japan-only 100 V device such as a hair iron needs a transformer. Check the label before you pack.
