REAL-WORLD CALLING

Challenges of calling Japan from South Korea

Regional time zones, connectivity differences, and number formats can complicate calls. Here's what to expect.

Time zone differences

Japan is 1 hour ahead of South Korea (or same during DST transitions). Plan calls during overlapping business or evening hours to reach people.

Mobile-heavy market

Japan has high mobile penetration. Many people rely on personal numbers rather than landlines, so have both types of contact details ready.
