When the world meets at work.
Read the day in both zones.
Crossing the border. Money, language, plugs.
Money changes hands at the border: Osaka uses the JPY (¥) and Seoul uses the KRW (₩). Language shifts too — Japanese in Osaka, Korean in Seoul. Be careful behind the wheel: Osaka drives on the left, Seoul on the right.

Quick answers. Before you book the call.
What's the time difference between Osaka and Seoul?
Osaka and Seoul share the same offset (GMT+9), so there's no difference right now.
When's the best time to schedule a meeting?
There are 8 hours where both cities are inside a 09:00–17:00 workday. Aim for the middle of that window so neither side is starting or closing out.
Does daylight saving time change the difference?
Yes, if either city observes DST. When one side shifts and the other doesn't, the gap changes by one hour. The DST badges under each clock show whether each zone is currently shifted and when the next transition lands.
How far is Osaka from Seoul?
