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

Quick answers. Before you book the call.
What's the time difference between Seoul and Tokyo?
Seoul and Tokyo 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 Seoul from Tokyo?
About 1,149 km as the crow flies (great-circle distance). A non-stop commercial flight cruises that in roughly 1h 51m, not counting airport time, winds, or routing around restricted airspace.
Can I send this meeting time as a calendar invite?
Yes. Pick a time on the slider above, open the meeting card, customize the title and duration, then download the .ics file. It imports cleanly into Google Calendar, Outlook, and Apple Calendar with the correct timezone attached.
What currency do Seoul and Tokyo use?
Seoul uses the South Korean won (KRW, ₩); Tokyo uses the Japanese yen (JPY, ¥). Check the live rate before transferring money or paying with a card abroad — most banks add a 1–3 % FX margin on top of the mid-market rate.
How do I call Seoul from Tokyo?
Dial the international prefix used by your carrier (often 00), then +82, then the local number — drop any leading zero of the city or mobile code. For free calls, WhatsApp, Signal, and FaceTime work over Wi-Fi regardless of country code.
What language is spoken in Seoul and Tokyo?
Seoul primarily speaks Korean; Tokyo speaks Japanese. English is widely used in business contexts in major cities of both, but written contracts may need translation.
Do Seoul and Tokyo drive on the same side of the road?
No. South Korea drives on the right, Japan on the left. If you're renting, expect a learning curve on the first day — especially at roundabouts and when judging the centre of the lane.
