Three numbers. The ones that decide the meeting.
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 Reykjavík uses the ISK (kr). Language shifts too — Japanese in Osaka, Icelandic in Reykjavík. Be careful behind the wheel: Osaka drives on the left, Reykjavík on the right.

Quick answers. Before you book the call.
What's the time difference between Osaka and Reykjavík?
Osaka is 9 hours behind Reykjavík. Osaka runs on GMT+9 and Reykjavík on GMT+0. The gap can shift by an hour when either side enters or leaves daylight saving — the live clocks above always reflect the current offset.
When's the best time to schedule a meeting?
Standard 09:00–17:00 workdays don't intersect. Most teams compromise with one side meeting early (before 09:00) or late (after 17:00).
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 Reykjavík?
About 8,847 km as the crow flies (great-circle distance). A non-stop commercial flight cruises that in roughly 10h 55m, not counting airport time, winds, or routing around restricted airspace.
