No. The difference is 6 hours for the whole of 2026: neither city observes daylight saving time.
Best time to call Istanbul from Tokyo (and vice versa)
The window in which both cities are inside their 9:00–17:00 working day runs from 15:00 to 17:00 in Tokyo, which is 09:00 to 11:00 in Istanbul: 2 hours of overlap per day. For a call that disturbs nobody, aim for the middle of that window.
Outside that window, the practical rule: mornings in Tokyo are afternoons in Istanbul. Avoid any hour that falls before 8:00 or after 21:00 in either city.
