What is the time difference between Tokyo and Brussels?

Tokyo (JST, UTC+9) is 8 hours ahead of Brussels in winter (CET, UTC+1) and 7 hours ahead in summer (CEST, UTC+2). Japan does not observe Daylight Saving Time, so the gap shifts only when Belgium moves its clocks in spring and autumn.

Does Tokyo observe Daylight Saving Time?

No. Japan abolished DST in 1952 and has not used it since. Tokyo stays on JST (UTC+9) all year. Only Brussels shifts its clocks twice a year, which is why the Tokyo-Brussels gap alternates between 7 and 8 hours.

When does Belgium switch between CET and CEST?

Belgium moves clocks forward to CEST (UTC+2) on the last Sunday in March at 02:00 CET, reducing the Tokyo gap from 8 to 7 hours. Clocks move back to CET (UTC+1) on the last Sunday in October at 03:00 CEST, returning the gap to 8 hours.

What are the best meeting times when calling from Tokyo to Brussels?

In winter (CET), Tokyo at 17:00–18:00 JST equals Brussels at 09:00–10:00 — a good window for both sides. In summer (CEST), Tokyo at 17:00–18:00 JST equals Brussels at 10:00–11:00, giving a slightly wider overlap.

Is this tool accurate for scheduling?

Yes. It uses the IANA timezone database embedded in your browser — the same source used by operating systems and calendar apps worldwide. Accuracy depends on your device clock being synchronized via NTP, which most devices handle automatically.

What is CET and CEST?

CET (Central European Time) is UTC+1 and is used by Belgium in winter. CEST (Central European Summer Time) is UTC+2 and is active from late March to late October. Brussels switches between the two each year.

Summary

This tool displays the live current time in both Tokyo (Asia/Tokyo — JST, UTC+9, no DST) and Brussels (Europe/Brussels — CET UTC+1 in winter, CEST UTC+2 in summer) side by side. Because Japan never observes Daylight Saving Time and Belgium does, the gap between the two cities shifts twice a year: Tokyo is 7 hours ahead of Brussels in summer (CEST) and 8 hours ahead in winter (CET). Use this page to schedule Japan-Belgium calls, coordinate remote teams, or plan travel between Asia and Western Europe.

How it works

Your browser reads the current moment from your device clock.
It converts that moment to Asia/Tokyo time (JST, UTC+9) using the IANA timezone database built into modern browsers.
The same moment is converted to Europe/Brussels time (CET or CEST depending on the season).
The UTC offsets of both cities are compared to calculate the exact hour difference.
All three values — Tokyo time, Brussels time, and the offset — refresh every second.
When Brussels switches between CET and CEST, the displayed offset adjusts automatically between +7 and +8 hours.
