About this tool
Convert time between Rome and Tokyo with live clocks and the current, daylight-saving-aware time difference.
See what time it is in Tokyo when you know the time in Rome — this converter shows both cities' clocks live and the exact current time difference between them, adjusted automatically for daylight saving. Rome runs on the Europe/Rome zone (CET) and Tokyo on Asia/Tokyo (JST); the tool reads your browser's own time-zone data, so the offset is always right even across the days each city changes its clocks. Type any Rome time to pin the matching Tokyo time, or press swap to convert the other way. Nothing is uploaded.
Open Rome to Tokyo Time Converter on AltFTool — it loads instantly in your browser.
Read the live clocks at the top for the current time in Rome and Tokyo.
Type a specific time into the Rome field to see the matching Tokyo time and date.
Press swap to convert Tokyo times to Rome instead.
The current local time in Rome and Tokyo updates every second, with each city's UTC offset and abbreviation shown.
Offsets come from the browser's IANA time-zone database, so the difference is correct on either side of a daylight-saving change — no stale table.
Enter a specific Rome time to see the exact Tokyo time for today, including the date if the conversion crosses midnight.
It runs entirely in your browser — no account, and no times are sent anywhere.
It can change through the year because one or both cities observe daylight saving, so the converter above shows the current difference live rather than a fixed number. Rome uses Europe/Rome and Tokyo uses Asia/Tokyo.
Type 9:00 into the Rome field above and the converter shows the matching Tokyo time for today, daylight saving included. It also shows the Tokyo date in case the time crosses midnight.
Yes. It uses your browser's own time-zone data (Europe/Rome for Rome, Asia/Tokyo for Tokyo), which carries each region's daylight-saving rules, so the result stays correct all year.
Yes — press the swap button and the converter flips to show Tokyo → Rome, with the same live clocks and time picker.
It relies on the standard IANA time-zone database built into your browser, not an approximation, and makes no network calls, so your times stay on your device.
