About this tool
Convert time between Hong Kong 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 Hong Kong — this converter shows both cities' clocks live and the exact current time difference between them, adjusted automatically for daylight saving. Hong Kong runs on the Asia/Hong_Kong zone (HKT) 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 Hong Kong time to pin the matching Tokyo time, or press swap to convert the other way. Nothing is uploaded.
Open Hong Kong to Tokyo Time Converter on AltFTool — it loads instantly in your browser.
Read the live clocks at the top for the current time in Hong Kong and Tokyo.
Type a specific time into the Hong Kong field to see the matching Tokyo time and date.
Press swap to convert Tokyo times to Hong Kong instead.
The current local time in Hong Kong 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 Hong Kong 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. Hong Kong uses Asia/Hong_Kong and Tokyo uses Asia/Tokyo.
Type 9:00 into the Hong Kong 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 (Asia/Hong_Kong for Hong Kong, 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 → Hong Kong, 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.
