What is the time difference between Tokyo and Ho Chi Minh City?

Tokyo (JST, UTC+9) is always 2 hours ahead of Ho Chi Minh City (ICT, UTC+7). Neither Japan nor Vietnam observes Daylight Saving Time, so the gap is a fixed 2 hours every day of the year.

Does the Tokyo to Ho Chi Minh City time difference ever change?

No. Japan (JST, UTC+9) and Vietnam (ICT, UTC+7) both use fixed UTC offsets with no Daylight Saving Time adjustments. The 2-hour difference is constant throughout the year.

JST stands for Japan Standard Time. It is UTC+9 and is used across all of Japan year-round. There is no Daylight Saving Time in Japan.

ICT stands for Indochina Time. It is UTC+7, used across Vietnam, Thailand, Laos, Cambodia, and parts of Indonesia year-round. There is no Daylight Saving adjustment in any of these countries.

What are the best meeting times for Tokyo and Ho Chi Minh City?

Since Tokyo is 2 hours ahead, a 09:00 Tokyo call lands at 07:00 in Ho Chi Minh City — slightly early. A 10:00–17:00 Tokyo window maps to 08:00–15:00 in Ho Chi Minh City, giving a comfortable overlap for business hours in both cities.

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 do automatically.

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.
The same moment is converted to Asia/Ho_Chi_Minh time (ICT, UTC+7).
The UTC offsets are compared: Tokyo is UTC+9, Ho Chi Minh City is UTC+7, giving a fixed +2 hour gap.
All values — Tokyo time, Ho Chi Minh City time, and the offset — refresh every second.
Because neither country uses Daylight Saving Time, the 2-hour gap never changes.
