Nagoya to Bangkok time difference: the basic math

A 10:00 morning meeting in Nagoya starts at 08:00 in Bangkok. When Bangkok's office closes at 17:00 ICT, Nagoya has already moved into evening at 19:00 JST.

The rule: subtract two hours from Nagoya time to get Bangkok time. Add two hours to Bangkok time to get Nagoya time. That gap never moves.

Why the Nagoya to Bangkok time difference never changes

Neither city changes its clocks. Japan stays on JST (UTC+9). Thailand stays on ICT (UTC+7). No spring-forward, no fall-back.

A call booked for 14:00 Nagoya / 12:00 Bangkok on 15 January works identically on 15 July. The two-hour offset is constant every day of the year.

This makes the Nagoya, Bangkok pair one of the easiest cross-border time differences to manage.

When to schedule calls across the Nagoya to Bangkok time difference

Both cities run a standard office day of roughly 09:00 to 17:00 local time. The two-hour gap creates a generous overlap.

Book meetings in the Nagoya morning. A 10:00 JST start lands at 08:00 ICT, giving you a five-hour shared window until Nagoya's 15:00 / Bangkok's 13:00.

Book meetings in the Bangkok afternoon. A 13:00 ICT start catches Nagoya at 15:00 JST, giving both sides two solid hours before Bangkok wraps at 17:00.

Skip the lunch-hour mismatch. Nagoya's lunch (12:00-13:00 JST) falls at 13:00-14:00 Bangkok time, right when Bangkok's afternoon is underway. Schedule around it.

For remote workers in Bangkok joining Nagoya stand-ups: a 09:00 JST start means a 07:00 ICT alarm. Early but workable. Everyone else can use the core overlap and ignore the gap.

How the Nagoya to Bangkok time difference compares to other Asian hubs

Nagoya is one hour ahead of Singapore and Shanghai, and two hours ahead of Bangkok. See Nagoya vs Singapore and Nagoya vs Shanghai for those figures.

For travellers, the two-hour shift is mild. Flying east to Nagoya loses two hours; flying west to Bangkok gains them back. Adjustment takes a day at most.
