Current time in Tokyo

Frequently asked questions

Common questions about Tokyo's time zone, daylight saving rules, and scheduling across it. Can't find what you need? Email [email protected].

Does Tokyo ever change its clocks for daylight saving?

No—Japan hasn’t used daylight-saving time since 1951, so Tokyo’s UTC+9 offset is the same in every season.

How does Tokyo’s single time zone work across all of Japan?

Japan spans roughly 30 degrees east–west in longitude but runs exclusively on Asia/Tokyo, so the sun can rise almost an hour earlier on one side of the country than the other.

Why is JST important for Asia–Pacific business?

Tokyo is the world’s largest metropolitan economy by GDP; many regional deals, forex trades, and tech launches are timed to its market hours, setting the pace for the broader UTC+8 to UTC+10 corridor.

What’s a good overlap window between London (GMT) and Tokyo (JST)?

The best shared working hours are roughly 08:00–09:00 London time (17:00–18:00 Tokyo time), giving just one solid hour before the UK heads home for the evening.

When does the sun rise and set in Tokyo during summer?

Around the summer solstice, sunrise is as early as 04:25 and sunset near 19:00, giving office workers almost 15 hours of daylight without any clock change.

When does the sun rise and set in Tokyo during winter?

In late December, sunrise shifts to about 06:50 and the sun sets around 16:30, shaving the day to just under 10 hours of daylight, yet work hours stay the same.

Is there daylight-saving pressure in Japan?

Politicians occasionally debate adopting daylight saving to cut energy use or boost tourism, but public resistance and strong business status-quo bias have kept clocks unchanged for decades.

How does Tokyo’s year-round JST help remote teams?

With zero offset shifts to track, you can set recurring meetings once and forget them—ideal for global sprints, stand-ups, and release schedules that involve Japanese partners.
