Time in Japan: time zone and time difference

The time in Japan follows Japan Standard Time (JST), nine hours ahead of Coordinated Universal Time (UTC+9). The Japan time zone covers the whole country, from Hokkaido to Okinawa, and there is no daylight saving time, so the clock never changes during the year.

Time difference with major cities

Because many countries change their clocks in summer, the difference with Japan varies through the year. The figures below show how many hours Japan is ahead.

Sydney is ahead of Japan: when it is noon in Tokyo, it is 1 pm in Sydney in the southern winter and 2 pm in the southern summer.

Jet lag

Flights from Europe and North America arrive after a long night, and the eastward shift is usually harder to absorb. Daylight on arrival, a short walk and an early but normal bedtime help the body adjust within a few days. Avoid planning demanding visits on the first afternoon.

Opening hours and the rhythm of the day

• Shops and department stores: usually 10:00 to 20:00.
• Museums: often 9:30 to 17:00, many closed on Mondays.
• Temples and gardens: early opening, closing around 16:30 or 17:00.
• Convenience stores: open 24 hours.
• Last trains: around midnight in big cities, earlier in rural areas.

Dates and the international date line

Flights from North America cross the international date line, so travelers arrive the day after departure, and return flights land on the same calendar day or even before departure time. Check dates carefully when booking the first hotel night.

Keeping track of the time in Japan

Set a second clock on your phone to the Japan time zone before leaving, and use it to schedule calls home. A message sent at 9 pm in New York arrives at 10 or 11 am in Tokyo.

Planning calls and work across the Japan time zone

Office hours in Japan generally run from 9:00 to 18:00 on weekdays. A morning call in Tokyo matches the previous evening in North America and late night or early morning in Europe. For video calls with Europe, late afternoon in Japan corresponds to the morning in Paris or London.

Time on tickets and timetables

Train and flight times in Japan are shown in 24-hour format, and boarding gates close earlier than in some countries. Trains leave exactly on time, so arriving at the platform a few minutes early is the norm.

Japanese dates and calendars

Dates are often written year, month, day, such as 2026/10/19. Official documents may also use the imperial era, Reiwa, which began in 2019, so 2026 corresponds to Reiwa 8. Shops display this format on receipts and expiry dates, so it helps to recognise it. Smartphones switch to the local time automatically on arrival, but alarms set before departure keep the home time, so check them on the first night.
