Tokyo

Japan • Japan Standard Time

Time Zone

Tokyo uses Japan Standard Time (JST), currently running at UTC+9 (year-round). Japan does not observe daylight saving time. JST (UTC+9) is constant every day of the year.

Business & Commerce

Tokyo operates on Japan Standard Time (JST, UTC+9) every day of the year — Japan permanently abolished daylight saving time in 1952, making JST a fixed, predictable offset that never changes across any season. This consistency is significant for international scheduling: you never need to account for a Tokyo DST shift. The Tokyo Stock Exchange (TSE) is one of the largest in the world by market capitalization and opens at 9:00 AM JST. Tokyo runs nine hours ahead of London (during GMT) and fourteen hours ahead of New York (during EST), meaning Tokyo's business day begins and ends while Europe and the Americas are still asleep or finishing the previous evening. This positions Tokyo as the opening anchor of the global trading week — Tokyo's Monday morning is Sunday evening in New York.
