About Tokyo Time

Tokyo operates on Japan Standard Time (JST), which is UTC+9 year-round. Japan stopped observing daylight saving time in 1951, so the offset remains constant throughout the year — a helpful simplification for international scheduling.

The Tokyo Stock Exchange (TSE) is the largest in Asia by market capitalization. Morning trading runs from 9:00 AM to 11:30 AM JST, with an afternoon session from 12:30 PM to 3:00 PM JST. The lunch break is a distinctive feature of Japanese markets.

Tokyo is 1 hour ahead of Singapore and Hong Kong, and 14 hours ahead of New York (EST). This makes early-morning meetings in Tokyo a practical option for connecting with US-based colleagues at the end of their workday.
