What UTC offset does Tokyo use?

Tokyo uses Japan Standard Time (JST), which is UTC+9 year-round. Japan abolished daylight saving time in 1952 and has not observed it since. This fixed offset makes Tokyo one of the easier Asia-Pacific cities to schedule with, as its relationship to other time zones never changes seasonally.

What are typical business hours in Tokyo?

Standard business hours in Tokyo run 9 AM to 6 PM JST, Monday through Friday. Japanese work culture historically emphasized long hours, and many employees stay until 8 or 9 PM. However, government-mandated work reform initiatives have pushed companies toward earlier finishes. Core decision-making hours are generally 10 AM to 5 PM JST.

What is the best time to schedule a call between Tokyo and New York?

Tokyo is 14 hours ahead of New York (EST) in winter and 13 hours ahead in summer (EDT). The only workable overlap is early morning New York time meeting Tokyo’s late afternoon. A 7–9 AM EST call is 9–11 PM JST, which asks Tokyo to stay late. Alternatively, a 7–9 PM EST call is 9–11 AM JST the next day, often the preferred arrangement.
