Tokyo and Seoul are in the same time zone. When it's 3:00 PM in Tokyo, it's also 3:00 PM in Seoul. Both cities use UTC+9 and neither observes daylight saving time.
This makes business coordination between Japan and South Korea extremely convenient - no time zone math required!
Any time works! With no time difference, standard business hours of 9:00 AM - 6:00 PM work perfectly for both cities.
Tokyo and Seoul are connected by flights of about 2.5 hours, making same-day business trips feasible. Both are major Asian tech and entertainment hubs with extensive K-pop and J-pop cultural exchanges.
