This country’s timezone structure

Japan — JST year-round, no DST

Japan runs on Japan Standard Time (JST, UTC+9) year-round across the entire country. DST was tried briefly after WW2 (1948-1952) but abandoned as unpopular. JST is the same offset as Korean Standard Time (KST). Business hours 9 AM - 6 PM formally, with strong presence culture — staying past 7-8 PM is common. Japan's no-DST policy makes cross-Asia coordination unusually clean.

Regional context

Timezones across East Asia

East Asia — China, Japan, Korea, Taiwan, Mongolia — sits mostly at UTC+8 (China's single-timezone policy across the whole country) or UTC+9 (Japan, Korea). None observe DST anymore (Japan ended its post-WW2 experiment in the 1950s), so offsets are fixed. The region's single-large-zone footprint makes cross-Asia coordination unusually easy compared to Europe or North America.
