About Iwamizawa Time Zone
Iwamizawa uses the IANA time zone Asia/Tokyo, which is the standard time zone for all of Japan. Its standard offset is UTC+9:00, also known as Japan Standard Time (JST). Japan does not currently observe daylight saving time, so Iwamizawa stays on the same offset throughout the year.
Iwamizawa is located in Hokkaido Prefecture, north of Japan’s main Honshu business corridor, but it follows exactly the same national time standard as Tokyo, Osaka, Sapporo, Nagoya, and Fukuoka. That means there is no time difference between Iwamizawa and Tokyo, even though Iwamizawa is in northern Japan and closer geographically to parts of the Russian Far East than to southern Japan.
Compared with neighboring international time zones, Iwamizawa is 1 hour behind Sydney during Australian Eastern Standard Time, 5 hours ahead of Dubai, 8 or 9 hours ahead of London depending on UK daylight saving, and 13 or 14 hours ahead of New York depending on US daylight saving. This stable non-DST schedule makes Japan relatively easy for long-term planning, but the practical overlap with Europe and North America still changes seasonally because those regions do switch clocks.
