Japan uses Japan Standard Time (JST), IANA identifier Asia/Tokyo.
Japan Standard Time applies to the entire country, including Okinawa, and is aligned to the 135° E meridian near Akashi.
Japan has not observed daylight saving time since the late 1940s, so JST is a constant UTC +09:00.
The second panel shows UTC beside the local clock, and the roller lets you check any UTC hour against JST — useful when a call, deadline or flight time is published in UTC.
