Japan Standard Time

The city of Akashi in Hyōgo Prefecture is located exactly on 135 degrees east longitude and subsequently became known as Toki no machi (Town of Time).

[8] The two-time-zone system was implemented in Japan between January 1896 and September 1937: From October 1937, Central Standard Time was also used in western Okinawa and Taiwan.

[10] Starting in the late 1990s, a movement to reinstate DST in Japan gained some popularity, aiming at saving energy and increasing recreational time.

Because of this, the sun sets shortly after 19:00 in much of the eastern part of the country (in Tokyo, the latest sunset of the entire year is 19:01, from 26 June to 1 July, despite being at 35°41'N latitude).

Since 2000, a few local governments and commerce departments have promoted unmandated hour-earlier work schedule experiments during the summer without officially resetting clocks.

Japanese former Prime Minister Shinzō Abe made a significant effort to introduce daylight saving time, but was ultimately unsuccessful.

[13] On May 22, 2013, the Governor of Tokyo (then) Naoki Inose proposed a two-hour advance (UTC+11) Japan Standard Time at an industry competitiveness conference.

Eastern part of Hokkaido is over 30 minutes behind and western part of Ryukyu islands is over 30 minutes ahead of local solar time as a single standard time offset of UTC+09:00 is observed in whole country of Japan, even in its easternmost territory, Minamitorishima (153°59′E) and its westernmost territory, Yonaguni (122°56′E). It makes the sun rise before 04:00 at the summer solstice in much of the Hokkaido region and set shortly after 19:00 at the summer solstice in much of the eastern part of the country.
