☀️❄️ Changing to winter time / summer time

All of those who already traveled in Japan have noticed that unlike many countries, Japan does not change to summer time or winter time.

As a matter of fact, until Meiji era (1868-1912), every regions of Japan had their own "time zone" determined by the sun zenith. When train 🚅 transportation started to develop, the time differences were inconvenient (a train departing from Tokyo arrived in Osaka 20 minutes before its departure hour) so in 1886 an ordinance was issued to implement a nationwide standard time.

In the beginning of the 20th century, several countries of the northern hemisphere started to use the daylight saving time, mainly to save energy (they are more than 70 countries nowadays). However, some countries do not use this system, such as Japan where the summer time is not implemented. Or more precisely, summer time was only used during the U.S. occupation between 1948 and 1951, and was never reintroduced, despite some debates.

Among the OECD countries, Japan, South Korea and Iceland are the only 3 countries not to implement the daylight saving time system, which can make their time difference with the rest of the world a little bit difficult.
