Summertime debate in Japan

Suddenly, at least for me, the introduction of summer time was suggested by Abe Shinzo, the Prime Minister of Japan.

Japan is located more southern than many European nations. Therefore, the effect of daytime saving is not expected for summer time. Instead, Abe
seems to intend to reduce the burden of athletes in Tokyo Olympic planed in 2020. It is extremely hot in the summer in recent years. If the time clock is shifted, we might avoid the hottest time. Indeed, some researchers hypothesize the introduction of summer time will save much cost for electricity.

On the other hand, starting summer time is very problematic. In my opinion, it is ridiculously infeasible.

First, shifting clock needs entire replace of electric systems. Its cost will be astronomical. European nations introduced summer time several years ago before many IT devices were spread.

Second, shifting time causes health risks. Abe intends to shift the clock by two hours. Thus, citizens have to wake up two hours early. It will be burdening a lot. Several reports suggest many people feel sick on the day of shifting.

Third, the economic effect is doubtful. Introducing summer time only for the Olympic is completely absurd. On the other hand, the annual introduction of summertime has little impact on our lives because sunshine is continuous for a long time in summer.

I expect the Prime Minister to abandon this silly idea.
