In my earlier Blog-post (27 March) I wrote that Japan was one of the few industrialised countries that doesn't join the Daylight Saving Time. But that might change now due to the horrendous earthquake, devastating Tsunami, nuclear disaster in Fukushima Daiichi nuclear plant and the electricity shortness since March 11th. Sony Corp, one of the worlds biggest consumer electronic makers, plans to adopt a Daylight Saving Time system (and other measures) to cut power consumption this summer. This is when the power generation capacity is expected to fall short due to the nuclear disaster. Sony is negotiating with its trade union to move daily working hours to cover a time zone for lower power demand.
Another measure they are planning to take is an enforced 2 weeks summer holiday instead of the 2 days, it is now. This may sound strange for most people, but in Japan the implementation of a law forcing employees to actually take their days off, was necessary to make people do it. And the government did have a point, the Japanese salaryman face a high risk of dying of Karoshi (death from overwork) which is an official cause of death in Japan.
So the big tragedy that has struck Japan, seems to have resulted in some swift "sustainable" changes in the Japanese society. Interesting to see what will happen with those measures when things get back to normal again.
