Survival Japan - Sunshine

What does sunshine have to do with survival? Possibly everything. Major earthquake striking at dark cause more problems for rescue work than in daylight. The lack of twilight in summer really threw me off last summer. It seemed like it was dark 15 minutes after sunset. Don't expect a long evening sipping beer on a terrace in July chatting while the sun goes down; it's over at 19:00. Sure, there is more daylight now in winter in Tokyo, but it's too cold to be thoroughly enjoyed like in the Netherlands:

As you can see in the graphs of the linked website, the differences between Amsterdam and Tokyo don't appear to be that big. You can clearly see the moment the Netherlands switches to daylight saving time, and the effect it has on daily sunshine hours. You could of course get up at 4 am in summer to catch those extra rays. The worst time for an earthquake here during summer is between 19:00 pm and 04:00 am, depending solely on darkness. Considering traffic flows however, less people would be affected during night time as they are still at home, rather than travelling on raised highways or through deep subways. Still, not all homes are earthquake proof, and many older people sleep on the more easily collapsing ground floor of their house. Naturally, the best time for an earthquake is never, but that's just not the kind of world we live in.
