Miscellaneous things about Tsukuba and Japan (6)

It's time for the next installment of "Miscellaneous things about Tsukuba and Japan"! I thought that there's not really many things to surprise me any more, but I guess I'm wrong.

Electronic light switch
I've seen this for quite sometimes now, but only recently realized what it implies. Some light switches in Japan are not mechanical, but are electronic. By removing the mechanical part, we've opened up a wealth of possibilities, such as light control and monitoring from a remote location. I'm not sure how much of that is actually implemented, but it's interesting nevertheless.

Ground wires
This one is also electrical, though I don't like it too much. A lot of Japanese homes and buildings are not wired up for ground, so some electrical appliances make the ground "optional" by doing this...

Election Posters
Unlike Thailand where you'll be able to find election posters virtually everywhere before an election, posters are more regulated in Japan. A billboard was setup in various places and the candidates may only post their posters on the allocated space on the billboard. Other kinds of campaigns such as brochures, speeches and TV ads still exists though.

Coin exchange
Following the Japanese style of "If a machine can do it, a machine will do it", game centers don't have coin exchange staffs but rather have machines to do the job. I must say though that Japanese machines are very adept at handling money, being able to accept banknotes and multiple coins at once.

Train air-conditioning
This is more or less "attention to the details". On the Tsukuba Express line, the third car has the air conditioning set to lower power for people who do not like cold air.
