Fascinating Stuff in Japan

A lot of eye openers for me when I went to Japan.
A few things I found out about Japanese life, culture, heritage and technology

1. Japanese toilets are very clean
2. You can wash your bu** when water sprays from the toilet bowl in the toilets when you click a button
3. Their GPS system is very impressive
4. People do not talk in trains, nor do they use their handphones. They do not even make eye contact
5. People there are very friendly
6. They really recycle things there (9 rubbish cans each time)
