Hello!
Thank you for your questions.
1. Because of hard working people, tasty food, beautiful country and beautiful landscape. Japan has very good city infrastructures and is very good organized country.
2. Oh it's a difficult question. There will be surely a surprise.
3. Yes, unfortunately only a few Japanese speak good English. Maybe it's because there isn't lot of possibility or encouragement to use English. If everything is written in Japanese, so it doesn't make it easy.
4. Yes, I think because of globalisation.
5. From 2007 till 2008 I have only experienced a few troubles in Japan. But at the beginning of 2009 I experienced more troubles. I spent many weeks in
Kyushu island and in Fukuoka people came very close to me and coughed very loud. It was all the time like this there. Even in the big shopping centres and supermarkets, the sales staff coughed when they saw me entering. I felt I'm not welcome in Kyushu (Fukuoka, Kumamoto, Kagoshima...). Some bicycle drivers spewed in front of me and this happened in Tokyo too. Meanwhile I experienced troubles in Tokyo too.
I'm used to walk alone in Japan. So, friends who walk together told me they don't experience this kind of problems.
6. I think it's not possible in all Asian countries. It's because of culture, tradition and history.
Thank you for your interesting questions.
