Not everything was good in Japan, some things were weird, others disturbing, and so on. As it is with every culture, be it your own or not.

1. The cold apartment. Due to humidity issues in the Summer, there’s no isolation to speak of in most Japanese homes. That includes my friend’s apartment. It was dead cold the first two days, then it got better, but sleeping fully dressed isn’t all that nice.
2. The schoolgirl lolita fixation. It’s everywhere, more or less sensual, but everywhere. On magazine covers, in commercials, on posters while riding up the escalators - not to mention all the products that are associated with this weird little thing.
3. The amount of people. Osaka’s got more inhabitants than all of Sweden. I can live with that, but I really don’t want to be among this amount of people all the time. It’s too much in the long run.

Curiously enough, I don’t mind being gaijin (non-Japanese) or having people ogling me all the time.
