This time I feel something quite different from the feeling that I felt when I traveled in my university days and in my working days. In case it is traveling abroad, I never felt I wanted to go back to Japan even though there was a feeling that I wanted to keep traveling. The term of travel doesn't matter whether it is 10 days or 2 months.
However, this time I feel I'm looking forward to returning to Japan. Traveling and staying are quite different each other. I'll feel like this, "Do I have to go back Japan soon?" even if I traveled for 1 year or 2 years. I think I don't feel same feeling as I'm feeling now.
The reason I mention like this, is that travel is enjoying unordinary life not daily life, I mean, enjoying unreality. Therefore, if I live there, it's not unreal, it's "real", daily life, and Japan becomes "unreal". In short, this is the reversal of "reality" and "unreality".
