I still remember when I was a kid the foreigners always asked me if people wear kimono in Japan still now like Geisha and Samurai.
Yes, people sometimes wear kimono as formal wear or just because they like it.
There are so many things hidden from the foreigners, because there are Uchi (inside) and Soto (outside), as my Australian teacher in my university once said.
Japan is such a weird country, even to my eyes. It has a long long history, and for 200 years it closed the gate to other countries. The 5 most sold newspapers in the world are from Japan, and Japan has the biggest number of bloggers in the whole word.
There are Honne (true feeling) and Tatemae (feeling that you show other people) everywhere.
