I have been there a year ago. I went to Nagoya, Tokyo, Kyoto, Hiroshima, Nagasaki, Miyajima. It was amazing trip for me.
I saw lots of temples, gardens, parks. I also went to museums. All places were amazing. Especially Tokyo Ghibli Museum and Kyoto Tezuka's museum. It's important to saw these museums because I love their animations and manga s.
Actually I'm trying to come again. So that I'm trying to learn japanese, and seaching japanese culture.
It's too enjoyful to discover new things about their culture.
