Thanks for your advise, I have better than mangas, I got a Japanese wife ^^ but, it is sill difficult to be motivated to learn the language and improve it. I am good a listening but not speaking.
I studied a Shinjuku, it was quite fun, except that I was the only european guy, so... all the other asian people were making progress so fast, but not me !
Where are you living in Japan ? Do you work there ?
