Yes Book Off actually has 2 shops in Paris, a big one for Japanese books and a small one for French and English books.
Thanks for the recommendations. I'll look into them next week.
Actually, I forgot that I do read modern Japanese fiction. I like the samurai detective stories by 池波正太郎, especially the series 剣客商売 and 鬼平犯科帳.
There is going to be a trade fair of e-book readers in Shenzhen next year on March 16th. This is the link:
