[Books Set in Japan?]

This is actually a question from my sister who asked me if I knew of any books set in Japan and I couldn't think of any!

 

Then I remembered I knew the perfect place to find recommendations for any kind of book

 

She particularly likes romance, historical fiction, fantasy and YA but all recommendations would be appreciated

 

(She has already read Memoirs of a Geisha)

Tokaido by Lucia St. Claire Robson ,
