Japan and China sites

Can anyone recommend me good Japanese and China sites that has great UX and UI. Preferably anything related to shopping or lifestyle. Thank you.

Japanese design, you say? http://www.muji.com
Check out Behance for inspiration. There are quite a few talented Asian designers on there.

I like this site for Japan:
