I would like the name of a few websites that have Japanese game reviews.

Someone else recommended to me PSPMK2.
http://pspmk2.net/

Recommendations for others would be appreciated.

http://www.famitsu.com/ maybe?
I haven't actually read the site, but it's a popular gaming publication, so I would assume they have reviews on the site.

Actually, they don't. It seems like they want me to have a keitai if I want to look at the reviews.

I read http://game.watch.impress.co.jp/
