any of you tried the homestay thing instead of hotel?

heard from a friend its fun and cheap! cost like 3k a week if i'm not mistaken, they'll bring you around like tour guides, cook for you, downside is you can't ahem back at their house..

forgot the website he showed me, but google will do the trick.
they've homestay programs all over the world not only in japan

3k is really cheap compared to if you're on your own i think
