wow that's really interesting! Thanks for sharing! I bet those people are thrilled when they learn they can go to an animal shelter and play with the cats all day for free! (at least here you can). Compared to prices of other things in Japan $9 (or $16) is fairly cheap. I went to Tokyo a few years ago and it was almost $10 for a meal an McD's.
