A gravestone shop I pass on the way from the hotel to the supermarket offers cute gravestones as an alternative to the traditional obelisk variety. I asked, and they're not just for decorating your Japanese garden. Couldn't bring myself to ask if they actually got permission from Sanrio and Disney for these, though. It didn't seem polite.
They're about 140,000 yen each, and look like they were computer-carved from a smaller doll. The Kitty actually has a bow in contrasting red granite, and an actual hoodie, much like Degas' Dancer has an actual tutu. Yes, I just compared Hello Kitty to Degas.
