If you follow any Japanese culture site like Kotaku East, you’re going to find out about a lot of really specific and very cool looking museums and theme parks. They’re laser-focused as a rule and really cool looking.
The Totoro House is the best I’ve stumbled across so far. It’s a life-size recreation of Hidaka and Sakamoto’s house from My Neighbor Totoro. Everything is there, from the stacks of books in the library to the sandals placed underneath the porch.
It’s a nostalgia trip to look through the tourist photos you can find online. Kotaku East has a huge gallery that just made me smile. The incredible level of detail will take your breath away.
