Have you heard of Anpanman? It’s pretty much a Japanese sensation that every kid loves and knows about as soon as they are born. It’s a toddler/kid favorite and they happen to have a museum called the “Anpanman Museum” in a few locations across Japan.
My daughter is also now into anpanman and we couldn’t wait to take her here. We visited the Yokohama Minato Mirai location and she absolutely loved everything about it. It’s like Disneyland for little kids but it’s not as big and a lot more compact so it’s easier to get around and still tires your little one out :D
There’s plenty of stimulation for your child from shows, things to see, interaction play area, game centers, food, shopping, even kids haircut. The museum is 1500yen per person (for both adults and kids above age 1). Even if you don’t go into the museum though, there’s plenty of free areas just to have fun so it’s totally worth visiting. In fact, the dancing show was the highlight for our daughter and it was in the courtyard which is in the free area so you can keep coming back but not enter the museum part if you’d like.
If you have a young child, this is definitely a fun place to come explore :)
