Sanrio Puroland, Tama

Weekday tickets start at 3,300 JPY for adults, rising to 3,800 JPY peak. Features include the Lady Kitty House cosplay area, musical shows, and meet-and-greets with Hello Kitty, My Melody, Cinnamoroll, and Pompompurin. TripAdvisor calls it ‘maximally kawaii.’ Located 30 minutes from Shinjuku on the Keio Line (480 JPY), it’s an ideal half-day excursion. Unlike aquarium animal exhibits, it provides 20% more indoor play areas for children aged 2-10, focusing purely on whimsical fun.
