Time Out says
Located in the former Shinjuku Kuritsu Yotsuya Elementary School, Tokyo Toy Museum exhibits not just Japanese toys, but those from all over the world and is a place for all ages to enjoy. In addition to rooms–former classrooms – dedicated to various categories of toys, from traditional Japanese toys to board games, the museum also houses a museum shop, a relaxation space, and more. The museum clearly welcomes those with smaller children, providing breastfeeding and nappy-changing facilities. Refer to the website for details on the changing round of events and exhibits. There is no on-site car parking, so those who come by car should do a bit of homework ahead of time; local parking spots vary in price, so you might want to hunt around a bit before deciding on a place.
