Some of the best baby facilities are at Roppongi Hills. Not only are there lots of shops, restaurants and cafes, but there are also three nursing rooms and plenty of baby change tables. Highly recommend a visit for an enjoyable stress-free time:)!

My rating: 9/10 (a high rating because of the lovely size of the facilities and the convenience of having 3 options for nursing:) There is also another nursing room on the 6th floor of the Grand Hyatt Hotel)
