I am so impressed with nursing rooms in Japan. They are really cozy and functional. Usually, there are diaper changing tables and private breastfeeding rooms. Some places have hot water tanks, microwaves and vending machine which sells diapers and baby foods. If you have chance to go to public place such as shopping mall, highway service area and airport with baby, Check this out!! Here is pics.
