In the summer of 2020, Tokyo will once again host the Olympic and Paralympic Games. It's the first time the Paralympics will be hosted by a city for the second time.

More than half a century has passed since Tokyo last hosted the games in 1964. It's a very different city than it was back then. Many train and subway stations in Tokyo now have elevators and an increasing number of facilities have special bathrooms that can be used not only by those in wheelchairs but also parents wanting to change their babies' diapers.

There is high expectation the Tokyo Games will be an opportunity for the city to become truly barrier-free — both physically and emotionally.
