Started in 1977, International Museum Day “encourages public awareness of the role of museums in the development of society”.
What happens?
To celebrate, many museums in Tokyo — including the Tokyo National Museum, the National Museum of Nature and Science, and the National Museum of Western Art — will have free admission.
This is no secret though, so be prepared for large crowds.
