In an effort to promote freedom of expression, Minato District Library in Tokyo has put on a remarkable display of over 1200 previously banned books. The exhibition showcases the rich history of controversial literature in Japan. Details about why such books were banned, and the societal changes that led to their un-banning, are also included to provide visitors with a deeper understanding of Japan's evolving literary landscape.

The issue of banned books is sensitive in Japan. Some books have been banned due to legal reasons such as copyright disputes, while others have faced restrictions due to their controversial content. A majority of the Japanese population champion the importance of freedom of speech, and view these bans as a limitation of this right. They see the Minato District Library's initiative as an important step towards building a more open society.

In the United States and the European Union, banned books are often the subjects of debate as well. Schools and libraries have been known to remove or restrict access to certain books based on their content. However, "Banned Books Week," a campaign that celebrates the freedom to read, is widely observed. The Minato District Library's initiative mirrors this sentiment.
