About the library:

The Toshiba Library began in 1982 when the Law Library at Columbia University received a donation of over 13,000 items from the family of the late Justice Jiro Tanaka. This original collection was a comprehensive overview of Japanese law, with a concentration on constitutional law. It is currently considered one of the most comprehensive collections of Japanese law outside of Japan.

Approximately 40% of the collection is located in the open stacks of the library; the remaining 60% are in storage or the closed stack area, and are available on request.

For more information on the Japanese collection, please call 212-854-4193 or email the curator.
