Maeda Ikutokukai, Tokyo

The Maeda Ikutokukai foundation is a public interest corporation established on February 26, 1926 for the management and preservation of the cultural heritage of the Maeda clan, rulers of the Kaga Domain. It is located in Komaba, Meguro, Tokyo. The collection is centered on written materials including ancient documents or Japanese and Chinese books but also contains crafts items such as swords, armour or household items. The writings held by the foundation are known as Sonkeikaku library which is also used as an alias for Maeda Ikutokukai. This collection of old books, ancient records and documents is open to researchers on request only. The library's name is derived from the personal book collection of the 5th daimyō of Kanazawa Domain, Maeda Tsunanori, known as Sonkeikaku zōsho, which is distinct from the ancestral collection. ()
