 note = {pdf, The UCLA Toganoo collection consist of Buddhist texts collected by scholar of Shingon Buddhism Toganoo Shōun 栂尾祥雲 (1881〜1953) who had held positions of director of Kōyasan University Library, president of Kōyasan University and The Institute of Esoteric Buddhism. The collection is made of pre-modern Japanese esoteric Buddhism texts and books published after 1868. 
Dean of The Department of Oriental Languages of UCLA, Enshō Ashikaga 足利演正 took the lead in purchasing the collection from 1962 to 1963 through Shōzui 祥瑞, son of Shōun. The department needed to improve Buddhist texts in Oriental Library at that time for the establishment of a course on Buddhism. 66 texts selected among around 110 pre-modern Japanese texts are published in a facsimile edition, Toganoo Collection Kenmitsu Tenseki Monjō Shūsei, published by Hirakawa Shuppansha.
However, the compilers of the facsimile edition had not take any notice about the collectors seal and signatures of ownership on covers of the woodblock printed books and manuscripts of the whole collection. That valuable bibliographical information is also omitted in the Catalog of Rare Japanese Materials at the University of California, Los Angeles compiled by Jun Suzuki and Mihoko Miki and published by Tosui Shobō in 2000. 
My research for 10 days in East Asian Library in this year revealed that the collection contains a lot of information about the formation, the accumulation, and the utilization of Buddhist texts in temples in pre-modern Japan. Above all, collectors seal and signature of Kakujōin 覚城院 in Mitoyo city, where Shōun served as chief priest, and temples located in neighboring city show a relation with Kazumaro Nakayama 中山一麿 as a representative conducts “Protection and maintenance of library in Kakujōin for basic research”. 
The collection contains several texts formerly owned by Kakujōin like Daibirushana jōbutsu kyō sho 大毘盧遮那成仏經疏, whereas collector seal of Ishana-in, located in same city, appear on the first page of the text. It is also confirmed that ownership seals and signatures of Honzanji 本山寺, Konkōji 金光寺 in the same Mitoyo city, Hōzenji 宝善寺 in Sanuki city, Sairenji 西蓮寺in Shikokuchūō city Ehime Prefecture, Jippōji 實報寺 in Saijō city、Nariaiji 成相寺in Miyazu city Kyōto, Hōmanji 宝満寺 in Ayabe city, Eifukuji 叡福寺 in Taishi city Osaka, Enmeiji 延命寺 in Kawachinagano city are marked and written down. 
Those bibliographical informations reminds us that priests practicing Buddhism study used to read the texts come to Shōun’s hands later. Signature and seal of Chūdō 仲道 served the chief priest of Kakujōin also appear as former owner on the texts. These texts seemed to hand down to shōun through study of esoteric Buddhism. 
The books published after 1868 also deserves attention as historical documents of international relationship of Buddhists in Kōyasan, including an autographed volume of a book written by Beatrice Suzuki.},
