University of Tokyo Library

The University of Tokyo Library is a term used to refer to the University of Tokyo (UTokyo) Library System, which consists of three comprehensive libraries located in each of the university's main campuses, and 27 field-specific libraries affiliated with faculties and institutes within UTokyo. As of December 2023, the UTokyo Library System owns a collection of over 9.98 million books and numerous materials of historical or scientific values, making it the second largest library in Japan. It is only surpassed by the National Diet Library, which stores approximately 12.11 million books.

General Library (Hongo)
The General Library officially opened when UTokyo's predecessor institutions were reorganised to form UTokyo, the nation's first university, on 12 April 1877. However, its roots can be traced back to Edo-era libraries, such as the Bansho Shirabesho. It was relocated to its current location at Hongo in August 1884. Soseki Natsume's novel Sanshiro provides a detailed description of the library around this time.

On 1 September 1923, the original building was destroyed in the Great Kanto Earthquake, along with 750 thousand books from its collections. This loss included over 20 thousand books from Friedrich Max Müller's collections and Takizawa Bakin's handwritten scripts. The library's reconstruction was greatly supported by donations from abroad, the most notable of which was $2 million (about $36 million in 2023) from John D. Rockefeller. "I quite realize that in time the Japanese people will themselves accomplish the complete restoration of their cities and institutions which have been destroyed. However, I shall regard it as a great privilege to be permitted to hasten the day when your University, which stands among the foremost institutions of learning in the world, will again be provided with adequate facilities." This building completed in 1928 is still in use, and it also serves as the headquarters for the whole of the UTokyo Library System.

A major renovation was completed in the late 2010s, and it now features a 46-metre-deep automatic underground storage capable of housing 3 million books.

The General Library is open to faculty members, students, auditors, members of staff, and others who have been approved by the director. Former faculty members, members of staff, and alumni are also allowed access.

ILL service provides access to the holding of the General Library through interlibrary loan of original material. Loan service is available to university libraries in Japan.

Komaba Library
The current Komaba Library, opened in 2002, serves as the successor to the former building, which had become too small for its growing collections. It functions as the main library for the College of Arts and Sciences at Komaba, catering to the general education of all first-year undergraduate students, as well as second to fourth-year students who decided to study there instead of moving to Hongo for specialised education.

The library features a diverse range of learning materials, particularly for subjects such as Linear Algebra and Calculus, which are mandatory for all natural science undergraduates in their first year.

Kashiwa Library
Opened in 2004, Kashiwa Library is a library devoted to the natural sciences. All the books in Kashiwa Library can be searched on OPAC.

Faculty members, graduate students, undergraduate students, auditors, others who have requested use from outside the university, and others who have been approved by the director can use the Kashiwa Library.

Field-Specific Libraries
Apart from the three comprehensive libraries, the UTokyo Library System includes 27 field-specific libraries.
