While unfamiliar to many Keio students today—as most rarely have occasion to visit the building—the Jukukan-kyoku is built of brick in the Gothic tradition and located near the East Gate of Mita Campus, between the Old University Library and the Mita Media Center. Over 90 years have now passed since its completion in 1926 by Tatsuzo Sone and Seiichiro Chujo, who also designed the Old University Library, which was completed in 1912.
The word Jukukan-kyoku, again, is not only the name of a building. It also refers to the administrative offices that are responsible for the general affairs of Keio University. The rare name is thought to have derived from the jukukan administrative offices of Tekijuku, Ogata Koan’s school where Keio founder Yukichi Fukuzawa studied as a young man and which would later become Osaka University.
In 1871, Keio University moved from Shiba Shinsenza to its present location in Mita, at the site of the former residence of the Shimabara clan. The earliest instances of the word jukukan-kyoku date back to this same year, when the first Pledges of the Keio Gijuku Shachu, a set of university rules, were printed. These pledges were regularly revised and distributed until around 1897. The book 75 Years of Keio University includes text from the first 1871 Pledges, which details one of the "duties of the Jukukan-kyoku” under a section titled Admission Regulations:
“Article 5: To gain admission to the school, you must provide proof of identity to a professor and receive permission from the Jukukan-kyoku."
From this, we know that even at that time the Jukukan-kyoku helped handle admissions. After the school’s move to Mita, the Jukukan-kyoku’s role grew from admissions to managing dormitories and attendance as well as book lending and other educational affairs, effectively functioning as the administrative arm of the school.
And with the evolution of Keio, the role of the Jukukan-kyoku continued to gradually expand. According to regulations regarding the division of work duties from around the turn of the 20th century, all Keio matters were to be handled through one of three positions: the vice principal, the jukukan (head administrator), or the head of accounting. The position of jukukan was created primarily to oversee administrative affairs and management of the Kishukusha—Keio’s first dormitory. The position came to possess as much authority as the vice principal of education. Eventually, the position of jukukan was eliminated, and in the early 20th century the phrase Jukukan-kyoku came to mean the headquarters of Keio’s administrative offices.
