Tokyo Woman's Christian University Building No. 6 (East Classroom Building): A Campus Building That Grew in Stages
Building No. 6 has the largest footprint of the seven registered structures at Tokyo Woman's Christian University: 1,453 square metres. It did not start that way. The southern portion, from the central entrance down, went up first; the northern half was added later. Look along the facade with that in mind and the building stops being a single object and becomes a record of decisions taken over time.
It was built to house the natural science classrooms. That original purpose explains its position, forward and to the right of the Main Building, fronting onto the courtyard with its face turned west so that it looks directly across at the West Classroom Building.
The construction is reinforced concrete, one basement level and two storeys above, under a tiled hipped roof. The classroom windows are set with steel sash grouped in threes, and that rhythm, repeated along the length of the elevation, is what gives the building its measured, almost procedural quality.
The dating requires a note. The Agency for Cultural Affairs database records the period as Taisho 14, that is 1925, and this article follows that figure as the primary record. The university's own campus guide gives 1927 and adds that portions were extended in 1951 and 1956. The two accounts are not necessarily in conflict, since a building completed in phases can reasonably carry more than one date; readers should be aware that the sources differ.
Why It Was Registered
Building No. 6 is a Registered Tangible Cultural Property (Buildings), registered on 2 September 1998, gazetted on 25 September, in the eleventh round. Its registration number is 13-0029.
The distinction between registration and designation matters here more than usual. Designation, the route to Important Cultural Property and National Treasure status, imposes tight controls appropriate to buildings whose value lies in remaining unchanged. Registration, introduced in 1996, was built for a different situation: modern architecture in continuous use, altered over the years by the ordinary needs of its occupants. A building that gained a north wing after its first completion and was extended again in the postwar decades would sit awkwardly under the older system. Under registration it fits, and it keeps teaching.
The criterion cited is that the building constitutes a model of design. The Agency's commentary notes its original function as natural science classrooms, its orientation facing west toward the West Classroom Building across the courtyard, the phased construction with the north half added later, and the two-storey hipped-roof form with triple steel sash classroom windows.
Antonin Raymond, who drew the 1921 campus plan, is the architect. Born in Bohemia in 1888, he came to Japan in 1919 as Frank Lloyd Wright's assistant on the Imperial Hotel and stayed to build a practice that reshaped modern architecture in the country. Building No. 6 belongs to his early Japanese period, when Wright's manner was still audible in his work but the underlying discipline had become his own.
The university received a BELCA Award in the Long Life Building category in fiscal 1992 for its maintenance of the historic buildings, Building No. 6 included.
What to Look For
Begin at the join. Walk the west elevation from the central entrance northward and watch for the point where the original construction meets the later extension. Concrete of different ages weathers differently, and the alignment of window heads and floor levels tells you where the seam falls even when the surface has been made good. Finding it is a small piece of detective work that changes how the building reads.
The hipped roof deserves a look from the courtyard. A hipped form slopes on all four sides, which gives a heavier, more grounded silhouette than the simpler pitched roofs used elsewhere. Combined with only two storeys above ground, it makes Building No. 6 sit low and wide against the sky, in deliberate contrast to the four-storey Main Building behind.
Count the windows. Three steel sash units to a group here; five across the courtyard at Building No. 7. The Agency's commentary draws this comparison explicitly, and it is the clearest demonstration on the campus that Raymond was varying his handling building by building rather than repeating a formula.
The building is a working classroom block, so interiors are not open to casual visitors. The exterior is fully visible from the courtyard, which is where the design was meant to be seen from anyway.
Getting there: the university accepts general campus visits without prior booking, with registration at the front gate on arrival. Entry is by the front gate only and no visitor parking is provided. From the north exit of Nishi-Ogikubo Station on the JR Chuo-Sobu Line the walk takes about twelve minutes; buses from Kichijoji and Kami-Shakujii serve the Tokyo Joshidai-mae stop.

Q&A
- Why do sources give different construction dates?
- The national database records Taisho 14 (1925), while the university's campus guide gives 1927 with later extensions in 1951 and 1956. The building was completed in stages, which likely accounts for the divergence. This article follows the national record as the primary source.
- Which part of the building is original?
- The section from the central entrance southward was built first. The northern half is a later addition, and further extension work followed in the postwar period.
- What was it originally for?
- It was constructed to house the natural science classrooms. It continues to serve mainly as classroom space today.
- Does being extended reduce its value as a cultural property?
- Not under the registration system. Registration was created for modern buildings that remain in use and change with that use, and it applies lighter controls than designation precisely so that such buildings can continue functioning.
- How does it relate to Building No. 7?
- The two face each other across the courtyard as a pair, with the Main Building closing the view behind. Building No. 6 groups its classroom windows in threes and Building No. 7 in fives, a difference the national commentary specifically records.
