The Building That Was Also a Gate
Kyu Sendai Koto Kogyo Gakko Kenchiku Gakkato (旧仙台高等工業学校建築学科棟), the former architecture department building of Sendai Higher Technical School, stands at Katahira in Aoba Ward, Sendai City, Miyagi Prefecture. Completed in 1930 and owned by Tohoku University, it was entered on the national register of tangible cultural properties on 14 October 2021.
Walk north along Minami-Rokkencho street and the Katahira campus begins with a hole in a wall. The ground floor of this three-storey concrete block is pierced by a barrel-vaulted passage, and for the school that built it, that passage was the front door. The main gate of Sendai Higher Technical School opened onto this street, and everyone entering the grounds passed beneath the vault.
A brick arch frames the opening. Set into it are three letters, SKK, the abbreviation the school used for itself. Students called themselves SKK men. The initials are still there, above head height, easy to miss if you are looking at your phone.
A Concrete Box With European Ambitions
The building went up quickly. Construction began on 7 February 1930 and finished on 4 October the same year, prompted by a Ministry of Education ordinance of 7 April 1930 that established the architecture department. Design came from the ministry's own architecture section; the contractor was Obayashi-gumi of Osaka. School records put the cost at 92,000 yen excluding ancillary work.
The exterior is faced entirely in scratch tile, the roughly combed ceramic cladding that spread through Japanese institutional building in the 1920s and 1930s. Against that surface the architects set long horizontal window bands and let sections of wall project forward. The Agency for Cultural Affairs describes the result as connected to the Bauhaus, and the resemblance is real enough at the level of composition: flat roof, unornamented planes, windows treated as continuous openings rather than punched holes.
The most inventive move is on the east side. Rather than hiding the staircase, the designers raised the stair tower and cut tall windows into it that step upward with the stair itself, so the diagonal of the flights registers on the outside wall. It is a small gesture and it transforms an otherwise rectangular block.
Registration in 2021 came under the criterion of being a model of design, and the property carries registration number 04-0203 from the hundredth round of registrations. The floor area is 480 square metres.
Where Architects Were Trained
The interior was purpose-built for teaching design. Original accounts list three drafting rooms, two general classrooms, four staff rooms, two libraries, a blueprint room and a combined model display and reference room. Corridors ran along the north side on the first and second floors, leaving the south face for the studios, where the light is better. The third floor originally had no corridor at all, just drafting rooms and classrooms opening into one another; it was later brought into line with the floors below.
The department's first head, Ogura Tsuyoshi, taught here throughout its life and built up a collection of models, timber samples, measured drawings and photographic plates that survives today as a designated body of teaching material. Ogura is separately remembered for research on old farmhouses in the Tohoku region and for the postwar reconstruction of Zuihoden, the Date mausoleum lost in the 1945 air raids.
The school itself changed names repeatedly. Founded in 1906, absorbed by Tohoku Imperial University as an attached technical division in 1912, made independent again in 1921, renamed Sendai Technical College in 1944, folded into the new Tohoku University in 1949 and formally closed in 1951. This building carried on as home to the university's architecture department from 1951 until the move to the Aobayama campus in July 1969, after which it stood empty for a period.
It has been in continuous use since. The Research Organization of Electrical Communication occupies it now, listed on campus maps as building G14. The interior was comprehensively renovated in 2002, and in 2014 the scratch tile was replaced and the window frames renewed. Because it is a working research facility, the interior is not open to visitors. The vaulted passage and the exterior can be seen at any time from the public street, and the Katahira campus can generally be walked through, which is worth doing: the same campus holds the former Second High School library stack, the former main gate of that school, and several other registered buildings within a few minutes of each other. Photographing the exterior from the street is unproblematic. The nearest stations are Itsutsubashi on the subway Namboku Line and Aoba-dori Ichibancho on the Tozai Line, five to ten minutes on foot.

Q&A
- Can visitors enter the former Sendai Higher Technical School architecture building?
- No. It is in daily use as a Tohoku University research facility and the interior is closed to the public. The vaulted ground-floor passage, the scratch-tile facade and the stair tower windows are all visible from Minami-Rokkencho street and from within the Katahira campus, which is generally open to pedestrians.
- What do the letters SKK on the arch of the former Sendai Higher Technical School building mean?
- SKK stood for Sendai Koto Kogyo Gakko, the Japanese name of Sendai Higher Technical School. The initials appear on the brick arch at the entrance to the vaulted passage, which served as the school's main gate. Students and alumni used the abbreviation as a name for themselves.
- Who designed the former Sendai Higher Technical School architecture building?
- The architecture section of the Ministry of Education, with Obayashi-gumi of Osaka as contractor. It is sometimes assumed that Ogura Tsuyoshi, the department's first head, was the architect; he taught in the building and shaped what happened inside it, but school records attribute the design to the ministry.
- How do I get to the former Sendai Higher Technical School architecture building?
- It stands at the southern edge of Tohoku University's Katahira campus, facing Minami-Rokkencho street, at 2-1-3 Katahira, Aoba Ward. Itsutsubashi Station on the subway Namboku Line and Aoba-dori Ichibancho Station on the Tozai Line are both within roughly five to ten minutes on foot from the campus.
- Is the former Sendai Higher Technical School architecture building original, or has it been altered?
- The overall form, the vaulted passage and the composition of the elevations survive from 1930. The interior was fully renovated in 2002, and in 2014 the scratch tile was replaced and the window frames changed. The Agency for Cultural Affairs records the 2014 work in its entry. The building retains its original character despite these interventions.
