A 1928 Schoolhouse on the Grounds of Kariya Castle
The Kariya City Local History Museum keeps its collection inside a building that began as a school. Completed in October 1928, it was the main hall of Kijo Ordinary Higher Elementary School, and it still stands in the Shiromachi district of Kariya, Aichi Prefecture, on land that once lay within Kariya Castle. The castle's older name, Kijo, meaning "turtle castle," passed to the school and to the surrounding park, which is now Kijo Park and well known locally for its spring cherry blossoms.
That name trips up first-time visitors. The characters 亀城 can be read Kameshiro, but here they follow the castle and are read Kijo. The reading is the older one, tied to place rather than to the literal sound of the characters.
The Architect and What He Built
The design is the work of Onaka Hajime (1886 to 1950). Born in Kumamoto and trained in the architecture department of the Fukuoka Prefectural Industrial School, he spent time at the Yawata steelworks before joining the building section of the Aichi prefectural government in 1908. During those years he handled school buildings that survive today as two prefectural high schools in Kariya. In 1924 he left the prefecture, opened his own office in the town, and worked for the rest of his career on schools, clinics and houses across western Mikawa and out toward the Chita Peninsula. Among all of this, the Kijo main hall is usually singled out as his defining building.
Onaka had a second life as a haiku poet under the pen name Onigawara, and he wrote a verse for the school's sixtieth anniversary in 1933. It is a small reminder that the building came from a designer with a foot in the arts as well as in engineering.
The structure repays a close look, partly because the records do not fully agree. The Agency for Cultural Affairs lists the building as reinforced concrete, and the columns, beams and outer walls are poured concrete. The detailed description prepared for the national register adds a wrinkle: the floors and the roof rest on a timber roof frame, which makes the building a concrete-and-wood hybrid rather than a pure concrete frame. Its footprint measures 748 square meters, and the roof is laid in tile. For a provincial town in the late 1920s, a concrete school of this scale marked an early step in the spread of the material beyond the big cities.
What to Look For
Stand in front and the composition explains itself. The facade is symmetrical around the central entrance, but the two end wings push forward well past the porch, each showing a broad gable. That habit of throwing the ends forward of the center draws on the Baroque line of Western architecture, filtered through a Japanese schoolhouse. The entrance porch carries buttresses, and the pilaster shapes along the walls are cut to form the katakana character "ki," the first sound of Kijo and a quiet nod to the castle name.
The plan is a single-corridor type. Classrooms run along the south side, the corridor along the north, and the projecting ends held the special classrooms. Because those ends jut forward, the corner rooms could have turned out awkwardly large, so Onaka set staircases at both ends of the corridor to widen it and even out the room sizes. The result keeps the architectural gesture without sacrificing the school's working plan, one reason the building is read as his best.
Inside, eight exhibition rooms hold farm tools, folk implements and material connected to Kariya Castle. A recreated classroom and a recreated home from the 1950s let visitors step into the postwar decade, and on Saturdays, Sundays and public holidays there is a weaving activity where you can make a small coaster-sized piece by hand.
Saved by Its Graduates
By the 1970s the building had done its work. A new school block went up in 1974 and a special-classroom wing followed in 1977, after which the old main hall sat empty. The city drew up plans to pull it down. Graduates and local cultural figures pushed back, campaigning to keep the building, and their effort won out: in 1980 it reopened as the city museum. In 1999 it became the first property in Kariya to be listed as a national Registered Tangible Cultural Property, recognized for its contribution to the historic landscape, and a 2011 renovation added the recreated Showa-era rooms.
Admission is free. The museum has no car park of its own, so drivers use the Kijo Park lot next door and walk in past the castle grounds.

Questions and Answers
- Why is it read "Kijo" when the characters are 亀城?
- 亀城 (Kijo, "turtle castle") is the old alternate name of Kariya Castle. The school was named after the castle, so the reading follows the castle: Kijo, not Kameshiro.
- Is this the original building, and can I go inside?
- Yes. The 1928 main hall is preserved and open to the public as the city museum, with eight exhibition rooms. Admission is free.
- How do I get there?
- It is about a 20-minute walk from Aizuma Station on the JR Tokaido Main Line. The Karimaru community bus (Aizuma line) also stops at Tsukasacho 4-chome, five minutes on foot from the museum.
- Is there anything to see besides the architecture?
- The eight rooms display farm tools, folk implements and material on Kariya Castle, plus recreated 1950s classroom and home interiors. A hands-on weaving activity runs on weekends and public holidays.
- When was it built, and who designed it?
- It was completed in October 1928 and designed by Onaka Hajime, an architect who ran his own office in Kariya. The building is regarded as his signature work.
