A 27-Year-Old's First Building, Built in 1932
On a quiet street in Hirosaki called Zaifu-cho, where the wooden gates and earthen walls of former samurai residences still set the tone, a flat-roofed white box of reinforced concrete sits among the old houses. This is the Kimura Industrial Research Institute, completed in 1932. It was the first building the architect Maekawa Kunio ever saw constructed, finished when he was twenty-seven and barely back from two years in Paris.
Maekawa had just spent that time in the atelier of Le Corbusier, the Swiss-French architect whose ideas were reshaping how the modern world thought about buildings. He was the first Japanese to work directly under Le Corbusier, and the Hirosaki commission gave him a chance to put what he had absorbed into concrete and steel almost immediately.
The building's reach into Hirosaki was personal. Maekawa's mother came from the town, her family having served the local domain as samurai, which is one reason the architect would return again and again over his career to leave eight separate works across the city.
The Commission That Crossed an Ocean
The man who paid for the building, Kimura Ryuzo, was a military attaché at the Japanese embassy in France. He and Maekawa became friends in Paris, introduced through the architect's diplomat uncle. Kimura had a purpose for his hometown: he wanted to set up a research body to strengthen local industry in the Tsugaru region, carrying on a wish his own grandfather had held for the area's economic life.
Maekawa is said to have worked on the design during the long sea voyage home. What arrived in Hirosaki was unlike anything around it. Where the neighbours showed timber, tile, and pitched roofs, the new institute presented flat white walls, a roofline cut straight across the sky, and windows stretched into long horizontal bands.
The building drew notice from far beyond Aomori. When the German architect Bruno Taut passed through Hirosaki during his years in Japan, he saw the institute in person and recorded it in his writing on Japanese architecture, an early sign that this small provincial commission carried weight.
Why It Became an Important Cultural Property
The Agency for Cultural Affairs designated the Kimura Industrial Research Institute an Important Cultural Property on August 2, 2021, under the criterion for high historical value. The reasoning is straightforward: this is among the very earliest buildings in Japan to give physical form to the modernist principles Le Corbusier had set out.
Several of those principles are visible at a glance. The structure rests in part on pilotis, the slender columns that lift a building off the ground and free the ground floor. The walls carry continuous horizontal windows rather than the punched openings of older construction. The supporting columns stand clear of the outer walls, so the facade no longer has to bear the weight, and a curved wall pushes out from the otherwise rectangular volume to break the straight lines.
The path to this designation was gradual. In 2003 the institute became the first of Maekawa's works to be listed as a Registered Tangible Cultural Property. The following year it was chosen for the DOCOMOMO Japan selection of significant modern buildings. The 2021 elevation to Important Cultural Property placed it in the country's top tier of protected architecture.
What to Notice Inside and Out
From the street the building reads as restraint: white surfaces, horizontal lines, a balcony, and steel-framed sashes holding wide panes of glass. Step into the entrance hall and the mood shifts. The ceiling opens into a double-height void, and Maekawa painted it red, so the bright glazed interior carries a sudden jolt of strong colour overhead.
Two small details reward a slow look. In the first-floor reception room, the window sashes follow a gentle curve and the columns are turned round rather than square, a softness rare in early concrete buildings. In the first-floor restroom, the door handles are fitted with crystal knobs, a sign of how far the young architect's attention reached.
That attention extended past the structure itself. Maekawa designed the chairs, desks, and shelves used in the offices, treating the building and its contents as a single composition rather than a shell to be filled later.
A Building Still at Work
The institute has never become a museum piece behind a rope. It is the home of the Hirosaki Kogin Institute, which carries on the kind of local-industry work the original founder intended.
Kogin-zashi is a counted-thread embroidery from the Tsugaru region. Its origins lie in hardship. In the Edo period, farmers here were permitted to wear only hemp, never cotton, and hemp did little against the long Aomori winter. Women began running cotton thread through the open weave of the cloth to add warmth and strength, counting odd numbers of threads as they stitched, one, three, five, seven, and from that counting the dense geometric patterns emerged. Around forty base motifs, called modoko, are combined into the larger designs.
The Hirosaki Kogin Institute began in 1942 as a homespun-textile company and went on to study and revive the technique. Visitors can see the workshop, watch the stitching, and buy pieces made entirely by hand. Hands-on coaster-making sessions are sometimes offered, though they have been paused at points, so it is worth checking ahead if that is your aim.
Around the Building
Hirosaki rewards anyone interested in modern architecture, because Maekawa's career can be traced through the city in sequence. After this 1932 debut came the Hirosaki City Hall (1958), the Hirosaki City Hall auditorium and the Civic Center (1964), the Municipal Museum (1976) inside Hirosaki Park, and his crematorium (1983), among others. The works sit within cycling distance of one another, and a slow loop between them, with coffee stops along the way, is a recognised way to spend a day here.
The institute also stands close to Hirosaki Park and Hirosaki Castle, the town's best-known sight and one of the country's great cherry-blossom destinations in spring. The Zaifu-cho district around the building was home to figures such as the Meiji journalist Kuga Katsunan, and its older streetscape makes the short walk to the castle grounds part of the experience.

Q&A
- Can I go inside the building?
- Yes. The ground floor houses the Hirosaki Kogin Institute, which welcomes visitors during its opening hours and lets you see the workshop and the entrance hall. Admission is free. Because it is a working institute rather than a museum, calling ahead is recommended, and group visits in particular should be arranged in advance.
- When is it open?
- The Hirosaki Kogin Institute is generally open from 9:00 to 16:30 and closed on Saturdays, Sundays, and public holidays. Hours can change, so confirm before a special trip. There is parking for about five cars.
- Why is a 1932 building considered so important?
- It is one of the earliest buildings in Japan to apply the modernist ideas of Le Corbusier, designed by Maekawa Kunio right after he trained in Le Corbusier's Paris atelier. As Maekawa's first completed work, it marks the starting point of a career that helped define Japanese modern architecture.
- What is kogin-zashi, and can I try it?
- Kogin-zashi is a traditional counted-thread embroidery from the Tsugaru region, originally stitched by farming women to reinforce and warm hemp clothing. The institute sometimes runs short coaster-making workshops, but availability varies and sessions have been suspended at times, so check current information before planning around one.
- How do I get there from Hirosaki Station?
- It is roughly a 14-minute taxi ride or about a 35-minute walk from JR Hirosaki Station. By local bus, you can ride toward the university hospital, get off near the hospital stop, and walk a few minutes. The building sits near Hirosaki University Hospital in the Zaifu-cho district.
