A Laboratory Building Named for the Man Who Made Japanese Steel Famous
Honda Memorial Hall (本多記念館, Honda Kinenkan, part of the Institute for Materials Research known in Japanese as Kinken) is a reinforced concrete research building on the Katahira campus of Tohoku University in Aoba Ward, Sendai, completed in 1941 and entered on Japan's register of Tangible Cultural Properties on 14 October 2021.
The building carries the name of Kōtarō Honda, the metallurgist who founded what is now the Institute for Materials Research and served as the sixth president of Tohoku Imperial University. Honda developed KS magnet steel in 1917, an alloy with a coercivity far beyond anything then available, and the discovery put a Japanese laboratory at the front of international materials science for the first time. A committee formed to mark his twenty-fifth year at the university raised the funds and built this hall.
It stands three storeys above ground with one below, covering 689 square metres. That footprint is modest by the standards of a modern research institute, and the building has never stopped working: it now houses offices, meeting rooms, a technical consultation service and accommodation for visitors, alongside its two exhibition spaces.
Reading the Facade
The exterior is deliberately plain. Tile-clad walls carry pilasters that push the vertical rhythm forward, and rectangular windows sit between them in even ranks. There is almost no ornament, which was itself a position in 1941, when Japanese institutional architecture was moving away from the eclectic historicism of the previous generation toward something stripped and rational.
One element breaks that restraint. Above the entrance, a large canopy projects forward over the carriage porch, cantilevered out far enough that it reads as a separate gesture from a distance. It is the only part of the composition that announces itself.
Step inside and the material changes. The entrance hall is finished in marble, and the finish continues into a stairwell built on an elliptical plan, so the flights curve rather than turn at landings. Anyone who has walked up a rectangular institutional stair will register the difference immediately in the way the handrail moves under the hand.
The Agency for Cultural Affairs registered the hall under the criterion covering buildings that contribute to the historical landscape of the country. The description filed with the registration notes that the clear, unfussy design expresses the character of its period.
Renovation work in 1994 reinforced interior walls and updated the fittings. Sendai's tourism authority records that the marble around the entrance hall and stairs was preserved during that work, which is why those surfaces still read as original.
Seeing the Building, and What Is Inside
Katahira is an open campus. The grounds can be walked freely, and the exterior of Honda Memorial Hall can be seen at any time without an appointment. Photographing the outside is unproblematic; the building sits on a public university campus rather than behind a gate.
The interior is a different matter, since this is an active research facility. Two rooms are set up for visitors: the Honda Memorial Room, which holds laboratory notebooks, photographs and personal effects left by Honda himself, and an adjoining exhibition room displaying materials the institute developed, KS permanent magnet steel among them. The Institute for Materials Research asks that anyone wanting to see these consult its permanent exhibition page and arrange a visit in advance.
The wider campus rewards the walk. Katahira has been a place of higher education since the Second Higher Middle School opened here in 1887, and several of its buildings hold the same registered status. Tohoku University Gallery Historia occupies the ground floor of the former Faculty of Science biology building, itself registered in 2021, and opens on Tuesdays and Thursdays from noon to four, free of charge, with displays covering the campus's registered architecture. The university archives, holding Honda's research notebooks and a signature left by Einstein during his 1922 lecture tour, are also on site.
Katahira campus received a special award in the 2017 Urban Landscape Grand Prize, the first university campus to be recognized in that programme. Sendai Station is about twenty minutes away on foot, or a short ride on the Namboku subway line to Itsutsubashi.

Q&A
- Can visitors go inside Honda Memorial Hall?
- The exterior can be viewed freely, since Katahira campus is open to the public. The Honda Memorial Room and the adjoining exhibition room can be seen by arrangement; the Institute for Materials Research directs prospective visitors to its permanent exhibition page to book. Other parts of the building are in daily use as offices and meeting rooms and are not open.
- Who was Honda Memorial Hall named after?
- Kōtarō Honda, founder of what became the Institute for Materials Research and sixth president of Tohoku Imperial University. He developed KS magnet steel in 1917. A committee marking his twenty-fifth year at the university funded the building, which was completed in 1941.
- What cultural property status does Honda Memorial Hall hold?
- It is a Registered Tangible Cultural Property (Buildings), registration number 04-0204, entered on the register on 14 October 2021 under the criterion for buildings contributing to the historical landscape of the country. Registration is a lighter protection tier than Important Cultural Property designation.
- What architectural features distinguish Honda Memorial Hall?
- The tile-clad exterior with emphasized pilasters and ranks of rectangular windows, the large canopy projecting over the entrance carriage porch, and the marble-lined entrance hall leading to a stairwell laid out on an elliptical plan. The 1994 renovation deliberately kept the original marble surfaces.
- How do you get to Honda Memorial Hall from Sendai Station?
- Katahira campus is roughly a twenty-minute walk west of Sendai Station, or a short ride on the Namboku subway line to Itsutsubashi followed by a walk. The building stands within the campus at 2-1-5 Katahira, Aoba Ward.
