Hori Shoten

A Lock Merchant's Building in Shimbashi

The Hori Shoten Building (堀商店, commonly called the Hori Building or Hori Biru) stands on a corner site in Shimbashi, Minato Ward, Tokyo, was completed in 1932, and was entered on Japan's national register of Tangible Cultural Properties in 1998. It was built as the head office of Hori Shoten, a firm making locks and architectural metal fittings that had traded on the same corner since 1890.

The Agency for Cultural Affairs records the structure as reinforced concrete, four storeys with a rooftop tower, covering 173 square metres of ground. Later accounts from the companies now managing the building describe it as five storeys above ground with a basement, counting differently and including levels the 1998 ledger did not itemise. The plot is small and the building fills it, wrapping the junction where Sotobori-dori meets Akarenga-dori.

Its date matters. The Great Kanto Earthquake of 1923 flattened much of this quarter, and the reconstruction that followed replaced timber shopfronts with fireproof frames. Hori Shoten rebuilt in concrete nine years afterwards, part of a wave of small commercial buildings that gave central Tokyo a new grain: narrow, urban, four or five storeys, faced in tile.

The Design and Why It Was Registered

Registration took effect on 21 April 1998, with public notice on 9 June. The building carries registration number 13-0009 and belongs to the ninth round of registrations, making it one of the earliest entries from Tokyo. The criterion applied was that the building serves as a model of design, the stricter of the criteria available under the registration system.

The Agency's own description is specific about what earned it. Scratch tile on the outer walls, a face of vertical grooves that catches raking light. Window surrounds banded to stress the horizontal. At the western end, a stair tower whose windows run the other way, vertically, breaking the horizontal reading. And an eaves treatment the ledger calls unusual, a run of ornament under the parapet that does not follow any standard pattern book.

The result sits between two idioms. The window banding and the plain massing belong to the modernism arriving in Japan around 1930. The cornice ornament, the entrance surround, the metalwork inside belong to an older decorative habit. For a company that sold door handles, hinges and locks, the fittings were also a showroom.

Attribution rests on secondary sources rather than the Agency ledger, which records no architect. Published accounts credit a joint design by Kubo Toshio and his elder brother Kobayashi Masatsugu, with Ando-gumi as contractor. Kobayashi worked in the building sections of the Ministry of Finance and the Ministry of Home Affairs and had a hand in the National Diet Building and the Meiji Memorial Picture Gallery. The younger brother's given name appears as both Toshio written 敏雄 and 敏夫 depending on the source, and little else of his work is documented. Recognition came in two steps: selection as a Tokyo Metropolitan Historic Building in 1989, then national registration in 1998.

Visiting

This is the rare registered property you can walk into and sit down in. After Hori Shoten moved its operations out, the owner signed a master lease with Takenaka Corporation in 2020; the building was repaired and reopened on 1 April 2021 as GOOD OFFICE Shimbashi, a shared workspace of roughly twenty rooms across six levels, with a lounge, a kitchen-equipped meeting room and a roof terrace. In July 2025 a café called goodcoffee Shimbashi by goodroom opened on the ground floor, which means the interior is now accessible to anyone buying a coffee.

Upper floors are members' space and not open to casual visitors. The building has appeared in the Tokyo Architecture Festival programme, during which the ground-floor lounge has been opened and limited-capacity tours of the upper levels run by the conservation team have been offered; anyone hoping to see more should check that festival's schedule.

Getting there is easy. The address is 2-5-2 Shimbashi, Minato Ward, about one minute on foot from Shimbashi Station on the Tokyo Metro Ginza line and three minutes from the Karasumori exit of JR Shimbashi Station. The exterior can be photographed from the pavement; the corner reads best from the far side of the crossing, where the stair tower and the rooftop element line up. Ground-floor windows once displayed the company's locks and handles, though that display has since been removed.
