The Office That Ran a Cotton Company
The Former Nakashichi Cotton Main Store Main House (Former Office) is a two-storey timber building at 28-1 Okada Kaito in Chita, Aichi Prefecture, built in 1914 (Taisho 3) and added to the national register of Registered Tangible Cultural Properties on 28 June 2017 (Heisei 29). It stands on the western shore of the northern Chita Peninsula, in a district that supplied cotton cloth to Japan for roughly three centuries.
The company behind it began much earlier. Nakajima Shichiemon, a cotton wholesaler in Okada village, held a licence to trade in cloth from the middle of the Edo period, and the family business closed in the Meiji era. In 1896 (Meiji 29), associates who did not want the trade to disappear founded Nakashichi Momen, a partnership company, and installed twenty-four powered looms, the first mechanised weaving in Okada. The building that survives today was the firm's head office.
Its later history is unusual for a building of this kind. The Agency for Cultural Affairs records the structure as built in 1914 and relocated in 1945 (Showa 20). Buildings in Japan were often moved intact by Hikiya rather than demolished, and the office now sits on a different alignment from the one it originally occupied. Nothing about the exterior announces this. The move is legible only in the way the entrance meets the lane.
The plan is straightforward and reveals what the building was for. A doorway opens at the centre, set slightly toward the east. The office proper occupied the western half of the ground floor, where accounts were kept and orders taken. Two rooms on the upper floor were reserved for receiving visitors, which in a wholesale business meant buyers, brokers and mill agents.
Why This Building Was Registered
Japan runs two separate systems for architectural heritage. The older one applies designation to a small number of exceptional buildings and carries strict controls on any change to them. The registration system, created in 1996, casts a wider net over buildings from the nineteenth and twentieth centuries that shape the character of a place. The Former Nakashichi Cotton Main Store Main House (Former Office) belongs to the second system, and the registration record names a specific reason: the building is a model of its type.
That criterion matters. Five other structures on the same site were registered on the same day under a different heading, for contributing to the historic landscape. Only the main house was cited for the quality of its design. Among more than a dozen registered buildings in the Okada district, it is the one the assessors singled out as exemplary rather than merely characteristic.
What earns that reading is the treatment of the exterior. The walls are finished in black plaster, a costly and demanding surface that had to be applied in many thin coats and burnished. Merchant buildings across central Japan used white plaster far more often. Black cost more and signalled more. On a commercial head office in a village of weavers, it made a statement about standing that the ledgers inside would have confirmed.
The building also documents a transition that is otherwise hard to see. Nakashichi Momen was a partnership company running powered looms, but its head office was built as a merchant house, not a factory office. Traditional carpentry served a modern corporate function. The Former Nakashichi Cotton Main Store Main House (Former Office) sits exactly on that seam.
What to Look At
Start with the roof. It is Irimoya-zukuri, hipped-and-gabled, covered in Sangawara-buki pantiles, and the slope carries a slight upward curve rather than running dead straight. Carpenters called this mukuri, and it takes more work than a flat pitch. Seen from the lane on a bright afternoon, the curve catches light along the tile courses and softens what would otherwise be a heavy mass.
Then look at the ridge ends. The Onigawara carry the company's trade mark, a mountain symbol combined with the numeral seven, moulded into the clay. Japanese merchant houses often marked their roofs this way, and the mark on these tiles is the closest thing the site has to a signature. The same emblem appears on the wall that runs along the eastern edge of the grounds.
The black plaster repays close attention. Stand near enough to see the surface at an angle and the finish reads as slightly uneven, the record of hand application rather than a sprayed coat. Where the plaster meets the timber openings, the joint is tight and deliberate.
The building is compact. Its floor area is 61 square metres, smaller than the workshop and dormitory behind it and smaller than either of the two storehouses at the western end of the site. A head office did not need to be large. It needed to be correct, and to be the first thing a visitor saw.
Visiting
The Former Nakashichi Cotton Main Store Main House (Former Office) is private property and the interior is not open to the public. The exterior can be seen from the public lane at any time, and photography from the street is not restricted. Please do not enter the grounds or look into windows.
Part of the site operates as Chita Momen Antenna Shop 478, a shop selling cloth and goods made from locally woven Chita cotton. It opens 10:00 to 16:00 and closes on Mondays, Tuesdays and Wednesdays; the telephone number is 0562-55-3239. Visiting the shop is the only way most people will get inside any part of the compound, so it is worth timing a visit for Thursday through Sunday.
By train, take the Meitetsu Tokoname Line to Asakura Station, then a Chita Bus service to the Daimon-mae stop. The building is about one minute on foot from there. By car, the site is roughly five minutes from the Nagaura interchange on the Nishi-Chita Sangyo Road, and a visitors' car park serves the Okada district.
The lane outside is narrow and residential, and the surrounding streets hold black board fences, plastered storehouses and a working post office building from 1902. Allow an hour if you intend to walk the district rather than stop at a single address. Opening hours and shop days were confirmed on 31 August 2026 and are worth rechecking before a long journey.

Q&A
- Can you go inside the Former Nakashichi Cotton Main Store Main House (Former Office)?
- No. The building is privately owned and the interior is closed to visitors. The exterior is visible from the public lane, and street-level photography is fine.
- When was the Former Nakashichi Cotton Main Store Main House registered, and under what category?
- It was entered on the national register on 28 June 2017 as a Registered Tangible Cultural Property in the buildings category, under registration number 23-0495. Registration is a lighter form of protection than designation as an Important Cultural Property.
- How do I get to the Former Nakashichi Cotton Main Store Main House from Nagoya?
- Take the Meitetsu Tokoname Line from Meitetsu Nagoya to Asakura Station, transfer to a Chita Bus service and get off at Daimon-mae. The walk from the bus stop takes about one minute.
- Why are the walls of the Former Nakashichi Cotton Main Store Main House black?
- The finish is black lime plaster, applied in thin coats and polished. It cost considerably more than the white plaster used on most merchant buildings, and a cotton company's head office used it to signal commercial standing.
- Is there anything else registered at the same address as the main house?
- Yes. Five further structures on the same grounds were registered on 28 June 2017: the nagayamon gate, the wall, the workshop and dormitory, and the south and north storehouses. Each has its own registration number.
