Baba Family Residence Nagayamon Gate

A Gate Still Doing Its Job

Baba-ke Jūtaku Nagayamon (馬場家住宅長屋門, also written Babake Jutaku Nagayamon, "the Baba Family Residence Row-House Gate") is a late Edo-period gatehouse at Matsushiro 1513 in the Matsushiro district of Nagano City, Nagano Prefecture, entered on Japan's national register of Tangible Cultural Properties on 26 December 2005. The Agency for Cultural Affairs dates its construction to the later Edo period, somewhere in the span of 1751 to 1829.

The building presents its long side to the street, facing west. Its frontage runs seven and a half ken (about 13.6 metres) and its depth two ken (about 3.6 metres), a single storey under thatch. The thatch is currently protected by sheet metal laid over it as a temporary covering, which is how the national record describes the roof.

A nagayamon is not quite a gate in the freestanding sense. The passage is cut through the middle of a low, elongated building, so that walking under it means passing through a house. In the samurai quarters of a castle town the rooms flanking the passage held retainers, servants, tools, or firewood. Here the record notes two rooms on the north side of the opening and an earthen-floored storeroom on the south. The main doors swing outward in a pair, and beside them sits a kuguri-do, a low wicket door for one person at a time, used when the big leaves stayed shut.

Walls are built in the shinkabe manner, with the structural posts left visible against white lime plaster. The lower band is boarded in oshibuchi shitami itabari, overlapping horizontal planks pinned by slender vertical battens. Nagano City's own description of the building differs slightly from the national record, calling the rooms on both sides of the passage retainers' quarters and counting four courses in the boarded skirt. Where the two accounts diverge, the Agency for Cultural Affairs record takes precedence.

Registered, Not Designated: What the Category Means

Japan protects historic buildings in tiers, and the distinction matters for anyone reading a plaque. A National Treasure (kokuhō) sits at the top, followed by Important Cultural Property (jūyō bunkazai). Both are designations, applied selectively and carrying heavy obligations on the owner. A Registered Tangible Cultural Property (tōroku yūkei bunkazai) belongs to a separate and lighter system introduced in 1996, aimed at buildings generally more than fifty years old that shape the character of their surroundings. Registration asks for notification before major alteration rather than approval for every repair, on the reasoning that a building kept in use survives better than one frozen.

Baba-ke Jūtaku Nagayamon holds registration number 20-0228, granted in the forty-eighth round of registrations, with the public notice issued on 27 December 2005, one day after the register entry. The criterion applied was the first of the three available: that the building contributes to the historic character of the national landscape. That criterion fits the case precisely. The gate matters less for any single carved detail than for what it does to the street.

The national record calls it a large gate for a samurai quarter, and the comparison worth making is close at hand. Along the same walking route, the front gate of the Yamadera Jōzan residence measures roughly 22 metres across and ranks as the largest surviving gate in the Matsushiro castle town. Baba-ke Jūtaku Nagayamon is smaller, but it belongs to the same family of structures and reads as substantial rather than modest. The recorded building area is 37 square metres.

Matsushiro was the seat of the Sanada family, who held the domain at a nominal 100,000 koku from 1622 until the abolition of the domains. The samurai houses that line these streets were not monuments. They were addresses. What survives of them survives unevenly, and gates have outlasted the houses behind them more often than the reverse, because a gate faces the street and a street is slower to change than a garden.

Seeing It on Foot

The gate stands on what Nagano City calls the rekishiteki michisuji, the historic route running from the former Bunbu Gakkō, the domain school opened in 1855, past Zōzan Shrine and on to the Yamadera Jōzan residence. This is a walking course of perhaps twenty minutes end to end, and Baba-ke Jūtaku Nagayamon sits along it rather than at any of its destinations. Most people meet the building without meaning to.

Stop at the far side of the road and look at the roofline. The metal sheeting reads as flat and grey where thatch would read as deep and textured, and the eaves still carry the thickness of the original construction underneath. The proportion is the thing to notice: a very long, very low mass, with the plastered upper wall floating above a dark boarded base, broken only once by the opening of the passage.

Then look at the wicket door. Its threshold is raised and its head is low, which forced anyone using it to duck and step high at the same moment. That awkwardness was the point. A visitor entering through a kuguri-do could not rush and could not carry a drawn weapon comfortably.

This is private property. There is no ticket office, no opening hours, and no interior access. The building is looked at from the public road and nothing more, and visitors should keep to the roadway and avoid the entrance itself. Photographing the exterior from the street is unproblematic, though pointing a lens through the passage into the grounds beyond is not.

Getting to Matsushiro takes a bus. The Nagano Electric Railway line that once served the town closed at the end of March 2012, so the practical approach is the Alpico Kōtsū number 30 Matsushiro service from Nagano Station, roughly 30 to 40 minutes, about 660 yen one way, alighting at Matsushiro Hachijūni Ginkō Mae. By car it is about ten minutes from the Nagano interchange on the Jōshin-etsu Expressway, and public parking is available at Daikanchō. Reaching Nagano itself is straightforward on the Hokuriku Shinkansen.
