Former Yamadera Tsuneyama Family Residence Front Gate

The Longest Gate Left in a Castle Town

The Front Gate of the Former Yamadera Jozan Residence (旧山寺常山家住宅表門, Kyu-Yamadera Jōzan-ke Jūtaku Omotemon) is a late Edo-period gatehouse in the Matsushiro district of Nagano City, Nagano Prefecture, listed as a national Registered Tangible Cultural Property (Structure) on 25 April 2014 under registration number 20-0436.

It runs 23 metres along the eastern edge of the property, a single-storey timber structure with a tiled roof and a floor area of 109 square metres. The doorway at its centre is only 2.1 metres wide. To either side sit projecting lattice windows and yoriki-mado, the heavy vertical-barred windows used in warrior housing, with horizontal boarding protecting the lower wall. Among the surviving gates of the Matsushiro castle town, this one is the largest. Some local guides give the width as roughly 22 metres; the Agency for Cultural Affairs database records 23 metres, and that figure is used here.

The form is called a nagayamon, a gate with living quarters built into the wings on either side of the passage. In a samurai household those rooms housed attendants and storage. The Yamadera family served the Matsushiro domain at a middle rank with a stipend of 160 koku. Their best-known member, Yamadera Jozan (1807 to 1878), held the posts of commissioner of temples and shrines and district magistrate, and was grouped with Sakuma Shozan and Kambara Tozan as one of the Matsushiro sanzan, the town's three scholar-officials.

Why It Was Registered

Registration was granted under the criterion covering structures that contribute to the historic landscape of the country. The reasoning was less about the gate as an isolated object than about what it does to the street. Matsushiro retains a number of samurai gates, but none holds a frontage of this length, and the wall establishes the scale of the lane in front of it.

The window types repay a close look. A yoriki-mado lets someone inside watch the road while keeping the interior dim and hard to read from outside. A degoshi, the projecting lattice window, pushes forward from the wall plane and catches light along its bars. Both had a security function and both announced rank to anyone passing. The boarding at the base of the wall, called shitamiita, is plainer in purpose: it takes the rain and splash that would otherwise rot the plaster.

The main house of the estate was lost during the Taisho era, and its original extent is no longer known. What survives is this gate, a Taisho-period drawing-room building, a small memorial gate of 1940, and a pond garden fed from the Kanda River. Nagano City carried out repairs to the buildings and grounds in 2004 and now runs the site as a public facility. The garden carries its own listing as a Registered Monument in the scenic-site category.

What to Look For on a Visit

Step back across the lane before going in. Twenty-three metres of wall will not fit comfortably in one glance, and the ridge line running level above it gives the building its weight. Then look at the doorway again: 2.1 metres, modest against all that frontage. The gap between the two measurements explains the nagayamon better than any description.

Water runs in a channel at the foot of the wall. Matsushiro drew water from the Kanda River into a network of household ponds known as sensui, each garden passing its water downstream to the next. The Yamadera property is understood to sit at the head of one of those chains, so the sound of moving water belongs to the gate as much as the timber does.

Admission is free. The site opens at 9 a.m. and closes at 5 p.m., or 4:30 p.m. between November and March, with last entry half an hour before closing, and it shuts for the New Year period of 29 December through 3 January. There is no dedicated car park; visitors use the Zozan-higashi or municipal lots nearby. Buses run from the Zenkoji exit of JR Nagano Station and take about 30 minutes to the Matsushiro Hachijuni Ginko-mae stop, followed by a 15-minute walk. The Sanada Treasure Museum is a similar walk away, and Matsushiro Castle and Zozan Shrine sit within the same circuit.

Photography for personal use is unrestricted. Commercial shoots require permission from both the Nagano City Board of Education and the neighbourhood association that manages the site, so film and photo crews should apply in advance.
