The Front Building of Komatsuya
The Komatsuya Ryokan Main Building (小松屋旅館本館, Komatsuya Ryokan Honkan) is a two-storey timber inn building of 1951 at Iwamuro Onsen in Nishikan Ward, Niigata City, Niigata Prefecture, and it was registered as a Registered Tangible Cultural Property on 1 August 2016 under registration number 15-0436.
It stands a little back from the old Hokkoku Kaido highway and faces east, with a hip-and-gable, Irimoya-zukuri, entrance porch projecting from the front. The tiled main roof is hip-and-gable at its east end and a plain gable, Kirizuma-zukuri, at its west end. The building area is 154 square meters, and three guest rooms line the upper floor. It was renovated in 1970 and again in 1978.
Why It Was Registered: The Postwar Face of the Inn
The Komatsuya Ryokan Main Building was registered for contributing to the historic landscape. The Agency for Cultural Affairs introduces it as a long-established inn of Iwamuro Onsen, a spa town that prospered by lodging pilgrims to Yahiko Shrine, and records the particulars of its front: set back from the road, with its entrance thrust forward to meet arriving guests. That frontage is part of what gives the spa town its character.
The Main Building is younger than two of the inn's other registered buildings, the Hall Wing of 1914 and the Front Zashiki Wing of 1925. Built in 1951, in the early postwar years, it took over the role of receiving guests. Today it sits at the center of the group: the Hall Wing attaches at its southeast corner and the Inner Zashiki Wing joins it on the west by a covered corridor.
The national description also notes that the woodwork is elaborate, with prized timber used at key points. The building was finished with care inside as well as out.
What to Look For: A Two-Faced Roof and a Projecting Porch
Approach the Komatsuya Ryokan Main Building from the front and the first thing you see is the entrance porch, pushed forward under its own small hip-and-gable roof, with the two-storey body of the building behind it. Everything about the front draws the eye to that porch.
The main roof changes shape from one end to the other. The east end, the entrance side, is hip-and-gable; the west end is a simple gable. It reads as a decision to give the public face the more formal profile and keep the back plain. If you can see the building from the side, compare the two ends of the ridge.
Inside, the three upstairs guest rooms are the part singled out for their joinery. The national description does not say exactly where the prized timber is used, so if you stay, look closely at the Tokobashira and the crosspiece over the Tokonoma alcove, where such wood usually goes.
Seeing the Komatsuya Ryokan Main Building
Because the Komatsuya Ryokan Main Building faces east, you can see the projecting porch and the east end of the roof from in front of the inn. It is a working inn, so unless you are a guest or have booked a meal, do not go beyond the entrance, and look from a spot where you are not in the way of guests coming and going.
The interior is open to overnight guests and diners with a booking. The inn's room list places a room called Tenjin on the upper floor at the top of the stairs just inside the entrance. As the entrance is in the Main Building, Tenjin is probably one of its upstairs rooms, though the inn does not name the building. If you want to stay in the Main Building, confirm when booking, and ask about photography at the same time.
