The Building That Went Up First

Min'unkaku Ochiairo Entrance Building (眠雲閣落合樓玄関棟) is a single-storey timber building of 1933 at the hot spring inn Ochiairo in Yugashima, Izu City, Shizuoka Prefecture, entered on the national register of Registered Tangible Cultural Properties on 18 November 1999. It carries an Irimoya-zukuri hipped-and-gabled roof laid with Sangawara-buki pantiles, and its floor area is 80 square metres.

Of the seven registered buildings on this site, Min'unkaku Ochiairo Entrance Building came first. When it was finished, the main building, Min'untei and the rosewood banquet hall did not yet exist. The owners settled the question of how arriving guests would be received before they built anything else. Pass through the entrance and a corridor runs east to the residence building, which was the innkeeper's own house.

Why It Is Registered

The criterion cited for Min'unkaku Ochiairo Entrance Building is that the building serves as a model of design. The Agency for Cultural Affairs database singles out the carved transoms as giving the building its dignity. What earned the listing is not size but the handling of a threshold.

The point shows in the roof. This is a one-storey building, yet it carries a full hipped-and-gabled roof of the kind normally reserved for something taller. A second floor would have bought more room but flattened the profile seen from the forecourt. Against a modest 80 square metres of floor, the roof is generous, and a guest stepping out of a car looks up at the eaves without being told to. Japanese hot spring inns of the early Shōwa era thought hard about this moment, and Min'unkaku Ochiairo Entrance Building preserves that thinking in built form.

Its register number is 22-0057, the lowest of the five buildings here listed on the same day in 1999.

What to Look At

Start with the Ranma, the transom panels set above the lintels. Those in Min'unkaku Ochiairo Entrance Building are pierced carvings held within their frames, and they sit at about the height a guest looks up while shedding a coat. The whole encounter lasts perhaps thirty seconds unless you deliberately stop.

Step outside and follow the roof. You can watch the run of pantiles break at the hip, and because the eaves of a single-storey building are low, the curve of each individual tile stays within reach of the naked eye. Neither the two-storey main building nor the banquet hall offers that distance.

The corridor leading east belongs to the reading of Min'unkaku Ochiairo Entrance Building as well. Built around 1935 and registered together with the residence building, it is the point at which the path of an arriving guest and the path of the innkeeper going home part company.

Visiting

Min'unkaku Ochiairo Entrance Building is the working front door of an operating inn and is not open to the general public. Only overnight guests go inside. That said, its function guarantees the encounter: anyone who stays passes through it on arrival and again on departure, which makes it the most reliably seen of the seven buildings.

For the exterior, stand square on at the forecourt, where the ridge line and the transom-bearing facade come into one view. Inn staff run a walking commentary on the registered buildings for guests, and Min'unkaku Ochiairo Entrance Building is where it begins.

The inn publishes no statement on photography. Since this is where other guests are arriving and leaving, pick a quiet moment. Directions to the site and the conditions for staying are set out on the Min'unkaku Ochiairo page.
