A stone front gate without doors

Mori Clinic Gate (森医院門, Mori Iin Mon) is the stone front gate of the Mori medical family's estate in Manoshinmachi, Sado City, Niigata Prefecture, built in the early Showa era and registered as a Registered Tangible Cultural Property on 18 October 2006.

It stands on the northeast side of the plot, facing the street. The opening between the posts is 3.8 metres and the gate is 2.8 metres high. Square stone posts, 30 centimetres on a side, rise from a raised base, and the gate was never fitted with doors. Sado City lists it under the name omotemon, the front gate.

Registration and its place among the eight

The gate was registered for its contribution to the historic landscape. According to the Agency for Cultural Affairs, Mori Clinic Gate marks the entrance to a large plot and gives the estate a dignified street front, and that is the basis of its registration.

It is the only stone structure among the eight at Mori Clinic. The national database even counts it differently, as one structure rather than one building.

The missing doors matter. This is a gate that marks a boundary and presents a face to the street rather than one that shuts. That is presumably why the Agency for Cultural Affairs describes its role in terms of defining the entrance and setting out the front of the estate.

Three finishes on one post

The faces of the stone posts are dressed with a fine bush-hammered texture, known as kotataki, the edges are polished smooth, and the tops are shaped into hemispheres. The even, tooled surface makes the crisp polished arrises stand out, sharpening the outline of each post.

So each post carries three finishes at once: tooled faces, polished edges and a rounded cap. Sado City's summary likewise credits the gate's careful stonework with giving the estate its formal front. Looking at a post at an angle from the street is the easiest way to see the difference between face and edge.

Seeing Mori Clinic Gate

Because it faces the street, Mori Clinic Gate is the one structure you can see up close. It is still the entrance to a private home, though, and the ground inside the posts is private property even without doors. Do not walk through or step inside.

There is no official guidance on photography. If you stop on the street, keep clear of passing traffic. Getting there from Ryotsu Port is explained on the Mori Clinic page.
