What the Akada Family Residence Detached Room Is

The Akada Family Residence Detached Room (赤田家住宅離れ座敷, Akada-ke Jūtaku Hanare-zashiki) is a two-storey timber guest pavilion built in 1916 in Otamachi, Nagahama City, Shiga Prefecture, and entered as a Registered Tangible Cultural Property on 6 August 2025. It covers 59 square metres under a tiled roof and stands southeast of the main house, facing west.

The roof is a simple gable, entered from the long side in the Hirairi manner and laid with Sangawara-buki tiles. A lean-to roof, or Geya, wraps around the building at a lower level, so that the two-storey block seems to settle into the ground and looks lower than it is.

It was built six years after the main house of 1910. A hanare-zashiki is a separate pavilion where a household could receive guests or its head could retreat, apart from the bustle of the main house, and the plan of this one is arranged for exactly that.

Why It Was Listed

Like the main house, the Akada Family Residence Detached Room was listed as a model of design. The Agency for Cultural Affairs singles out the care taken over its materials and calls it a reception room of high quality.

You step up from a small entry floor of beaten earth in the northwest corner and move east into a suite of connected reception rooms, which can be opened into a single hall by sliding back the partitions between them. In the southwest corner sits a study of just three tatami mats, and the west wall is pierced by a round window. A modest building thus holds both a room for company and a room for solitude.

The alcove post, or Tokobashira, is red pine with its bark left on, a device that brings the look of a freshly felled tree into the room and was favoured in the relaxed, tea-influenced sukiya style. The frame at the front of the alcove is black persimmon, kurogaki, the rare heartwood of the persimmon tree that develops black streaks and figures and has long been prized as a luxury timber. Red bark and black-streaked wood: two strongly contrasting materials meet at a single alcove.

What to Look For

The interest of the Akada Family Residence Detached Room lies more in its materials than in its outline. Because the pine post keeps its bark, its curves and texture are unique to that one tree. Below it the dark persimmon frame runs dead level, so the natural vertical of the post meets a polished horizontal in the same small space.

The round window on the west side is the other signature. In architecture built from rectangles, a circular opening catches the eye at once, and since the west side is the front of the pavilion, the window is part of the face it presents.

The three-mat study deserves a thought too. Building a private study into a guest pavilion shows that the room was meant for reading and writing as well as for hospitality, a telling detail in a rural household of 1916.

Visiting

The Akada Family Residence Detached Room is part of a private home and is not open. Neither the Agency for Cultural Affairs nor Nagahama City lists any chance to see the bark-covered alcove post, the persimmon frame or the study (checked 27 September 2026).

The pavilion stands inside the compound, southeast of the main house, and cannot really be seen from the road. The Agency's online database publishes an exterior photograph of the west front, which is the best way to get a sense of it. Stay outside the gate and photograph only from the public road.
