A Villa That Outlived the Earthquake

On a plateau in the Kuwagayatsu valley of Hase, roughly forty meters above the shoreline, a long single-story house has looked out over Yuigahama beach for more than a century. It was finished in 1918 as a private retreat for Yamamoto Jotaro, a Mitsui man who later won a seat in the House of Representatives and went on to head the South Manchuria Railway. The building is now called Reigenkaku, and since 1981 it has belonged to the religious organization Shinreikyo, which took it on with a promise: to keep it as it was rather than turn it into a restaurant or an inn.

That promise matters more than it might sound. Five years after the house went up, the Great Kanto Earthquake of 1923 leveled much of the region. Very few Kamakura residences from before that day are still standing, and fewer still keep their gardens and their outlook. Reigenkaku is one of them.

Sukiya Rooms, Built by Kyoto Hands

The house is a work of sukiya architecture, the refined residential style that grew out of the tea room and prizes restraint over display. Rooms unfold from a guest parlor at the southern end, running north along two wings. To the west lie the living quarters and kitchen; to the east, a Western-style room and a tea room. The living room juts out over the edge of the cliff, while the formal entrance sits at the base of the slope below, the two levels joined by an interior stair.

Local accounts hold that the timber and finishing materials were brought from Kyoto and worked by Kyoto carpenters. The details reward a slow look: the slender beam over the entrance, the fine lattice of the windows, the gently convex mukuri curve of the roof, and ceilings deliberately kept low in the corridors so that the main hall feels wider by contrast. The tea room and the house together are said to carry the name Muian, given by Yamamoto's tea master, the Mitsui figure and collector Masuda Takashi.

Why It Is Registered

Reigenkaku is a Registered Tangible Cultural Property, a national category that recognizes buildings of value and encourages their preservation while leaving them in everyday use. It was entered on the register on November 29, 2016, together with three companion structures on the same grounds: a waiting arbor, a plaster-and-tile wall, and a gate.

Among the four, the main house alone was listed under the criterion reserved for works that serve as a model of design. Assessors singled out a scheme that echoes the Zangetsu-tei, the celebrated tea room of the Omotesenke school, and praised the whole as a polished example of modern sukiya building. The 1918 structure gained a further extension in 1956, when a tea room was added at the northeast end during the years the property passed to Kuki Kenichiro.

What Draws the Eye

The setting is half the pleasure. From the garden beside the main hall the ground falls away toward the water, and on a clear day the sweep of Yuigahama opens below. The grounds run to about 5,000 tsubo, roughly 1.6 hectares, planted over the decades with a wide range of trees and shrubs.

Inside, the building rewards visitors who notice how space is managed rather than filled. A low corridor ceiling gives way to a broad room; a plain post frames a view of the garden; the mukuri roofline reads differently from each angle of approach. This is a house built for people who understood tea, and its restraint is the point.

Q&A

QCan I visit Reigenkaku?
AIt is an active facility of the Shinreikyo organization and is not generally open to the public. Group viewings are held only a few times a year, and casual drop-in visits are not possible. Check with the organization before planning any visit.
QWho was Yamamoto Jotaro?
AHe was a businessman who rose through the Mitsui trading house, later became a member of the House of Representatives, and served as president of the South Manchuria Railway. He built this house as his Kamakura villa, completed in 1918.
QWhat is a Registered Tangible Cultural Property?
AIt is a lighter national category than a Designated Important Cultural Property, introduced to protect a wider range of buildings, especially those from the modern era, while keeping them in ordinary use. Reigenkaku was registered in 2016.
QWhat is sukiya architecture?
AIt is a residential style shaped by the aesthetics of the tea room, favoring natural materials, understatement, and asymmetry over formal grandeur. Reigenkaku is regarded as a high-quality modern example.
QWhat else is nearby that I can actually enter?
AThe house sits in Hase, minutes from Hasedera temple and the Great Buddha at Kotoku-in. The Kamakura Museum of Literature, itself a former villa, is another accessible stop with a garden and sea view.
