Japanese architecture immersion - Toyama-tei (Toyama Memorial Museum)


A classic house nestled in rice fields, represents exclusive design, materials, and artisanal techniques of Japanese architecture

It was about 40 minutes by train from Ueno to Okegawa Station in the north of Tokyo. From Okegawa, I took a little travel by local bus heading for Kawajima, a town remaining rural landscape. After crossing the river, I got off the bus at a stop in the farm town and walked down a little while viewing nice rice fields around there. Then, I reached a large wooden gate, looks like it of Samurai load residence. Now, I am in front of the Toyama-tei.

Toyama-tei or Toyama Memorial Museum is a former residence originally constructed by Gen-ichi Toyama (1890-1972), the founder of Nikko Securities. The Toyama family used to be wealthy, but their business went down when Gen-ichi was a child. After going through a rough time, Gen-ichi acquired great success in his own business, then regained the place where he was born and built the house Toyama-tei for his mother, who also had hardship. The buildings on the premises consist of a former residential house with a Japanese garden and a museum building, all open for public as Toyama Memorial Museum.

The construction began in 1933, was finally completed after spending two years and seven months. The initial plan of the main building, 40 or 50 Tsubo (132 sq m to 165 sqm) in size, was revised again and again in the course of pursuing ideals, resulted in the expansion reached 400 Tsubo (1322 sq m) in the end. During the construction, over thirty-five thousand architectural experts were engaged, used only selective wooden materials sought to collect from all over Japan. Representing the high-end architectural technology at that time, Toyama-tei was designated in 2018 as an important cultural property of Japan.

Toyama Memorial Museum

Toyama-tei comprises three wooden buildings in different traditional Japanese housing styles, which can be described as the feature of the house. The house includes a central wing in Shoin style, west wing in Sukiya-zukuri, and east wing in style of Wealthy-farmer's-house, all of which naturally emphasize their uniqueness in comparison. Each wing is separated but linked with a long corridor, creates a flow so that the different wings can be harmonized naturally. Following the corridor, it allows visitors to look around the rooms and enjoy different atmospheres with a feeling of comfort.

Although all the rooms have been not lavishly decorated, the understated brilliance can be found in the serene interior. Along the way, you look around the rooms and enjoy the relaxing, tranquil atmosphere, have a careful look at the detailed works, such as wooden frames and latticeworks at doors. You will realize the amazing artisanal techniques applied to those creations here and there.

This traditional house has been well-planed in a fusion of classic and modern styles as well. The large window glasses, which were hardly produced in Japan, were imported from the USA. The garden was designed with consideration for the perfect view from the room through the windows. Sitting by the window, gazing at the garden in silence, is what attracts visitors.
