Dōjunkai

Japanese construction company

Dōjunkai (shinjitai: 同潤会, kyūjitai: 同潤會) was a corporation set up a year after the 1923 Kantō earthquake to provide reinforced concrete (and thus earthquake- and fire-resistant) collective housing in the Tokyo area. Its formal name was Zaidan-hōjin Dōjunkai (財団法人同潤会), i.e. the Dōjunkai corporation. The suffix kai means organization, and dōjun was a term coined to suggest the spread of the nutritious benefit of the water of river and sea.2 It ceased to exist in 1941.1 Wikipedia text CC BY-SA 4.0

Dōjunkai (shinjitai: 同潤会, kyūjitai: 同潤會) was a corporation set up a year after the 1923 Kantō earthquake to provide reinforced concrete (and thus earthquake- and fire-resistant) collective housing in the Tokyo area. Its formal name was Zaidan-hōjin Dōjunkai (財団法人同潤会), i.e. the Dōjunkai corporation. The suffix kai means organization, and dōjun was a term coined to suggest the spread of the nutritious benefit of the water of river and sea. It was overseen by the Home Ministry.2

The story

From 1926 to 1930, Dōjunkai created fifteen apartment complexes (apāto or apātomento), two in Yokohama and the rest in Tokyo. Among the latter, the best known is Dōjunkai Aoyama Apartments (built 1926–27), which stood on the avenue of Omotesandō toward its Harajuku Station end. Toward the end of what was by Tokyo standards a long life, the ivy-covered building was increasingly used for ateliers and small independent shops. It was demolished for the 2005 construction by Mori Building of Omotesando Hills, a conventional shopping mall. Dōjunkai built one last complex in Tokyo, Dōjunkai Edogawa apāto, between 1932 and 1934.

Dōjunkai was wound up in 1941.

Remarkably, all the apartment complexes survived wartime bombing.

After the war, the government sold the land of most of the complexes to real estate companies, notably Mori Building. Thereafter, the combination of desire for greater profits, lack of advance publicity, and lack of government interest in this genre of architecture, in addition to inadequate maintenance and the lack of amenities (notably individual bathing facilities) now taken for granted, have led to the destruction of most of the complexes in the name of "site development".

Currently the only original building can be seen at a conversion project at Dojunkan building, Omotesando Hills. Some shops and galleries are in the building with its facade of a genuine three-stories apartment.
