Dōjunkai

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.

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.

From 1926 to 1930, Dōjunkai created fifteen apartment complexes (apāto or apātomento), two in Yokohama and the rest in Tokyo.

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.

After the war, the government sold the land of most of the complexes to real estate companies, notably Mori Building.
