Tokyo Printing City Cooperative

Wikipedia's article on Shiomi (Kōtō) says of the Tokyo Printing City Cooperative (協同組合東京プリンティングシティ): "Founded 1981. Tokyo's first printing industrial estate." (no source is cited). The 2008 Shiomi district town-planning policy states that "printing works are concentrated west of Shiomi Station".

In June 2004 the printing estate was rezoned from an exclusively industrial zone to a quasi-industrial zone, at the same time as a district plan was decided. The "Shiomi 2-chōme West district plan" (about 4.1 ha), decided on 24 June 2004, aims "to restrain housing and form a mixed district where diverse production and distribution functions, beginning with printing, can coexist with commercial and business functions".

The policy revised in 2026 likewise says that the mixed-use zone around the station should be developed "while respecting the existing printing industry, a characteristic of the district".
