## Company history

Haseko was founded by Takehiko Hasegawa in February 1937 as Hasegawa Komuten, a private construction business in Amagasaki, Hyogo, and was incorporated in August 1946. It completed its first condominium, Ashiya Matsuhama Heights, in 1969. From 1973, the company developed its CONBUS standardized production system; that year it reported reaching Japan’s leading position in cumulative condominium construction, with 35,000 units. [12](https://www.haseko.co.jp/hc/english/company/history.html) [4](https://www.haseko.co.jp/hc/english/company/library/history.html)

Haseko completed its first overseas condominium, 444 Nahua in Hawaii, in 1974, and changed its corporate name to HASEKO Corporation in 1988. Later housing milestones included Acrocity Towers in 1992, Hills Kugahara in 1999, and House Solana, its first skeleton-infill housing project, in 2000. In 2015, Sohgoh Real Estate and JOINT CORPORATION became subsidiaries, marking further expansion through acquisitions.
