The history of Toa Corporation stretches back to 1908, when Soichiro Asano, founder of the Asano industrial conglomerate, submitted a bold plan to the Kanagawa prefectural government to reclaim nearly five million square metres of land at the mouth of the Tsurumi River.

With the support of Eiichi Shibusawa and Zenjiro Yasuda, Asano set up the Tsurumi Umetate Kumiai (Tsurumi Reclamation Association) in 1912 as the first step in his grand vision to reclaim part of Tokyo Bay.

Reclamation work begins and a new industrial precinct emerges

Tsurumi Marine Works was founded in 1914 to take over the project from the Tsurumi Reclamation Association. By the end of 1915, the new company had completed work on the No. 7 section (now Suehiro-cho in Tsurumi-ku, Kanagawa Prefecture) with an area of 230,000 m2, of which just over 80,000 m2 was sold to Asahi Glass. The Asahi Glass factory at Tsurumi was the very first facility to be built on reclaimed land at Tsurumi-Kawasaki.

Tokyo Bay Marine Works was founded in January 1920 and acquired Tsurumi Marine Works taking over all its projects with a broader vision of extending the reclamation area from Tsurumi into Tokyo Bay.

Although the Great Kanto Earthquake on 1 September, 1923 caused extensive damage in Tokyo and elsewhere, the reclaimed land in Tsurumi-Kawasaki was left relatively unharmed. This outcome served to demonstrate the safety of the reclaimed land and prompted many factories to relocate from Tokyo to the Keihin zone, which began to flourish as a result.

The combination of the financial shock sparked by the collapse of Watanabe Bank on 15 March, 1927 and the downturn that followed the lifting of the gold embargo in January 1930 catapulted the domestic economy into a major crisis. Tokyo Bay Marine Works found itself in a parlous financial state as sales of reclaimed land fell away sharply due to industry’s unwillingness to consider new plant and equipment investments.

A new dawn for Tokyo Bay Marine Works

Signs of a recovery in the Company’s fortunes began to emerge as the rayon boom in 1933 generated a surge in demand for more reclaimed land for new factories and associated industrial sites along the coast of the Seto Inland Sea. The Company was also engaged by Ford Japan to provide a site area of around 370,000 m2 in the northern half of Suehiro-cho, Tsurumi-ku.

Up until 1937, Kowan Kogyo had been developing land for peacetime industries in small to medium-scale ports and harbours. However, the company soon found itself called upon for large-scale land development projects for the military and related wartime industries, including some overseas projects. On 30 April, 1944, Tokyo Bay Marine Works and Kowan Kogyo merged to form a new entity called Toa Kowan Kogyo.
