Overview
TOYO Industry Co., Ltd. is a Japanese engineering and trading company headquartered in Minato-ku, Tokyo. Founded in December 1965 as a trading house for industrial measuring instruments and control equipment, the company has evolved into a specialist supplier of equipment, devices, and systems for shield tunneling (shield工法) — the method used to excavate major urban tunnels for subways, water and sewage mains, underground roads, and utility corridors. Its core offerings include slurry shield, earth-pressure shield, and hybrid shield equipment; fluid transport systems; comprehensive shield management systems; and related civil engineering materials and industrial products. The company also rents and sells AEDs (automated external defibrillators). TOYO Industry began its involvement in shield tunneling around 1970, becoming one of the first Japanese firms to enter the field. It has since supplied equipment to numerous landmark projects, including the Tokyo Bay Aqua-Line, the Eurotunnel, the Singapore Circle Line, and Seoul Metro. The company operates a head office in Tokyo, an Osaka sales office, and a Chiba factory. In 2008, it became a consolidated subsidiary of Kanamoto Co., Ltd., a major construction equipment rental company listed on the Tokyo Stock Exchange. As of its company profile, TOYO Industry has 27 employees and capital of 31.2 million yen. Its president is Tetsuo Kanamoto. The company positions itself under the management philosophy of 'technology-based management' (技術立社), aiming to contribute to social infrastructure through continuous development of new technologies and better systems.
History
TOYO Industry Co., Ltd. was established on December 9, 1965, with capital of 1 million yen, headquartered in Ota-ku, Tokyo. It began as a trading company for industrial measuring instruments and control equipment. In March 1970, the company made its first delivery of fluid transport equipment for slurry shield tunneling to the Keiyo Line Haneda Tunnel construction project, marking its entry into the shield tunneling field. Around this time, it became one of the first Japanese companies to enter the shield tunneling sector, leveraging its accumulated control technology. In October 1970, the head office was relocated to Kanda-Sakumacho, Chiyoda-ku, Tokyo, and in December 1970, capital was increased to 1.5 million yen. Throughout the 1970s and 1980s, TOYO Industry developed and delivered various shield-related systems and equipment. In May 1975, it developed its first excavation management system. Capital was increased to 3 million yen in February 1976 and to 12 million yen in March 1976. In March 1978, it developed a simultaneous automatic backfill injection system. Capital was increased to 20.8 million yen in February 1981. In December 1981, the Chiba Factory was completed (site area 6,210 m², building area 1,500 m²). In January 1982, capital was increased to 31.2 million yen. In August 1982, the Osaka Sales Office was opened. In December 1986, the company developed a rotary pump. In December 1987, it delivered slurry shield fluid transport equipment for the Eurotunnel construction project. In the 1990s, TOYO Industry continued to innovate. In October 1990, it developed a slide ball valve (slurry outflow prevention device for slurry shields). In June 1993, the head office was relocated to Yanagibashi, Taito-ku, Tokyo. In January 1994, it delivered slurry shield fluid transport equipment for the Tokyo Bay Aqua-Line construction project. In August 1996, the Nagara Equipment Center was completed (site area 11,889 m², building area 1,606 m²). In December 1997, it developed a screw press type dehydrator. In September 1998, it developed a shield comprehensive management system. In May 1999, it developed a slurry jet pump. In January 2000, it developed a rotary crusher. In December 2002, it developed a route management support system (Annai Meijin). In the 2000s, the company expanded internationally. In May 2006, it delivered fluid transport equipment for the Singapore MRT Circle Line and developed and delivered a control system for the SENS method at the Tohoku Shinkansen Sampokubara Tunnel. In July 2008, it became a consolidated subsidiary of Kanamoto Co., Ltd., a company listed on the First Section of the Tokyo Stock Exchange. In July 2009, the head office was relocated to Hamamatsu-cho K-bldg, 1-7-7 Shiba-daimon, Minato-ku, Tokyo. In August 2011, the Chiba Factory was relocated to the Nagara Equipment Center. In December 2011, the Osaka Sales Office was relocated to 2F of Suga Kikai Kogyo Honsha, 3-9-27 Minamihorie, Nishi-ku, Osaka. In December 2015, the company celebrated its 50th anniversary.
