About TakenakaEdit

The company's website claims it to be the oldest firm of that type anywhere in the world,[2] since the demise of Kongō Gumi which was substantially older.[3] Both companies originate from a family of architect-carpenters (Miyadaiku).

In 1610 Tobei Masataka Takenaka (竹中 藤兵衛正高), a shrine and temple carpenter, started a business in Nagoya. The business continued as a family business and built some of the first Western-style buildings during the last half of 19th century, most of them in Nagoya. In 1899 Toemon Takenaka (竹中 藤右衛門), 14th generation descendant of the original founder, established a branch office in Kobe and founded Takenaka Corporation as an official company.

The company grew more and more during the 20th century, its capital in 1909 was about ¥100.000, ¥6 million in 1938, ¥1.5 billion in 1959 and ¥50 billion in 1979; nowadays, Takenaka Corporation is a multinational company with offices in 18 different countries. Its president is Toichi Takenaka (竹中 統一) (June 2004).

The company is now regarded in Japan as one of the "Big Five" contractors ranked with Kajima, Obayashi, Shimizu and Taisei, and has a long history of designing buildings. The firm has built some of the most important buildings in Japan, including the Tokyo Tower, the Tokyo Dome (the first large-scale stadium with air-supported membrane roof in Japan), the Fukuoka Dome (Japan's first large-scale stadium with retractable roof), and the Kobe Meriken Park Oriental Hotel among others.

Among its proposals is the Sky City 1000 project.

It reconstructed the Suzakumon in Nara.[4]

  • On November 19, 2007, during the construction of a 27-story (94 meter high) highrise condominium in Minato, Tokyo, the whole 8th and 9th floors of the building had to be dismantled and rebuilt because reinforcing steel of insufficient strength had been used.[5][6][7]

Takenaka and Airtech were issued a summary indictment by the Osaka prosecutor's office for violating the Industrial Safety and Health Act.[8]
