About TakenakaEdit

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 in Japan during the last half of 19th century, most of them in Nagoya. In 1899 Toemon Takenaka (竹中 藤右衛門), a 14th generation descendant of the original founder established a branch office in Kobe and founded Takenaka Corporation as an official company.

The company grew during the 20th century; its capital in 1909 was about ¥100,000. This rose to ¥6 million in 1938, ¥1.5 billion in 1959 and ¥50 billion in 1979. Today, Takenaka Corporation is a multinational company with offices in 18 different countries. The current president is Toichi Takenaka (竹中 統一) (since June 2004).

The Takenaka Corporation claims to be the oldest operating firms of its type in the world. In 2006 Takenaka acquired competing family architect-carpentry business (Miyadaiku) Kongō Gumi which had been in operation for 1,427 years.[2][3]

The company is now regarded in Japan as one of the "Big Five" contractors ranked alongside Kajima, Obayashi, Shimizu and Taisei. 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 an air-supported membrane roof in Japan), the Fukuoka Dome (Japan's first large-scale stadium with a retractable roof), and the Kobe Meriken Park Oriental Hotel among others.

Among its current proposals is the Sky City 1000 project.

Takenaka reconstructed the Suzakumon in Nara.[4]

Insufficient reinforcementEdit

  • 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 the reinforcing steel used was of insufficient strength.[6][7][8]

Industrial accident cover-upsEdit

  • According to a report of December 28, 2007, a 52-year-old foreman of a Takenaka condominium construction site in Fukushima ward, Osaka, reported an industrial accident in which a falling concrete hose seriously injured a worker of sub-contractor, Airtech Co., Ltd. The accident was reported as having happened at a different demolition site that the foreman was also in charge of. Takenaka and Airtech were issued a summary indictment by the Osaka prosecutor's office for violating the Industrial Safety and Health Act.[9][10]
