IB Daiwa Corporation (株式会社アイビーダイワ) is a Japanese multi-national business conglomerate with headquarters in Tokyo. Daiwa's primary interests are in the resources and energy business in the United States and Australia; and the company is also involved in the food business.[1]
History
Daiwa was started in 1947 as a manufacturer of industrial use machine sewing thread and twisted yarns.[2] The company subsequently diversified.[3]
Following the 2011 Tohoku earthquake and tsunami, the series of Fukushima I nuclear accidents included the discovery of a roughly 20 cm crack in a concrete-lined basin behind the No. 2 reactor's turbine building. Daiwa provided a water-gel polymer mix which was introduced into the basin in an attempt to plug the leak;[4] but the attempt was initially unsuccessful.[5] In due course, the Tokyo Electric Power Company (TEPCO) announced that an injection of 6,000 litres (1,600 US gal) of polymer coagulant into the pit did mitigate the leaking;[6] however, the International Atomic Energy Agency (IAEA) and others credit additional factors as well.[7]
