IHI, anticipating the increasing demands for jet engines, decided to bring together in one area various industries from across the country. In 1994 land was purchased in Soma City’s Industrial District, which was developed by Organization for Small and Medium Enterprises and Regional Innovation Japan.
The influencing reasons to acquire land were first, Tanashi Plant’s 50-year-old building that could no longer sustain production demands, and the inability to expand within the urban area. Also, in order to build an innovative plant with high quality, internationally competitive and progressive products, the company needed a building structure that would uphold a significant superiority against rival companies. Furthermore, a hard look toward the future suggested that to support such global strategies, purchasing large land areas was considered indispensable. The company searched all over Japan for the best industrial development, and as a result, Soma City was chosen as the ideal location and a 230,000㎡ area was acquired.
