Japan has largely failed to develop an extensive aerospace industry capable of designing and manufacturing entire aircraft. One explanation has been that the political cum security relationship between the US and Japan precluded the development of an autonomous aerospace industry. This relationship may be changing. Japan has succeeded in gaining extensive sub-contracting work on the new Boeing 787, including technology-rich work on wing design. As such, this paper puts a different take on the concept of path dependence; that it can be a social construction. This paper considers whether technological change in the sector is, however, opening opportunities for Japanese Finns to break free from their current trajectory.
