Abstract
Japanese companies have recently lagged behind other nations in many technology fields.
This project is aimed at defining the strategies used by Japanese companies that monopolize the market. This study focused on the interchangeable lens digital camera industry, where five Japanese companies have been dominant.
To understand these companies' technology-based competitive strategies, data related to patent, especially in their core technologies such as lenses, mirror boxes, imaging elements and imaging processing were gathered and analyzed.
Data analysis revealed marked differences in each technology-based competitive strategy?even between Japanese companies?and that these companies are pursuing different approaches.
