In the second section of this book, we will focus on the mobile industry in Japan and Europe, specifically in Finland and the United Kingdom. The goal is to use the various theories, models, and frameworks described in Section I to understand why the mobile industry looks like it does today and where the industry is going. Let us start with a brief overview of the mobile industry in Japan. The emphasizes is on the word “brief” because the intention is not to go very deep into the special characteristics of the Japanese way of doing business; neither does this book offer an in-depth description of mobile business in Japan — there are far better books and research reports for that. However, this chapter tries to pinpoint the features that are the most important for comparison of the business models in Japan and in the two selected European markets.
