This book is targeted at business executives of companies: • approaching the Japanese Market, • reviewing their options in terms of Japan Entry Strategy, • already exporting to Japan (Indirect Sales) or, • already established and doing business in Japan (Direct Sales). Here, I do not focus on the cross-cultural side of things (please check my other books for that) but I rather cover in details the business side of things in Japan. First, I give the reader some insight into selected markets in Japan, as well B2C as B2B. Second, I show how to adapt to the local specificities, Industry by Industry, and I give some tips and guidelines for building a successful (B2C and B2B) Marketing Mix in Japan. Third, I introduce and analyse the various Entry Strategies available to foreign companies keen on developing their business in Japan.
