AAKER, author of this book, provided me the insight for brand building. The character of this book is every his insights have been written with case-studies. These made me understand easier his thought about branding. Into his thought, I was focused on the plan to reduce the investment for advertisement. These investments became the issues on both U.S. and Japan BtoC net companies’ branding approach. If I find the negative on this book, He has not cover Japanese case. Why? Japanese too domestic economic environment cause it?. Anyway, I expect his next latest book.
