Disappointing price compared to Amazon from other countries

I am very happy with the content of the book itself.

However, I am not quite satisfied with the price on Amazon Japan compared to that on Amazon in different region. The price is twice as much as the price in America, especially with the advantage of the current exchange rate. If you buy the the book on Amazon America and have it sent to Japan, the converted price is still even cheaper than the price listed on Japanese site. Thus, I am actually disappointed about this.

The book is a great access to an amazing leader and innovator of the IT age. After all, it is worth buying.
