Japanese market share of the Western game market has been reduced to 20 percent according to an analysis of the Japanese gaming industry by the CESA. The decline is significant as Japanese game development used to maintain a dominant position in the industry especially for home and portable console game development.
The speed of the decline is also noteworthy as the decline has become impossible to ignore during this generation of home consoles which are roughly 2 to 3 years old.
In October of last year, Square Enix president Yoichi Wada declared that Japan had "lost its position" as the leader in the video game industry. These claims are being backed by evidence which shows the market share for Western-developed titles in their own territories doubled between 2004 and 2007 while Japanese game market share has declined.
