How Big is Japan's Game Market towards the Whole World?
	As you know, Nintendo, selling Wii and NDS, and Sony Computer Entertainment, selling PS3 and PSP, are Japanese companies. Of course they have departments in foreign countries, but basically they are Japanese.
	Thinking this way, it seems that Japan has an important position in the game market.
	Though Japan is the source of consoles, if we compare Japan's homeland market with overseas market, it is another story.
	What do you mean?
	Japan's homeland market is less than 20% of the whole world's game market. The fact is it is not big at all.
	So our consoles are hot worldwide, but our market share is less than 20%...
	World's population is 6.8 billion nowadays. Japan's population is 0.13 billion, just 2% of the world. You may feel that less than 20% is quite a share, but our share is much bigger in the past. The value of Japanese market is decreasing.
	As a result, we always heard about the necessity for Japanese game makers to explore the world.
	Especially from SQUARE ENIX and CAPCOM. Even though some large makers won't talk about this publicly, they should thinking the same thing.
	CAPCOM, with her Biohazard (Resident Evil) series and Street Fighter series, has became a common example of Japanese company which gain great success overseas.
	Japan's homeland market can no longer grow, some feel that we are reaching the ceiling. On the other hand, overseas game users are just a small portion in the past. Nowadays, new users are increasing when they touch Nintendo's NDS and Wii. This trend is strengthening.
	Though the same thing happens here in Japan, difference in population and the large number of already-exist game users make it difficult to increase new users as effective as the foreign market.
	Japan remains the same while the worldwide market expanding, as a result position of Japan's market drops. Though we can't judge this situation good or not simply, as a Japanese it is quite lonesome.
	That's right...
	As said above, you guys can grasp the Japanese market as less than 20% of the world.
