"The Japanese software market has entered into a traditionally quiet period after the Golden Week national holidays at the beginning of May, with the top ranked title being a Pachinko game which sold only 81,000 units.

In hardware terms, the PlayStation 2 continues to dominate with over 52 per cent market share, leading from the Game Boy Advance which had just under 39 per cent, and the GameCube with just under 8 per cent."
