Beatmaniaiidx.com was supposed to be mainly about the great music game BeatMania IIDX (7K) which is an “upgrade” of BeatMania (5KEYS). BM is the first musical game from a series called BEMANI. As you can see everything on this blog has to do with either BEMANI or other music games. BEMANI games are produced by a company named KONAMI. So you wonder where the number 573 is hidden in the word KONAMI?

It’s easy actually. KONAMI is a Japanese company. Isn’t there something more to the name? Well, there is. Five is said “go” in Japanese and it can be changed to voiceless version “KO”. Seven can be said nana and from there comes the “NA”. “Number” three can be described by mitsu from which comes the last syllable “MI”. From this 573 was born and the company is also known under this number.

573 number can be found in KONAMI games. For example both The Legend of Max and Max300 from DDR have max combo exactly 573.
