Kojiro Taigu is a stand-alone music game program with horizontal scroll developed by toach. The latest version is 2.92, which features that you can write your own score and make your own appearance theme package (skin). So there will be all kinds of skins on the internet, and each player can choose his favorite skin.

Author toach positioned the program as a simulation program of Taigu Daren series games developed by NBGI (pictured), and the game's Taigu mode play and scoring method are exactly the same as Taigu Daren's. However, due to Japan's national conditions and other reasons, the original version released by the author cannot contain the original image or similar image of Taigu Daren's game, resulting in a simple interface of the original version. The player's self-made skin effectively makes up for this deficiency.
