Redd Arremer's video: PS1 Dosukoi Densetsu - sumo wrestler breeding

A breeding/simulation kind of game. In Dosukoi Densetsu you're assigned with the task of managing a dojo. You purchase sumo wrestlers and raise their abilities by having them perform various exercises. A wandering vendor drops by your dojo every now and then to sell items which help speed up the routine. Mistreating the wrestlers or failing to tend to their needs can make them give up the ghost(happens in the video). The gameplay is entirely menu-based. If the screenshots on the back cover are to be believed, eventually your wrestlers get to perform in a fighting arena. Unfortunately, I never got to that point despite having spent a good couple of hours on this game.
