Although the professional sumo tournament is going on in Tokyo, it is possible that an amateur bout or exhibitition is going on locally in the Kansai area. You would need someone local to check in with the Osaka Gymnasium or Sakai Ohama Sumo stadium though.
I could give you a list of places and things you can do out of work in the area, as I have lived there (and was just there last week); but you give no clues as to where your interests lie or what you would like to see. As mentioned, starting with a guidebook and asking for more details or suggestions based on what you have read would be the best.
