oh yeah I forgot about badminton, I play badminton ( if I can) weekly. There is a sport center near my area, its only 200yen/person to rent a court and its good for 1.75 hours

there is also a swimming area , I think its around 700yen now, but there is no time limit and there is a spa and sauna inside, other swimming pools are around 200-300yen and is good for 1-3 hours

another is cycling. The naniwa cycling course , which is I think more than 10kms is good for cycling or jogging

also if you are in Osaka, there is the IOC ( international Outdoor club ) which does a lot of outdoor sports and they also have a sister club in Tokyo..
