Umm basically the drop-ins are quite pricey. What you need to do is locate.. like community type centers, but I am not sure how you will accomplish this. Anyhow the rates at these places are very cheap 200-500 yen per visit, and you do not need to worry about IDs or that sort of thing. Otherwise.. bust out your laptop and do some P90x videos at your hotel I guess.
