In a bid to get in shape so I can start wearing those Woman's Egg outfits, I've decided to go to the gym more often.
Niimi has two gyms. One is called Genki Hiroba, and is situated a 25 minute easy cycle away at the other end of town. It's a huge modern complex with a training room, aerobics classes, heated pool, onsen, massage chairs, and who knows what else. I hear they're having special Billy's Bootcamp classes every weekend since the craze recently hit Japanese infomercials. I've never been there. There's a sign on the door stating that if you have been tattooed, you are not welcome. That, plus the membership fees are ridiculous.
Instead, I'm going to the Shimintaiikukan, or Citizen's Gym. Located on top of a mountain a 20 minute cycle from home, it's only 100 yen per visit!
Apart from the deserted training room with antiquated machinery, there's an outdoor swimming pool open in summer, baseball and soccer fields, and.....that's about it. You can hire ping pong tables whenever you like, and there are social games of volleyball and badminton and I don't know what else held on a weekly basis.All mine to use whenever I want.

A funny thing about Japanese gyms is that they all have these old-fashioned vibrating belts. And yes, I've seen people use them.
Just in case you can't figure the equipment out, there are handy instructions about the place.
And if you overdo it, there's a defibrillator at reception for your convenience.
