I'm planning to go to Japan from December to January and wondering if there are any gyms I could attend to during my stay.
I am not a Japanse citizen, nor do I have an official address there. I can speak Japanese though.
The best would be a membership that allows me to go there any time during that period, but even something like an X times pass would be acceptable.
I don't need much equipment, a squat rack and a set of free weights are enough.
