Anytime Fitness is a global fitness gym chain, and there are more than 1,100 gyms throughout Japan. If you are a member of Anytime Fitness in your home country, you can use any Anytime Fitness gym in Japan for free. It's ideal if you're visiting several cities in Japan and want to save money because a day pass at a local gym usually costs $20-30 per visit. And it is open 24/7 which is very convenient for travelers. And the rules of Anytime Fitness in Japan are the same as those in your home country. You can use the same electric key to enter the gym.
There are a few things to note. Firstly, you have to be a member of Anytime Fitness for more than 31 days in your home country. Secondly, even though there are many Anytime Fitness gyms in Japan, many of them are NOT in convenient locations for tourists. In my view, only 5 % are in convenient locations for tourists. Please see my recommendations below for gyms in convenient locations for tourists in each city.
