I live in Nagano Prefecture.

I searched around, but there were very few women in Nagano. As you’re thinking, it would probably be best to use the club when you’re traveling to Tokyo for work. For questions like this, it may be better to ask during your interview with Universe Club, since they can tell you the actual number of women available. They weren’t pushy about signing me up, so I’d recommend going in for an interview without worrying too much.
