Placement suggestions?

So I know that JET doesn't guarantee placement requests, but I wanted to know of some placement recommendations where it's colder and not insanely hot n humid. I'm from Miami, so I'm more or less used to the heat but I hate being sweaty all the time. I'd prefer somewhere that's rural and a little cooler. So id really appreciate some recommendations. Not too cold not too hot. I know it gets hot all over Japan so I know I can't fully escape the heat lol. I've been recommended prefectures like Nagano, Yamanashi, and Tohoku. Input and advice is appreciated 🙏
