Advice on Homestay?

18M here. I'm looking into doing a homestay in a year for anywhere from 6 months to a year just for fun (no plans on moving to Japan). Looking online, it seems that people have a hit or miss experience with homestay depending on who the host family is. For people who have done a homestay before, any advice on where to look and how to find a good host family? Also, anything else I should know before doing a homestay or if it's a good idea or not?

ありがとうございます🙏
