Wow! Kabosu! I’ve been looking for one forever but thought they do not exist. Even sent UC riverside a request to reintroduce. I have Yuzu, shikuwasa, and sudachi but live in the Bay Area, California so do not have struggles with the freeze. My interest in Japanese citrus comes from strictly a culinary perspective as they go well with seafood and certain soups. Gives me hope they might be available down the road.
