Yesterday was 冬至in Japan. The definition of 冬至(Tokuji)is, kind of we are middle of winter, but we will be preparing for colder weather. We generally soak into 柚 yuzu bath. It makes us keep wormer. The peeled area is full of Limnine, and also inside are full of vitamins. The fragrance makes you feel relaxed and as well as better circulations.
