Shirahone Onsen, nestled in the Northern Japan Alps, is a cute little hot spring town known for its milky white spring water and lush nature. If you like hiking and relaxing in the onsen afterwards, this is the perfect place for you. With a handful of ryokan scattered along the valley slopes, you can soak in the relaxing waters while taking in the amazing mountain views. According to legend, three-day immersion in Shirahone's waters can keep colds away for three years! I should really stay three days next time..
