Kugahara-yu

Opened 60 years ago and recently renovated, Kugahara-yu features a majestic Mt Fuji mosaic on its bathroom walls. The men’s and women’s sides are decorated with different colour schemes (representing the moon and the sun), but you’ll get a chance to experience both as they rotate the changing rooms every two weeks. Regardless of the less than convenient location, it's usually packed with families and kids – in part thanks to the 'junior days' (days when special discounts are offered). It features a spacious bath with massage jets, a warm carbonated bath (from where you can watch TV), hot bath, cold bath, outdoor bath with black onsen water, a steam sauna (free) and a dry sauna (¥200).
