OMO7 Asahikawa 'Sauna Plateau' is an exclusive sauna facility for guests, integrating the 'totonou habit' into urban stays. It features a dry sauna at around 90°C and a mist sauna filled with the scent of vihta, designed for deep sweating by combining humidity and heat. The 16°C cold plunge bath with natural underground water and vibra sharply cuts the heat, and the outdoor air rest clears the mind. Surrounded by the soft light and solid wood typical of northern regions, it functions as an 'urban sauna retreat' to switch between travel and work modes.
