    Become more beautiful with the "Beauty Bath"

    The natural hot spring here at Izumi Tenku no Yu is a "beauty bath" with a strong cleansing effect that removes dead skin cells and dirt from pores. Generally, the stronger the cleansing effect, the more likely it is to dry out the skin. However, our hot spring has a high salt concentration, so it also has heat retention and moisturizing effects. The "salt pack effect" keeps your skin hydrated while promoting blood circulation even after bathing. In addition to smoothness and whitening, it also provides moisturizing care. Please enjoy our hotel's proud beauty bath to your heart's content.

    Bathing method to make your skin moist
    ①
    Women should remove their makeup first
    ②
    Relax in the hot water

    Relax and soak in slightly warm water (38-41°C) for 20-30 minutes. This improves blood circulation and boosts skin metabolism.

    ③
    Gently wash your body

    Lather up the soap or body wash well and wash your body. Do not scrub vigorously as this will remove the new stratum corneum and cause dryness.

    ④
    Once again, soak in the water

    Take one last relaxing soak in the water, or finish off with a full body massage in the shower.
