"Soaking in baths full of fruit in Japan"
"In Japan, people traditionally soak in hot baths with the yuzu citrus fruit to welcome the winter solstice and protect their bodies from the common cold. During last year’s solstice celebration, children from a local preschool shared a dip in a traditional yuzu tub in the city of Toyooka as dozens of the yellow yuzu fruits surrounded them on the surface, according to Japan’s daily newspaper Asahi Shimbun."
