Yukata is the summer kimono made of lightweight cotton. The word “yukata” is the abbreviation for “yu (bath)-katabira (under clothing).” In the Heian period (794-1192), the noblemen wore yukatabira to prevent heat when they took a steam bath. Later in the Edo period (1603-1868), when a steam bath was replaced by the bathtub as is used today, Yukata, which absorbs sweat and has permeability to air, came to be worn as a summer kimono, a dressing gown, or night attire. At the present time, it is the most popular night wear at a Japanese ryokan (inn). The fabric designs vary from the traditional indigo plant patterns on a white background to more colorful designs. Polyester or blended fabric is also used. Since Yukata is easy to wear, it is the most popular kimono wear. The scene with people walking in Yukata is one of the charming sights of summer in Japan.
