In Kakegawa City, Shizuoka Prefecture, Japan, the production of the local sugar 'Yosukashiro' continues despite the advancement of cheaper imported sugar. This rare sugar, which can only be produced until late November or February, has a long history dating back to the Edo period. Volunteers revived its production in 1989, and it is now expected to produce 20 tons annually. The sugar cane is grown facing the wind to reach about 2 meters in height, and is also used in the high-grade sugar 'Wasanbon'. The Yokosuka feudal lord is said to have learned the sugar-making technique in Shikoku and brought back sugar cane seedlings. The Yokosuka Shiro Preservation Society was established in 2013 to continue its production. The sugar, sold at Sun Sun Farm, city road stations, and long-established confectionery stores, is popular for its unique flavor and high quality.
