　Also written as "shikwasa" or "shikwasa.　Japanese name: Hirami lemon, scientific name: Citrus depressa, is an evergreen shrubby citrus fruit of the tangerine family (Wikipedia, the free encyclopedia for scientific names). It is a small citrus fruit native mainly to Okinawa, with greenish skin, highly acidic while unripe, and moderately sweet when ripe to yellow, but still more acidic than the tangerine and similar to the lemon. Typical Shikwasa strains are Ishikunibu (stone 9 years old tree), Husubuta (thick navel), Tanebuto (large seeds), Mikangwa (small tangerine), Ingwakunibu (dog 9 years old tree), Hijakunibu (goat 9 years old tree), Kaaachi (thick skin), Kaabishee (thin skin), etc., and their fruit sizes There are also several other varieties.

　Shikwasa was once used as a substitute for detergent to wash bashofu (Japanese banana cloth).　In recent years, the nobiletin, a type of flavonoid found in shikwasa, has been attracting attention and has become a popular fruit.　In Okinawa, shikwasa is not only a health food, but is also used in many other products from seasonings to confectionaries.　Translated with DeepL.com (free version)
