　Kabuchii (scientific name: Citrus keraji var. kabuchii hort.ex Tanaka) is a citrus fruit native to Okinawa, belonging to the tangerine family. The name means “thick skin.
　It is a small orange with a diameter of 4-5 cm, and although it is not very attractive due to its rough appearance, it has a distinctive aroma and a refreshing sweetness. As its name suggests, the peel is thick and floating, making it easy to peel, but the edible portion is small and the yield is low, so its commercial value is not high. It is also difficult to eat because it is a wild variety and has many seeds. Because of its early maturity and rapid acid loss, it is harvested in green slices from October to early November. Production is about 60 tons, most of which is consumed within the prefecture. Wikipedia

　Okinawa's native “kabuchee” was originally cultivated throughout Okinawa, but due to various factors, the focus of cultivation is said to have shifted to Yanbaru (the northern region of Okinawa's main island). It was called “field day tangerine” because the harvest season was in October, which was the field day season in Okinawa Prefecture during the Showa period.　　Translated with DeepL.com (free version)
