　Tankan, a popular citrus fruit in Okinawa. It is a subtropical citrus fruit that prefers high temperatures, and the harvest season is from January to late April. Tankan, which peaks in February, is a winter fruit in the subtropics where there is no snow.

　Tankan is characterized by its thick and bumpy skin, with uneven color and black spots mixed in. Due to its thick skin, it can be a bit challenging to peel, but the flesh is orange, soft, and juicy. It is said to have a rich flavor with less acidity than it appears, leaving a lingering sweetness. The photo shows the Tankan I received, and although the season is coming to an end, it is still sufficiently sweet.
　Tankan is believed to have originated in Guangdong Province, China, and it was introduced to the Ryukyu Islands, including Okinawa and Amami Oshima, via Taiwan in the late Meiji period. It is said that full-scale cultivation began around 1934 in the Showa era.
