Muchi
Muchi (ムーチー or 餅 Mūchī), also known as onimochi (鬼餅), is a type of soft confectionery made of pounded glutinous rice and eaten in Okinawa Prefecture. Muchi is the Okinawan dialect of "rice cake", sometimes called "Casa Muchi" from the fact that wind in the leaves of shell ginger. After the muchi is seasoned with brown sugar, white sugar, purple yam and so on, it is wrapped and steamed.
In December, it is eaten as a lucky charm for the prayer of health and longevity. Also, from the end of January to early February of the Gregorian calendar is the coldest season in Okinawa, and it is called “Muchibisa” over this period in Okinawan dialect. “Families will prepare Muchi together, making dozens of individual ones called Kassa Muchi, and may even make a huge one, called Chikara Muchi, and eat the big one together. The Muchi treats are tied up in string and hung from the ceiling as pretty decorations in the house."[1]
The origin of the "Onimochi" is from a folktale of the main island of Okinawa. It was written about 800 years ago in “Kyuuyo”, which was compiled in the 18th century at the time of Nao Takashi reign.[2] It states that a man who moved from Shuri city to Osato city was attacking humans and animals and became a demon. His younger sister was sorrowful and put iron nails in Muchi, which the man loved and fed. Then, she pushed away the brother, who was weakened, to the sea and killed him. From this Okinawan tale, it is also called “Onimochi” because Muchi was used to exterminate an ogre.
