Tonight is Chushu no Meigetsu
Today, September 13th is the day to enjoy the full moon. Because today is August 15th of the lunar calendar and, according to a Japanese tradition, this is the night when the moon shines at its fullest and most beautiful.
In Japanese, the day is called “Jugoya (十五夜).” It is also known as “Chushu no Meigetsu.” Jugoya means “full moon night.” It’s a custom to make offerings at home altars and admire the moon at a party.
The custom of Jugoya was imported from China during the Tang Dynasty. The custom spread in Japan during the Heian period (794 – 1185), first among upper classes and then among farmers who started the custom of giving offerings to deities, specifically to pray and ensure a good harvest of rice. The classic offering is Tsukimi Dango (月見団子), which are round dumplings offered 15 a time and often arranged in a pyramid-shaped pile.
