In Japanese, the month is known as rokugatsu (Japanese: 六月) or traditionally minazuki (Japanese: 水無月).
Although the spelling 水無月 can suggest a month without water, since the character 無 normally means "absent" or "not exist", it is used in 水無月 only as an ateji for a possessive particle equivalent to no, giving the sense "month of water". This is a reference to the flooding of the rice fields, which requires large amounts of water.
In Kyoto, minazuki (水無月) is also the name of a triangular uirō sweet topped with adzuki beans, traditionally eaten in summer.
Yudu is celebrated on the 15th day of the 6th month in Korea.
Nagoshi no harae, the summer great purification, was traditionally performed on the last day of the 6th month in Japan.
