Month of Parturition (臨月, Ringetsu) is the eighth studio album by Japanese singer-songwriter Miyuki Nakajima, released in March 1981.
The album features "Hitori Jouzu", a song released as a lead single in October 1980 and became her second top-ten hit on the Japanese Oricon (since her 1977 chart-topper "The Parting Song").
Month of Parturition topped the Japanese albums chart for two weeks, and marked the number-six on the country's year-end chart of 1981.[1] Also in December 1981, the album received honor of winning the 23rd Japan Record Awards for "Album Best 10", a category acclaimed the ten most magnificent long-playing records.
Along with a follow-up Kansuigyo released in the following year, Month of Parturition has been one of her best-selling non-compilation albums to date, selling over 590,000 copies.
