What Is “Kusa no tsuyu shiroshi” (草露白)?

"Kusa no Tsuyu Shiroshi" (草露白) is one of the seasonal expressions in the traditional Japanese calendar known as Shichijūni Kō (72 microseasons). It falls in early September each year and marks the first microseason of Hakuro (白露, "White Dew") within the Nijūshi Sekki (24 solar terms). The phrase literally means "the time when dew on the grass glistens white," describing the season when morning dew begins to sparkle in the cooler autumn air. Since ancient times, it has been appreciated as a sign of the approaching fall season, when temperatures begin to drop in the mornings and evenings. Around this time of year, the intense heat of summer gradually softens, and subtle signs of autumn start to appear in grasses, flowers, and trees. In the early morning, tiny drops of dew gather on the fields and shimmer white in the sunlight, creating a tranquil and beautiful scene. As an expression of Japan's uniquely delicate sensitivity to the changing seasons, "Kusa no Tsuyu Shiroshi" is also sometimes used in haiku and traditional waka poetry. The Shichijūni Kō calendar was created to capture the subtle transitions of nature in greater detail, and "Kusa no Tsuyu Shiroshi" is considered one of the important seasonal markers that herald the beginning of autumn. Even today, it continues to attract people who value an awareness of the changing seasons, and it is especially popular among those interested in traditional Japanese culture, seasonal customs, and classical calendar traditions. By learning the meaning of "Kusa no Tsuyu Shiroshi," even an ordinary morning landscape can be seen as filled with seasonal beauty. For anyone wishing to experience Japan's four seasons and the world of Shichijūni Kō (72 microseasons), "Kusa no Tsuyu Shiroshi" is one of the elegant seasonal words that beautifully evokes the arrival of autumn.
