What never changes through countless ages is the sweet flag, wet and fragrant with the drops of the early summer rain. In the sweet flag that blooms fragrant every Fifth Month, the poet finds something everlasting and imbues it with a spirit of celebration.
From poem 127 through poem 134 in this book come poems on the sweet flag, which was hung from the eaves and whose roots were compared for length at the Tango festival on the fifth day of the Fifth Month.
