Sanju Rokunin Kashu

In the 12th century, the poems were transcribed as a compilation for the birthday of Emperor Toba (r. 1107–1123) consisting of 39 volumes and involving 20 calligraphers.

In the 16th century, the works were dedicated to Nishi Honganji which was located in Ishiyama in the Osaka Prefecture.

The temple was later moved to Kyoto and divided, and at this point the works became part of the formal Nishi Hongan-ji National Treasures, where they are still stored.

One (collected poems of Fujiwara no Kanesuke) was altered to another late Heian period manuscript.

The original two volumes were separated and sold to collectors as single leaves in 1929.
