Tsukubashū (菟玖波集, "The Tsukuba Anthology", compiled c. 1356) was the first imperial anthology of renga.
[1] The collection was compiled by Nijō Yoshimoto.
Provincial lord Sasaki Takauji played an active role in its production with 81 of his poems appearing in the final version.
[1] In addition to courtly renga, the anthology contains, in Book 19, the earliest known collection of haikai no renga.
[2] The title of the work refers to Tsukuba, a location in the east Japan at which, according to the Kojiki, Yamato Takeru and an elderly interlocutor composed a two-part poem together, this story being where practitioners of renga traced their tradition's origins.
