Shika Wakashū
Shika Wakashū, abbreviated as Shikashū, is an imperial anthology of Japanese waka, compiled c.1151-1154 CE at the behest of the Emperor Sutoku who ordered it in 1144. It was compiled by Fujiwara no Akisuke. It consists of ten volumes containing 411 poems.
The Shikashū is the shortest of the imperial anthologies. Despite Akisuke's ostensibly conservative nature, it is rather eclectic and has a wide variety of poems.
