(henceforth referred to as Kashū
) is a poetry collection compiled by Nakagawa-Tsunetada and reprinted in another collection Seisho-shū
. It consists of 1,566 poems by classical literature scholars and Shinto priests, 366 out of which are “chōka” poems. Interestingly 96 out of these 366 poems are borrowed from Yasoura-no-tama
, a poetry collection edited by Motoori-Ōhira. In addition to them many other songs by Motoori are also selected; they totally account for about 60% of the whole “chōka” poems in Kashū
. Obviously Nakagawa held Motoori in such high esteem that, while trying to make his original collection, eventually he couldn’t resist Motoori’s poetical influence to the extent of including a great number of his poems in it.
