It has hitherto been considered that “Haru no yo” was composed by Miyagi Michio (1894-1956) in 1913 as his Opus 2, preceded only by his maiden work, “Mizu no hentai”. The composer himself, however, asserts that his Opus 2 was “Kara-ginuta” of 1913, and that “Haru no yo” was his third piece. Since he also mentions that he was indebted to a work entitled “Sagano no shirabe” for inspiration in composing “Haru no yo”, confirming the existence of “Sagano no shirabe” and inquiring when Miyagi had the opportunity to become acquainted with the piece is of vital importance in elucidating the situation in which “Haru no yo” was composed. Recently the jiuta performer Nakai Takeshi confirmed that a transmitter of a work entitled “Saga no shirabe”, a koto player named Harada Etsuko, lives in Tokushima. This “Saga no shirabe” was tentatively identified as Miyagi's “Sagano no shirabe”. Subsequent investigation by the present author has made the following points clear.
1) “Saga no shirabe” was composed either by Tomizaki Kengyo (d. 1844) or Tomihara Kengyo (d. 1877), both of whom were from Tokushima.
2) Miyagi learned “Saga no shirabe” from Ota Wasaichi, a koto player from Tokushima, in January or February 1914.
3) The piece Miyagi calls “Sagano no shirabe” is actually “Saga no shirabe”, a koto work transmitted in Tokushima.
4) “Haru no yo” was composed in the spring of 1914 with inspiration from “Saga no shirabe”, thus confirming the composer's own statement that “Kara-ginuta” of 1913, and not “Haru no yo”, is his Opus 2.
