Minoru Shimizu (清水みのる) had written the lyrics and Haruo Kurawaka (倉若晴生) had composed the music. Together with Batayan, the three had spawned a number of other hits like "Wakare Bune" (別れ船) - probably the opposite of "Kaeri Bune" - and "Shima no Funauta" (島の舟唄) - his debut single.
With the extra number of times I have listened to "Kaeri Bune" while writing this article alone, I feel it slowly latching on to me... I think. Wonder if it'll have that "Wakare no Ippon Sugi" (別れの一本杉) effect. (Noelle from 30/12/16) Yup, it's finally latched on - it was only a matter of time.
Oh my goodness, it's Batayan without his trusty guitar! He looks so incomplete without the instrument - it's as if he lost an arm or something.
