Here are some additional thoughts based on your analysis:
The use of contrasting imagery: The first two lines paint a picture of someone emaciated and desperate ("imadewa-yubiwano-mawaruhodo yasete-yatsureta"), while the third line introduces a more hopeful and romantic image ("Tabijino-hatemadee tsuitekuru"). This contrast could be interpreted in several ways, perhaps representing the character's journey from despair to hope, or the juxtaposition of their physical state and their emotional longing. The flower symbolism: The cape jasmine flower (kuchinashi) is often associated with purity and innocence, which could symbolize the character's idealised image of the person they love. The repetition of "kuchinashi" emphasizes this connection and creates a sense of longing. The historical context: The song was released in 1973, which was a time of significant social and cultural change in Japan. It's possible that the lyrics reflect the anxieties and desires of people during that period.
Overall, the lyrics seem to be about unrequited love and the power of memory. The use of sound imagery and contrasting themes creates a melancholic and evocative atmosphere.
