Other than his distinctive voice, I know Chiharu Matsuyama (松山千春) as the poor guy who lost most of his hair... but I must say he's rocking the bald look with that untidy salt and pepper scruff on his chin - kinda makes him look a little like a walrus though, especially when it grows out.
But with that aside Matsuyama's 8th single from 1980 'Koi', which just means love, pretty much had me with the soft chords of the acoustic guitar and sharp yet gentle whine of the harmonica at the start, giving a sort of nostalgic feel to the song. Definitely a far cry from the rock and roll of 'Nagai yoru' (長い夜) that would come out a year later.
Now that I think of it, this song just gives me the image of the folk singer-songwriter in his early days sitting on a bench in a near empty train station platform at sunset, singing this ballad in a heartfelt way while strumming away at his guitar, probably yearning for that special one to arrive... if she is even coming in the first place! Ah hah hah, now that gives it some extra depth!
Moving on, being one of Matsuyama's self-written and composed hits, 'Koi' did well on the Oricon charts peaking at 6th on the weeklies and managed to stay on people's radars long enough throughout the year (released on 21st January) for it to rank 34th in 1980.
Here's a live performance of Matsuyama from back in the day singing an acoustic version of the song.
