For my first entry here, I chose to cover Momoe Yamaguchi's (山口百恵) "Cosmos", which was released as a single in October 1977 and written and composed by folk singer-songwriter Masashi Sada (さだまさし). It became one of the singer's signature hits, selling around 500,000 copies total and became the 35th-ranked single of 1977 and then the 92-nd ranked single of 1978. Sada would later record his own version of the song for his album Shikashu (Anthology).
On the other hand, I think the song really befits its writer. I was first introduced to Masashi Sada through his soundtrack for the early-80's drama Kita no Kuni Kara and since then would associate his work with warm and homely family imagery. He specializes primarily in folk ballads that express traditional Japanese fondness for communal and family unity. Even the 23-year old me who's never been to Japan feels inspired to see my old relatives who live far away. Just listen to his version of "Cosmos" below and you'll see how much care he put into it.
