I remember when “Sukiyaki” came out in the 60s. Everyone loved it tho we had no idea what it meant.
That makes two of us. The song was HUGE but nobody had a clue. I played the heck out of that 45 rpm when it came out. LOL!
The song has nothing whatsoever to do with food. The title in Japanese is "Ue o Muite Arukō" (when I walk, I look up), and it's about coping with loneliness and depression.
You can find a good recording, with an English translation, here.
