"Lemon" is a song by Japanese singer-songwriter Kenshi Yonezu, released as a single through Sony Music Entertainment Japan on March 14, 2018.

Even the day before recording, he was still writing the lyrics, the last two sentences "Like one half of a fruit sliced in two, even now, you are my light" suddenly appeared in his brain and he said, "Ahh, so this song really was "Lemon.""

He focused on liveliness and freshness of a lemon, giving it an image quite unlike what's typically associated with death.
