Utada Hikaru Science Fiction Album Vinyl, Disc 1, Side A then Side B

"Lemon" serves as the theme song of the Japanese TV series "Unnatural". Kenshi Yonezu told Oricon News in March 2018, "My previous commissions have been for anime and movies, things I have some familiarity with myself, but I've never watched many dramas. That's why it's a little embarrassing and strange-feeling to hear my singing during a TV drama. [...] It gets played during great scenes, so I feel the love from the drama's staff. I'm happy to know about and be part of such a beautiful production."

"Sukiyaki" is a term with absolutely no relevance to the song's lyrics, as sukiyaki is a Japanese beef dish. It was used in the song name only because it was short, catchy, and recognizably Japanese.

The original title "上を向いて歩こう" means "I Look Up When I Walk". The lyrics tell the story of a man who looks up and whistles while he is walking so that his tears will not fall.

This is the only Japanese song to hit #1 in the United States. Moreover, it is one of the best-selling singles of all time, having sold over 13 million copies worldwide.
