  • The single was announced on December 25, 2021 on their YouTube subchannel BEYOOOOONDS no Nobishiro.[10] The release date was announced on January 2, 2022 at the Hello! Project 2022 Winter ~LOVE & PEACE~ tour during the first performance of the song "Hamkatsu Mokushiroku".
  • This is the group's first double A-side single. It was also their first release to not include songs for each sub-unit.
  • "Eiyuu ~Waratte! Chopin Senpai~" is a rearrangement of Chopin's Polonaise in A-flat major, Op. 53, more commonly known as the "Heroic" Polonaise.
  • Songwriter Hoshibe Sho ended up writing "Eiyuu ~Waratte! Chopin Senpai~" after hearing Kobayashi Honoka had performed a piano cover of Chopin's Heroic Polonaise at her 2021 birthday event. Before then, production had already had an idea to cover a classical piece to contrast with BEYOOOOONDS' last two cover songs. "Eiyuu ~Waratte! Chopin Senpai~" mainly consists of Chopin's Heroic Polonaise and Chopin's Nocturne Op. 9 No. 2, with a touch of Chopin's Fantaisie Impromptu at the end.[11]
  • "Hamkatsu Mokushiroku" contains wordplay in the lyrics with the similar-sounding phrases "HAMKATSU kuu" (ハムカツ食う; eating hamkatsu) and "Haa... MUKAtsuku" (はぁ…ムカつく; ugh... that's annoying). The music video provides a scenario where angry people can be sated by eating Hamkatsu.[12]
  • There are four different dialogues in "Hamkatsu Mokushiroku": one in the music video of the song featuring Ichioka Reina, Kiyono Momohime, and Satoyoshi Utano, one in the single version of the song featuring Takase Kurumi, Yamazaki Yuhane, and Hirai Miyo, and another two included in the "Atsukiri Hamkatsu Ver." of the music video; one featuring Shimakura Rika, Eguchi Saya and Maeda Kokoro, and another featuring Nishida Shiori, Okamura Minami and Kobayashi Honoka. Additionally, the "Atsukiri Hamkatsu Ver." of the music video included in the Limited Edition SP1 Blu-ray features all four dialogues parts. All four dialogue parts were written by Nozawa Toru.[13]
  • The single's release date is almost exactly a year from their last single's by only one day.
