The song was praised by music critics, who likened the classical phrases and choral vocals to Queen's "Bohemian Rhapsody" (1975).

The band gained exposure in Hokkaido after winning the audition to perform as a newcomer artist at the Rising Sun Rock Festival in Otaru in August 2006, and after demos of their songs "Mikazuki Sunset" and "Shiranami Top Water" performed well on College Radio Japan Sapporo.

The album was primarily promoted with the song "Mikazuki Sunset",[2] which was widely played on radio stations in Hokkaido in May.

[4][8] Guitarist Motoharu Iwadera was the member who spent the most time contributing to the production of the song, and the band tried to have as much fun as possible with the arrangement.

Iwadera added Queen-style guitar riffs to the song, and the group decided to add chorus work in the style of Queen.

[11] The band attempted to incorporate all of Sakanaction's musical aspects into the song, by including folk, dance and pop elements.

[26] "Night Fishing Is Good" was shot in a single day during the new year period in 2008 at the Arata River in Gifu, in two takes.

[11][28] Yamaguchi asked Mori to create a music video showing him in the act of genuinely catching a fish.

[29] The video begins by showing Yamaguchi fishing at dawn on a bridge in a suburban area, while he lip-synchs to the song.

The third sequence shows Yamaguchi capturing the fish, and ends with him triumphantly holding up the Asian carp he had just caught.

Haruki Terada of Musica praised the song's classical phrases and choral vocals, likening it to Queen.
