Rookie (Sakanaction song)

[4] The single was well received by music critics in Japan, praising the work for its upbeat arrangement incorporating Latin percussion.

[12] On October 23, the band held a live streaming session on Ustream, in order to show their audience the methods they use to create music.

The third package compiled both concerts and added a third DVD, Sakanaquarium 2010 (D), featuring tour documentary and interview footage.

[24] Due to the effects of the 2011 Tōhoku earthquake and tsunami on March 11, 2011, Sakanaction cancelled or rescheduled many of their scheduled radio appearances.

[25][26] Yamaguchi found in his radio appearances that he dedicated very little time to promoting the song itself, instead focusing on messages for the victims of the earthquake.

[27] On March 16, the physical edition of the single was released, featuring the B-sides "Slow Motion" and "Montage".

[30][31][32] A performance of the song also appears on their digitally exclusive live album Sakanaquarium 2012 "Zepp Alive" (2012);[33] a recording of which was present on the DVD disc of the band's "Yoru no Odoriko" (2012) single.

[34] In 2012 the song was remixed by Japanese DJ Takkyu Ishino for inclusion on the group's single "Boku to Hana".

[36] The cover artwork was designed by Kamikene of Hatos and Normalization, who was inspired to create a simple, geometric pattern after hearing the song's style.

[22][37] The single featured a 24-page booklet attached to it, designed by Kamikene with photography by Daisuke Ishizaka, which was created at the request of Yamaguchi, who wanted to stress the importance of physical CDs as a medium.

[43] CDJournal reviewers similarly praised the song's beat that "intertwined howl-like synthesizers and Ichiro Yamaguchi's vocals", as well as the "tightly packed" blend of rock and dance music.

[1] They considered the highlights of the song the "verge of collapse" beats that "broke down the bridge", as well as Yamaguchi's "abstract" lyrics.

[1] Excite reviewers noted the song's basis was club music, that incorporated elements of electro, psychedelic, rock, pop and tribal beats.

[45] The Tōhoku earthquake and tsunami disaster affected the single's availability in stores, as several distribution centers in Eastern Japan sustained damage.

Because of this, the single had a delayed release in the Tōhoku, Kōshin'etsu and Kantō regions of Japan, including the capital Tokyo.

The music video featured scenes shot in the Kaigan-dōri area of Yokohama .
