Sora Tob Sakana

sora tob sakana (means “fish flying in the sky” in Japanease) were Japanese female idol group, whose nickname is “Osakana” (means “fish” in polite language). The final members were Kanzaki Fuuka (神﨑風花), Teraguchi Natsuka (寺口夏花), and Yamazaki Mana (山崎愛).

They were formed on 21 July 2014 and the founding members were Kanzaki, Teraguchi, Kazama Rei Malaika (風間玲マライカ), Sato Mio (佐藤美緒) and Konishi Yuiko (小西結子). In 2015, Sato and Konishi left the group, and Yamazaki joined as a new member.

From the song "クラウチングスタート" (crouching start) debuted in January 2015, Yoshimasa Terui (Haisuinonasa, Siraph) had been in charge of music producer. Terui's complicated music incorporating elements of post-rock, mathrock and electronica, and the contrast of four young voices had brought a hot topic.
Their first indie single "夜空を全部" ‎(all of the night sky) was released on October 2015 and the second indie single "魔法の言葉" ‎(magical words) on February next year. The first full-length album "sora tob sakana" was released in July 2016.
In May 2018, a mini album "alight ep" was released, debut from Warner Bros. Home Entertainment, a label they transferred to.

In May 2019, Kazama 'graduated' from the group and the remaining three continued the group until 2020.
In May 2020 they announced that they would split on 6 September 2020, and at the final concert they played 50 songs (all that they'd ever released) during 4 hours of performance.
