Japanese idol group formed in May 2011 by the Ryuto Artist Farm agency in Niigata in the prefecture of the same name. It was initially made up of Nonoko Satō (Nonno), Mū Ikarashi (MuTang), Tomoe Uno (Tomochy), Yuri Kimura (Yuriri) and Wakana Ōishi (Wakkar). The latter two will leave RYUTist in 2012 and 2016 respectively, while a new member joins the group in 2016 in the person of Miku Yokoyama (Miku-chan). Their first live album, Ryutist Home Live, was released in 2015 and reached number 115 in the Japanese charts. This was followed by three albums in the space of four years: Nihonkai Yūhi Line (日本海夕日ライン) ranked 162nd in 2016, Ryuto Geigi (柳都芸妓) 152nd in 2017, while Falsetto (ファルセット) marks a notable breakthrough in 2020 with a 27th position in the Oricon charts thanks in part to the performances of the titles "Sensitive Sign (センシティブサイン)" (no. 46) and "Kitto, Hajimari no Kisetsu (きっと、はじまりの季節)" (no. 43). 2022 saw the release of a fourth opus, (エン). This climbs to 72nd place in the Japanese charts.
