Born December 16, SHIHO is a japanese singer-songwriter from Sapporo, Hokkaido. She was active in I've from 2000 to 2006.
SHIHO was affiliated to I've Sound from 2000 to 2006 and became well known for performing songs like Belvedia, Ever stay snow, Kiss the Future, birthday eve and Days of promise, songs that are now considered I've classics. From March 2006, she graduated from I've to focus on her own musical activities. In 2015, she made a brief return to I've, participating in their 15th Anniversary Celebration Girls Compilation The Time ～12 Colors～ with the song Dark of the moon. In 2020, I've sound creators released a series of videos entitled "Composer, talk. In 3 minutes!" (作曲者(composer)は、語りたい。3分で！) on their YouTube Channel to talk and comment about songs requested by fans, with each video contemplating one song and one guest (voice only). SHIHO participated in three videos with Kazuya Takase, where they talked about PREY -Remix-, Belvedia and World meets worlds.
Since 2006, SHIHO released several discs under the indie label STARAVID, established by her younger brother ￥utaka. From later 2012 to early 2017, there was no activity from STARAVID, except for 2015, when she released her first best album with also some new songs under Visual Art's. The second disc included only STARAVID songs, the first disc mainly consisted of original songs composed and arranged by various artists, including Eiko Shimamiya and, at that time, the newcomer I've sound creator NAMI, who previously was a vocalist at Larval Stage Planning unit. While it was released under STARAVID label, there was no new song produced by ￥utaka at that time. In later 2017, ￥utaka and SHIHO returned with STARAVID and her new single "SPEAK about start" was released at the indie event M3. That release also marks SHIHO's debut as a composer.
From later 2012 to early 2017, she was mainly active with the musical circle WOM, formed by wata, Grok and MUSIKADeLIK, who were in charge of compositions and arrangements, while SHIHO was in charge of vocals and lyrics. Their works predate the growing wave of digital releases, having been made worldwide available for streaming and download through Bandcamp immediately.
In 2018, she joined Eiko Shimamiya and Kanako Ito (on vocals) and Makou (on sound production) in a new musical circle called Quadrifoglio, releasing their first mini-album on April 29, also at M3. While their first release consisted only of solo songs, their second mini-album, released in 2019, included some songs with the three vocalists singing together, now elevating the Quadrifoglio concept to be recognized also as a vocal unit. From their third mini-album, released in 2020, to the present, they've only sang under the vocal unit Quadrifoglio name.
