BiSH ("Bish" ビッシュ), also known as Brand-new idol SHiT (Shinsei Kuso Idol, 新生クソアイドル), is a Japanese idol group that was founded in 2015 by their manager Watanabe Junnosuke.

The group was conceived as a successor to BiS, whose first incarnation had disbanded the previous year but have since developed their own identity.

History Edit

2015 Edit

In January 2015, Watanabe Junnosuke announced his plans to restart BiS and opened auditions to find members. In March, Yukako Love Deluxe, Cent Chihiro Chittiii, Hug Me, Momoko Gumi Company and Aina The End were announced as members of BiSH. The members' faces were obscured with black contact lenses and could not be revealed until they each attained 4,444 followers on Twitter.

The song "Spark" was released for free through Ototoy as a demo by Watanabe and again a week later as a final version with the group's vocals.

Not long after Spark's release, Yuka withdrew from the group due to anxiety.

Original lineup

In April, BiSH released a music video for the song BiSH: Hoshi ga Matataku Yoru ni, and more songs were released for free in the lead-up to the release of their debut album, Brand-new idol SHiT, on May 27th.

On May 31st, BiSH held their first one-man live, THiS iS FOR BiS. During the show, they announced auditions for new members and a single to be released in September.

In August, BiSH performed at Tokyo Idol Festival for the first time, however, their second day of performances was cancelled due to misbehaviour from their fans. The same happened to their sister group, POP. Despite this, both groups continued to be invited to Tokyo Idol Festival every year since.

On August 5th, Hashiyasume Atsuko and Lingling were announced as new members. Like the previous generation, their faces were obscured with contact lenses until they received more Twitter followers than Watanabe. However, Watanabe soon got impatient and lowered the follower amount to 5000. The first single with the new lineup, OTNK, was released September 2nd.

2016 Edit

On January 19th, on the final show of their IDOL is SHiT Tour, they announced their major debut with Avex Trax in May. The next day, their second album and last indie release, FAKE METAL JACKET, was released.

On May 5th, BiSH released their major debut single, DEADMAN.

On May 16th, Hug Me announced her graduation, citing family reasons. At the same time, auditions to find a replacement were announced. Hug Me graduated from BiSH on June 2nd and on August 1st new member Ayuni D joined the group. Like all previous members, her face was obscured until she reached 10000 followers, which eventually got pushed back to 15000.

On October 8th, BiSH held the finale of their LESS THAN SEX Tour at the famous Hibiya Outdoor Concert Theatre, their largest venue yet. Two days later, their major debut album KiLLER BiSH was released.

In late November, BiSH announced that they would go on hiatus for the rest of the year while Aina The End underwent surgery for vocal polyps. They ended their activities with the free concert, iN THE END on December 5th.

2017 Edit

BiSH resumed activities in January 2017 with their sold-out BiSH NEVERMiND TOUR. All of their other concert tours for that year would also sell out.

Their second major single, Promise the Star, was released March 22nd, followed by the mini-album GiANT KiLLERS on June 28th. The album included their first promotional tie-in song, "Shakai no Rule", used as the ending theme for the anime Heybot!.

On November 4th BiSH had a surprise release of their second major album, THE GUERRiLLA BiSH. The album was released at a price of 299 yen without any prior advertising, and the surprise edition is packaged without cover art or a lyrics booklet, a reference to Kanye West's sixth album Yeezus. The album was eventually re-released with all of the missing features on the 29th that same month.

In December, BiSH, alongside other WACK groups contributed on the shuffle album WACK & SCRAMBLES WORKS.

On December 30th, it was announced that BiSH had taken the top three spots in the first WACK General Election (Cent Chihiro Chittiii at #1, Aina The End at #2 and Ayuni D at #3)

Not long after, their next promotional tie-ins, Life is beautiful / HiDE the BLUE was announced, and they released a music video for Toumeina Mama de Yuke., a song recorded to promote the Kirin Lemon soft drink.

On May 22nd, BiSH concluded their concert tour at Yokohama Arena, their largest venue to date, and where BiS had previously held their disbandment concert.

To poke fun at all of their recent promotional songs, BiSH released the single NON TiE-UP by surprise the same day Life is beautiful / HiDE the BLUE was released, in the same manner as their previous album, THE GUERRiLLA BiSH.
