Watarirouka Hashiritai 7

History

In October 2008, Yasushi Akimoto announced that he was going to revive the 1980s girl group Ushirogami Hikaretai, using four members of AKB48 and was renaming the group to Watarirouka Hashiritai. The group debuted under Pony Canyon releasing a double A-side single, "Hatsukoi Dash/Aoi Mirai" on January 28, 2009. The single entered the Oricon single chart at number ten. On April 22, the group released their second single, "Yaruki Hanabi" which charted at number nine.

On November 11, 2009, the group released their third single "Kanpeki Gū no ne" which was used as the first ending theme song for the anime version of the manga Fairy Tail. This single had more success than the other two singles, as it sold over 23,200 copies in its first week and charted at number seven. In February 2010, Ayaka Kikuchi joined the group changing the roster from four members to five.

Their first single in 2010, "AkKanbe Bashi," became the first single from any AKB48 sub-unit to reach number 1 on the Oricon charts.

On June 30, 2010, two members from AKB48, Misaki Iwasa and Mika Komori, were added to Watarirouka Hashiritai to form "Watarirouka Hashiritai7", but the name applied to their "radio-only" activities, as two singles and an album released on and after June 30 were under the name of "Watarirouka Hashiritai", not as "7" since the two newcomers were not included. They eventually debuted as "7" with their seventh single "Valentine Kiss", a cover version of Sayuri Kokushō's single, originally written by Yasushi Akimoto and released 25 years earlier.

In mid-2011, Hirajima announced on the group's official blog that a new single would be released by the group on August 3 of that year. Kikuchi revealed on July 4, 2011, that the title of the song would be "Hetappi Wink". Both Hirajima and Kikuchi described it as "a summer-ish, energetic and bright song". This was the second time a single was released with the "7" in the group's name.

On June 25, 2012, Watarirouka Hashiritai 7 took part in Yubi Matsuri, an idol festival produced by Rino Sashihara from AKB48. The concert was held at Nippon Budokan before a crowd of 8,000 people and featured such girl groups as Idoling!!!, Shiritsu Ebisu Chugaku, Super Girls, Tokyo Girls' Style, Nogizaka46, Passpo, Buono!, and Momoiro Clover Z.

On August 24, 2012, during the AKB48 in TOKYO DOME 1830m no Yume concert tour, it was announced that Aika Ota and Haruka Nakagawa were transferred to HKT48 and JKT48 respectively.

On November 13, 2013, it was revealed that the group would disband on Christmas and at the same time, release their first (and only) best-of album, titled "Watarirouka wo Yukkuri Arukitai".

On February 9, 2014, their final concert was held at ZeppDiver City, Tokyo.
