Checkicco (チェキッ娘 Chekikko?) was an idol group formed by Yasushi Akimoto, who was also the producer of the group (he also produced Onyanko Club and is now producing AKB48), along with Masahiro Mizuguchi, a producer for Fuji TV who had the idea of creating "an Onyanko Club for the Heisei era (1989-present)". They debuted in 1998 with the single "Dakishimete". Their name comes from the phrase "Check it!", a catchphrase of Tomoe Shinohara.

There were several things about Checkicco that were similar to Onyanko Club. Like Onyanko Club, Checkicco also hosted their own TV show, called DAIBAtteki!. Each member also had her own number (ID) just like Onyanko Club's members did.

Checkicco broke up on November 3, 1999. At the Girl Pop Factory 2004 event, however, the members performed together as Checkicco again for only one day.

Anime theme singer Mikuni Shimokawa and gravure idol Asami Kumakiri are two well-known former Checkicco members.


Checkicco has released six singles, two albums (counting their best-of album), a small number of IVs, a photobook, and a Dreamcast game. They had several subgroups such as chee's, METAMO, and M@M, however, they were not very successful (their highest selling single, "Hajimari", only sold 32,450 copies with its highest rank as 40 — this was back in the days when best-selling CDs were the ones that sold over 100,000 copies).
