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.
