Checkicco were a Japanese idol group that was active from 1998 to 1999. It was formed by Masahiro Mizuguchi, a producer for Fuji TV who had the idea of creating "an Onyanko Club for the Heisei era". 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 just like Onyanko Club's members did.
Checkicco held their final performance in November 1999, in front of an audience of 10,000 at Tokyo Bay NK Hall. They have since reunited in 2004, 2009, and 2024.
Anime theme singer Mikuni Shimokawa and gravure idol Asami Kumakiri are two well-known former Checkicco members.
