Idol Kyoushitsu

Idol Kyoushitsu (アイドル教室), also known as Idol Class, was an idol group based out of the sushi restaurant GOICHI located in Nagoya, Aichi. The restaurant owner, Umemura Noriyuki, was the group's producer since their formation. The group and individual members regularly perform at the restaurant.

The original lineup (the 1st Generation) changed their name to Idol School and continued to perform, while Idol Kyoushitsu was dormant until the addition of the 2nd Generation in November 2009. While still called the group's 1st Generation, these members are not typically listed as former Idol Kyoushitsu members and the formation of the group as it is known now is considered to be its November 2009 revival.

Idol Kyoushitsu is the flagship group of the AiKyou agency, which contained four sister groups over its history: Happy & Happy, Sentimental Lover, AiKyou Jr, and AiKyou Turbo. The agency's trainee group, Sushidol Jr, promotes into all groups, and the generations of trainees are based on Idol Kyoushitsu generations beginning with their formation.

On August 6, 2022, it was announced on their official blog that the group would disband on December 31, 2022 following the sudden passing of their producer on April 23, 2022.
