Sushidol Jr

 (寿司ドルJr) is the trainee idol group for Idol Kyoushitsu and all sister groups under AiKyou agency. They were originally formed with the members of Idol Kyoushitsu's 7th Generation on May 3, 2014.

The member generations follow the chronology of what used to be Idol Kyoushitsu's generations, and use the term Kisei (期生; e.g. 17期生) in Japanese. The generations of Sushidol Jr as a group, however, are used to count each separate lineup, and use the term Daime (代目; e.g. 10代目寿司ドルJr). Unlike most idol trainee groups, Sushidol Jr only contains one generation of members at a time. Eventually all members are promoted to other groups, and the group stops activities for a time until a new generation begins.

2nd Generation Sushidol Jr began with the addition of the 8th Generation on May 3, 2015. It ended on August 30, 2015.

3rd Generation Sushidol Jr began with the addition of the 9th Generation on May 15, 2016. It ended on January 1, 2017.

4th Generation Sushidol Jr began with the addition of the 10th Generation on December 30, 2016. It ended on May 26, 2017.

5th Generation Sushidol Jr began with the addition of the 11th Generation on August 12, 2017. It ended on October 29, 2017.

6th Generation Sushidol Jr began with the addition of the 12th Generation on February 11, 2018. It ended in May 2018.

7th Generation Sushidol Jr began with the addition of the 13th Generation on August 18, 2018. It ended on November 4, 2018.

8th Generation Sushidol Jr began with the addition of the 14th Generation on May 4, 2019. It ended on August 17, 2019.

The 15th Generation did not form Sushidol Jr due to it only containing one member.

9th Generation Sushidol Jr began with the addition of the 16th Generation on August 2, 2020. It ended on May 1, 2021.

10th Generation Sushidol Jr began with the addition of the 17th Generation on August 8, 2021. It ended on July 16, 2022. This will likely be the last generation due to AiKyou agency's dissolution.
