Majisuka All-Girls' Private High School (私立馬路須加女学園高等学校, Shiritsu Majisuka Jyogakuen Koutou Gakkou?), also known as Majijo (マジジョ?), was a yankee (delinquent) school that was the main setting for most of the Majisuka Gakuen series. It was established on 1975. Before the events of the Majisuka Gakuen, it was later turned into a Private School for girls up until the arrest of Maeda Atsuko, where it underwent a period where it was changed from a private school back to a public school. It was already known as Majisuka Jyogakuen Koutou Gakkou (馬路須加女学園高等学校 Majisuka All-Girls' Senior High School?) during the events of the Majisuka Gakuen Stage and Majisuka Gakuen 4. It is unknown if there is a connection between the school and Prison HOPE, which is also called "Majisuka Prison" (マジすかプリズン?). During the events in Majisuka Gakuen 5 the school was under threat of being shut down due to numerous deaths of it's students and alumni involving multiple syndicate groups, particularly by Akechi Sougyou.
In Hatsumori Bemars, Imadoki mentioned that she beat up Majijo students before arriving at Nanamaru's Monja House. This made Imadoki known as someone who is in even terms with Majijo's students, which also brought the attention of other Yankee Girls' Groups. Before their team's first softball battle, Kachidoki called out for Imadoki in fighting two Yankee students who heard of Imadoki's feat against Majijo's students. Other Female Yankee Groups such as the Kurobara Girls' School's Yankee Musume also targeted Imadoki's former crew so they can fight her.
- Because of the transfer from TV Tokyo to Nippon TV, some characters were re-casted. Their background seems like it was also changed as some of their personalities from the previous series differed.
- Team Hormone's leader Wota, renamed Scandal, was a held-back 3rd year student at the new version of Majisuka Jyogakuen.
- Majijo graduate Torigoya became a model-idol and became known as Kojiharu, shown to have a completely different fighting style, which may have meant that Torigoya became stronger to the point where she doesn't need to use her powers, or may perhaps have gained the ability to use her powers without touching her targets first.
- Almost all students of Majijo to date were portrayed by members of AKB48, including members who have transferred or had concurrent statuses. The only exceptions would be:
