Otokojuku is a school which was established over 300 years ago which is currently administrated by Edajima Heihachi.



Otokojuku's harsh training methods stemmed from the Special Course at the Etajima Naval Academy. It is likely that while Otokojuku did exist for over 300 years ago, it was known under a different name, such as in the aforementioned Special Course of Etajima Naval Academy.

Campus Grounds

The main school building of Otokojuku is a 2-story tall archaic Japanese style school that has Sakura trees growing on campus. Aside from this, there are also the dorm rooms where the 1st-year students stay when not in class, as well as other locations, such as the Tendo Shrine, where the 3rd-year students all reside.

Dress Code

All students are required to wear the school uniform, which is your typical Japanese school uniform, as well as fundoshis as undergarments, but aside from this, the dress code is relatively relaxed, as students are allowed to style their hair in whatever fashion they choose, as well as being able to wear whatever accessory they please on school grounds, such as Momotaro's headband.


Aside from typical school subjects, such as math and English, Otokojuku is known for it's iconic grueling training methods, known as specialties that always involve the students undergoing herculean tasks that all vary in intensity to help them become men among men.
