GTO (1998)

Have a similar concept, about a male protagonist that goes to school to become a teacher, though the teacher in GTO is originally a yankee..

They , both have very similar pot. And are funny in there own ways .

This drama is very similar to HAMMER SESSION since they both involve teachers, who solve the students' problems in unconventional ways.

Both have almost the same story and both have Oguri Shun.

Both these shows are about an unlikely teacher leading a group of unruly delinquent students to academic success(a High School Diploma)

Both are about teachers who really care about their students and teaches them life lessons. SCHOOL!! is like GTO only with elementary school kids.

Both are about a teacher trying to help a troublesome class to find their way.

Same type of humor. While both of the series are old, they're funny, witty and the main characters antics are quite similar as well. Both men are determined to do their jobs following their own set of rules..and end up changing the lives of those around them.

Both stories involve a homeroom teacher who finds creative and unconventional ways to fix problems in the classroom and the students' personal lives.

Both shows are mainly comedy. The style of humor is pretty similar (thirsty male characters) and the female main roles have a similar vibe. They sometimes rapidly switch from over the top comedy to seriousness without a warning.

The leads both possess a hidden personality, covering a goofy front with a passion for education. Both dramas deal with the school setting, bad teachers, bullying, and family drama. Both leads are eccentric, charismatic men with a penchant for taking unpredictable actions. If you liked GTO, I highly recommend Kazoku Game.

Both are dramas about teachers protecting students from adults and the scary world that's trying to take advantage of them.

It's also the story of how a new teacher interacts with their students and makes a change in their lives.

Both are about dedicated teachers with a unique personality. They care deeply about their students and try to help them in various ways. The episodes follow individual backgrounds of the students in his class, and deal with subjects like bullying, false accusations of sexual harrassment by a student, and family issues, etc.

different variation of the plot : "loser" students arent actually losers or delinquents and this teacher will show you how in his own special way.
