 If you liked
Gokusen

 ...then you might like
Bamboo Blade

They're similar because they're a group of high schoolers under one teacher and usually fight in groups; Bamboo Blade portrays "official" fights.
Bamboo Blade has less romance in it but more comedy. If you liked Fuji (the dog) in Gokusen or the Yakuza crying when acting like in a theatre play, you'd probably like Bamboo Blade for similar reasons.
If you liked Gokusen for the martial scenes, Bamboo Blade is also a good choice. They really show appreciation for kendo and the technical side of it, while also having females practicing and being great at it.
