I watched Tokyo Zombie, a 2005 zombie-martial-arts-comedy film from Japan. Shaun of The Dead meets Drunken Master I guess. The 2 main characters are workers in a fire extenguisher plant, and in their spare time one is teacing the other jujitsu. So there is a lot of jujitsu in the movie. To cut to the chase - zombies appear all over Tokyo, and our heroes decide to escape to Russia - because Russia is a manly country and they want to become real men and professional fighters. It doesn't quite work out that way... The rich survivors establish a walled society in the ruins of Tokyo and use less fortunate survivors as slave labor. (They generate electricty by making slaves squeeze those spring grip exercisers, hooked up to batteries.) The Student is now a professional fighter, but he fights zombies for the entertianment of the Rich. The movie is pretty funny, and has some good jujitsu in it.
