Are the martial art techniques in Kenichi real? I've been wondering for a while are all the martial arts and martial art techniques in this series real? I used to be a former karate student, so I do know that the karate techniques used in the beginning 200~ chapters are legit. 

As the series progressed, however, the karate techniques started to become a lot more complex and I have never even heard of them before.

Then they also started deviating from the standard martial arts and introduced some like pencak silat (which I never knew existed before).

If there are some fake styles or techniques, which ones are there*? 

*Please don't use unreal fights to disprove. For example, when Akisame fought against that other master and they proceeded to counter-throw each others counter-throw, ultimately leaving them suspended in midair for half the chapter. The technique of a counter throw is real, but the manga just used it unrealistically.
Check this for a list of the martial arts used in Kenichi.

Some of the martial arts are of course just fictional or adapted, like Nyakwondo (a combination of cat moves and Tae Kwon Do) and even Furinji's own style. However, majority of the martial arts in the manga/anime is still legitimate and--based on personal experience as a former wrestling competitor in university days--relatively accurate.

Also, I won't rightly consider "fake" some of the variations, as martial arts in real life are mostly just variation of one another. Kung Fu alone is credited for inspiring at least a couple of major styles, and die-hard practitioners and fans alike will call fake on these other inspired arts. However, I must admit that Kenichi deserves an amazing suspension of disbelief with some of them.

Also, a bit out-of-topic:


   I personally find it amusing that you're a karate practitioner and you don't know prior to Kenichi about Pencak Silat when it's one of the most murderous martial arts in the world. While most martial arts are developed in defense, the likes of Muay Thai, Muay Boran, and Pencak Silat are meant to utterly disable, maim, and outright kill opponents.

 Granted, Silat is a huge discipline, but the Pencak variant is the recognized national martial art of Indonesia and it's been shown to be highly effective (a movie even had tons of people using it, including the "regular" street mook), not to mention Hayato Furinji himself had some issues with the art's complexity.
