Been sparring a lot against my brother who is a pretty good hazama so I'll give you my thoughts on the matchup
You really have to be patient, if you dash/jumpdash in you will most likely get chained in the face. I find out the best way to close the distance is just jumpin forward and blocking the chains. Of course if he decides to chain into you (and you manage to block it), punish it with 6a or Inferno Divider.
After you memorize his BnB blockstrings the match gets way easier. Wait for the overhead, block it and put a good ol' 5b inbetween his next hit. Enjoy the look on his face and launch his snakeass in the air.
I will guarantee that if you dashcancel your 5d's on block and continue attacking all the time, there will be a hyotenjin waiting for you. Rememeber - It's all about fishing. Bait that shit and punish it.
Dead Fang is your go-to move against hazama. If he just keeps chaining (and you keep jumping forward), wait for the right time and use it. I don't think he has any ways to punish it if you use the followup and you didnt use it in jabrange or something. If he blocks it try to mix it up with rapid cancels to throws, overheads or lows. Just don't use the deadfang>rapid>throw too often or they will expect it.
My heat gauge goes pretty much on rapid cancels everytime, just because pressure is so important against hazama. As someone said earlier, he has pretty bad wakeup options so keep the pressure up. Blockstring ending? Rapid that shit and start it again.
Right now this is my fav matchup. Intense fishing action on both sides.
