Good, I've been meaning to shed some light on this match up too, I'll update the OP with the proper info as well.
There are two Jins to fight;
The Aggressive type
The Passive-Aggressive type
The Aggressive type of Jin is actually the easier version, he will run in with a bunch of yomi DP, jump cancel everything, tick throws, mild zoning, the works. Personally, I enjoy Jin in my face more than at a distance, his zoning game actually hurts Arakune's freedom, dealing with Hishouken, 2d and DPs can be a pain, which is the main forte of passive-aggressive types. So when he's in your face you have options.
IB everything, Jin's strings are so dima-a-dozen, it's a crime not to, react to the jumps, time your 5cs right, j.a if you're not sure, if he tries for a cross up, he loses his momentum. Watch out for EX air hishouken (j.236d), that will kill your anti-air attempts. Chose your backdashes right, most players don't do it, but some players will yomi it and punish with 6b, 2d or for those feeling themselves, ice car. Just block some things, Arakune is roughly disadvantaged here in neutral.
The Passive-Aggressive type of Jins are the more annoying ones, they have the proper tools to stay mid-fullscreen and spam Hishouken, TK Hishouken, 2d, DP on reaction, backdash any approach you do and so forth. This is a match up of patience, you simply have to out-zone Jin, get the right clouds out, time your 6ds right, turn invisible and be patient. Don't try to pursue him too much. These types will capitalize on oki above all, once they see an upper hand, they will get in there and play it safe. Once he's curse, you gotta lock him down hard, because more than likely, curse will activate fullscreen, and that's a pain in the ass.
Roughly I say the match up is even, maybe slightly in Arakune's favor, because Jin has to play a really safe game and make more crucial judgment calls than you. It's one bad guess and it's his ass (whiffed DP, bad air hishouken, bad 2d, etc).
