Why do you think Inuyasha does not get jealous about Hojo Akitoki, but he does about Koga?

Here is wat I think.
Koga: kicks butt, hot, full demon, not afraid to tell his feelings, and lastly Totally FLIRTY!
hojo: whimpy, scaredy cat, can't fight, bad with words, not really a flirty, and he could never win over kagome!
That's why koga is more of a threat.

Inuyasha doesn't even know about Hojo, other wise he'd be all up in his face to, just like he is with Koga.

Oh wait which Hojo are you talking about, past or future Hojo? I know he isn't aware of the future Hojo, but no he doesn't seem to care much about the past Hojo (from the Movie 2 and 2 filler eps), probably because he isn't really cannon so why should he even care, not like the guy's a threat anyway, X3

I think because Koga can kick butt!
But Hojo Akitoki???
I think Inuyasha thinks that Koga can protect Kagome thats why he is a mjojor threat to him!!

b cuz inuyasha didnt know him... i think

My answer is because:
Koga is kinda cute.
Hojo Akitoki isn't that cute.
Koga is strong.
Hojo Akitoki is weak.
Koga can protect Kagome.
Akitoki just can't.
Koga isn't afraid to admit his feelings for Kagome to Kagome's face.
Akitoki is afraid to admit his true feelings for her to her face.

And that's my conclusion of why InuYasha doesn't bother with getting jealous over Akitoki talking to Kagome,but gets jealous over Koga coming and trying to talk to Kagome.

I hope that my answer was good enough.

Oh yeah,I almost forgot to mention that Koga is the one that told Kagome that he loved her.

Nope. he did angry but then, Hojo ancestor, No. When there were cultural festival, Kagome was doing a Theater play, when Hojo hold her hands, inuyasha came out from no where and were angry. Cuz he was touching kagome. While hojo acestor. AKi hojo, i think Inuyasha was too confident with himself, and know that there's no way kagome will fall for a weak, bad luck and always run away like tht. so, yeah ;P

because he know hojo is a goof and kagome would never go with him. and koga on the other hand kagome could run away with him cause he is strong handsome and inuyasha feels koga will kidnap kagome again!!

I am almost done with the show and so far, Inuyasha has never actually met Hojo. In one episode he interacts with Hojo at the cultural festival, but it was only during a play when demons were attacking and stuff... so he isn't jealous of Hojo because he has no idea that Hojo exsists.

Simple Akitoki Hojois a wimp nothing more like a cry baby and he give weird tips to on health and other things!
Now Koga: he's hot, cool, leader of the wolf demon tribe, and cares more about kagome's feelings that why Inuyasha is so jealous of Koga!!

Because Hojo, bless his soul, is weak and Koga actually poses a challenge to Inu

because Inuyasha has a few feelings for Kagome, because Kagome is the reincarnation or Kikyo.

My theory is because Inuyasha doesn't even know Hojo. I mean, of all the times he ventured into the human world never did he run into Hojo or neither did Kagome mention his name.

I guess its like a dog instinct, Inuyasha likes Kagome, and Koga keeps trying to take her. No one else does this but Koga.

It's obvious why. Koga has more of a shot with Kagome than Akitoki does. But anyway, even though he didn't show it, Inuyasha was TOTALLY JEALOUS!

Correct me if I'm wrong, but I personally think it's because Kagome never told Inuyasha about Hojo, (or at least according to the manga and the anime) therefore it would be pretty strange and/or creepy if Inuyasha were to stalk her. He has done 'similar' things but those were only for good intentions and not creepy love-struck obsessive ones. So it's almost ninety nine point nine percent impossible to be jealous of a guy's affections for someone you never heard about. He did meet Hojo on some occasions like the play and the ancestor of Hojo, but Inuyasha never knew that another guy, ( Except Koga) had a romantic crush towards Kagome. Hojo is more sweet than Koga for Kogo can be pushy and straight-forward while Hojo is willing to wait for Kagome to reciprocate his feelings if she isn't ready. But anyway that's my answer. Better get back to watching Inuyasha. Can't liv without my dog boy XD
