That is not the only thing, Netero's 100- Type buddha technique influenced Hashirama's Buddha statue technique.
The chuunin exams are a rip off the hunter exams, even by the team, written evaluation and quests they have to complete to become a hunter/chuunin.
Killua lighting affinity influence Sasuke's lightning affinity.
Killua's Godspeed form is a carbon copy of the Raikage's lighting armor.
The Phantom troupe is basically the Akatsuki organization.
Hisoka and Orochimaru are extremely similar, that is why I like those two characters.
Netero being the director of the Hunter association is basically Hiruzen being the Hokage of part one.
Killua and Illumi's relationship is like Sasuke's and Itachi's relationship in part one. Illumi plays with killua's emotions and makes him hate Illumi.
The list goes on an on. You just dont want to see it lol
Kishi admits being influenced by his mentor, which happens to be Togashi the creator of Hunter x Hunter.
1. Actually, Naruto abilities are based off of Japanese mysticism and buddism (6 paths. Someone made a thread about this). The true thousand hands statue is based off of something from buddism.

2.Well, one part is similar. That's pretty much the extent of it.
3. .........:| And they don't use it in a similar way at all. Weak.
4. Yeah, this much, I noticed.
5. (insert laughing gif here) You've got a few screw loose if you think they're anything alike. Phantom troop=gang. Akatsuki= pawns of an evil mastermind looking to complete a plan.
6. Yeah, um, tell me when you find Hisoka acting like a mad scientist searching to obtain all there is. Hisoka=psychopathic killer that strengthens people in order to kill him. Orochimaru=mad scientist searching for all that is and strengthens people as a mere experiment.
7. Gee, guess Head Captain Yamamoto from Bleach is a rip-off to. (facepalm)
8. Maybe you got too far for me to catch up, but from what I remember, Illumi just wanted to make Killula the ultimate assasin, and Killula just resists him. Itachi on the other hand, is nothing like that. Their relationship is completely different.
Given your list as it is, anything you'll bring up is very shallow. It takes more than a similarity to make something a rip-off. It needs to be a copy, and like it or not, there's virtually nothing in Naruto that's a copy. There might be some inspirations, but Kishimoto obviously made his own thing. Please explain the following.
Lee and Guy including the 8 gates. (you'll probably use that kid that Gon and Killula trained in nen with, but no. Lee's all about no talent, that kid was talented. Lee is about self-rule, saw nothing about that kid)
The Hyuga clan.
Sound 4.
Tsunade (do not bring up Bisky. No similarities in personality or abilities. Just that they're both blond and have a hidden...... unpleasant form.)
Any individual Akatsuki member
Pain
Madara and Obito
Naruto conquering hatred (which few, if any shonen characters intentionally struggle with)
Naruto having to fight Sasuke, his best friend
Ohnoiki
Zabuza and Haku
The Naruto manga is independent of your precious hunter x hunter. Most similarities are shallow, and if there are any, go in a completely different direction, which makes it original in its own right. Naruto's great because of its own ideas, not those from other mangas.
