Like all fandoms, there are divisions in the japanese fandom. What I am about to post are from conversations I had with fellow Japanese fans around Sakura's Confession, who do not identify as NaruSaku fans. Actually, one of them is a NaruHina fan. I am posting here because there are some good debate topics. I also added things I found on Japanese blogs.
Sakura's Confession Conversation
- point in the story where both Sakura and Naruto do not fully understand each other's feelings. On one side, Sakura believes she is the reason (the promise) of Naruto's suffering over Sasuke. At this point she did not think that Naruto had other reasons besides from her promise and this is widely agreed that Sakura had a misunderstanding of Naruto's feelings. For Naruto, he knows that Sakura is withholding something and is lying, but he does not understand why. He sees the lie because he can see into people's hearts.
- everyone agrees Sakura was indeed lying. indication is that she could not look at Naruto in the eye and her eyes went to the left, which means she is lying (eye aversion ->lying. to me, I don't really believe in the whole left/right eye movement).
- someone brought up that it's possible that she misunderstood him on purpose so that Naruto can hate her.
- a stark contrast of Sakura's hugs to Naruto (first after the Pein arc)
The Hug Part
- Atmosphere important
- After the Pein War hug, the hug is considered the "warm" hug because of the warm atmosphere (end of the war, cheering, etc)
- Confession hug, it is snowing and the hug is considered the "cold" hug. Sakura hugs Naruto so that she does not have to look into his eyes. Knowing she is going to do something unforgivable.
- white snow -> Sakura's "white" lie
- Sakura has to realize her "warmth" comes from Naruto.
What was Sakura lying about/true feelings?
- this part is is pretty tricky. she is lying because she is trying to mislead Naruto from what she is about to do (take down Sasuke) but is she lying about her feelings for Naruto? It is not so easy for anyone to say yes or no. She says them to relieve Naruto from his suffering, is that enough to show that she is affected my Naruto? Sakura is beginning to realize romantic feelings for Naruto.
- she is saying things she subconsciously knows.
- Is Sakura still in love with Sasuke? Mostly no.
A Scrutiny on Kiba's Appearance (469) O_O??
- This part actually really surprised me because I never even thought of it, but it was brought up like 4-5 times. Kiba seems to understand the feelings in the situation?
Thanks for sharing this with us. I like that bit about the "warm" hug in 450, and that Sakura has to realise her "warmth" comes from Naruto. I've heard that whole "Sakura didn't understand Naruto, she thought he was only chasing after Sasuke because of her" and I gotta say that I wholeheartedly disagree. She clearly knew how Naruto felt about Sasuke—she's a smart, reasonable girl. Of course she wouldn't think that. Besides, she explained to Sai at the Tenchi Bridge that Naruto viewed Sasuke as a brother, and she was there when Shizune said to Sai that Naruto wanted to bring back Sasuke for himself, too, not just for Sakura (and Sai agreed). And after Sakura's confession, Sai explained that Sakura knew how Naruto would react to her request for him to stop chasing Sasuke.
About Kiba—yeah, I've heard this before, too. That Kiba's reaction to Sakura's confession means that he knew she was lying. No, it was obvious he was mad because she was supposed to be telling Naruto about the Rookies' decision to off Sasuke, but she wasn't doing that at all.
Well I can elaborate some more, but I do want to say that in my opinion, most believe that Kishi will end with Naruto and Sakura as the romantic couple, but it does not mean they are only NaruSaku fans, there are plenty of SasuSaku, NaruHina, etc just like all other fandoms. I also
"Is Sakura still in love with Sasuke? Mostly no."
What I'm going to post is from conversations with a NaruSaku fan, a NaruHina fan, and the others didn't identify themselves are any pairing fan.
- What is brought up many times is the quote along the line of "A woman's heart changes like the autumn sky". Taking into consideration Tsunade's and Kushina's hearts. Tsunade had come to love Jiraiya when at first she did not, Kushina's heart changes too for Minato. Slowly unknown to herself, Naruto has become close to Sakura's heart and is truly an important person to her. That is why she lies (because she realizes Naruto is an important person. don't you lie to people you are close to sometimes?).
- I want to say that this quote is not taken as a bad connotation for women (such as their hearts are fickle). They are just saying that a woman's heart is complicated haha.
- don't believe that Sakura's love for Sasuke is "love", but a longing for the childhood love she dreamed of (does that make sense?)
- Sakura's love for Sasuke has been fragmented, held together by a childhood dream. Some say they understand it as Sakura trying to hold on to her childhood in time of peace.
*I'm not saying this is everyone's opinion, just the people whom I talk to.
NaruHina or SasuSaku moments?
- the NaruHina fan brings up the point that Hinata's confession and Sakura's confession are very different (and are actually pretty close to each other) for a reason. What is the reason? Unfortunately I forgot what he said hahaha but I don't really think there was elaboration.
- Sakura's confession to Sasuke (part one) was from the heart, something that was done out of the desperation to reach Sasuke emotionally. Sakura's confession to Naruto was done to ease his suffering.
Not really my thing to go into other pairing fandoms, but I happened to see a NaruHina fan and art club and visited. I'll put the opinions that I saw
- know that Hinata is not a main character but a sub character, the battle is between whether Naruto will be paired up with the main character (sakura) or with a sub character (hinata).
- 615 big moment - does this mean that Hinata is now a main character?
As for other moments, I didn't actively look for any opinions or in-depth analysis. I did see a couple of people note that NaruHina took a really big hit during 631, but besides that, I don't really see anybody bring it up. That is of course taking into consideration that I wasn't looking for it ^^. I'm sure there are other opinions about it though. I hope that clears up things.
Nice. I like this part in particular:
- What is brought up many times is the quote along the line of "A woman's heart changes like the autumn sky". Taking into consideration Tsunade's and Kushina's hearts. Tsunade had come to love Jiraiya when at first she did not, Kushina's heart changes too for Minato. Slowly unknown to herself, Naruto has become close to Sakura's heart and is truly an important person to her. That is why she lies (because she realizes Naruto is an important person. don't you lie to people you are close to sometimes?).
- I want to say that this quote is not taken as a bad connotation for women (such as their hearts are fickle). They are just saying that a woman's heart is complicated haha.
I've seen too many people take that "A woman's heart changes like the autumn sky" too literally, because in one of the translations of chapter 469, it was translated as "A woman's heart is fickle," as if the original quote is supposed to have negative connotations. They say that loving Naruto now would make her fickle (it wouldn't, cause she's already shown plenty of reasons to believe she has feelings for him).
Even the Anti-NS FC at Narutoforums is called "Fickle as the Autumn Skies." Please. Yeah, the point of that quote is to say that a woman's heart is complicated.
Yes it's true SasuSaku is really huge in Japan. There are so many pairing favorites in the series. What I was trying to say is that they ship any pair they want, but they mostly agree NaruSaku is Kishi's endgame.
The thing about SasuSaku is that they do not have anything to grab a hold on to, and in my opinion, they know that. I tried to balance some arguments and find some from a SasuSaku standpoint that had some ground, but it was never brought up. They just like the pairing ^^
Is NS set in stone? Most people I've come across believe that the romantic route is definitely towards Naruto and Sakura. However, they expect more development, especially on Sakura's side.
What is really interesting that I've seen a couple of times is that people are waiting for Sakura to confess another time. It was brought up that she could not reach Sasuke through her heart. They anticipate that Sakura will try again to reveal her feelings to Naruto, and that they hope Naruto will listen.
Is NH possible? Now, I would like to say yes, because I see the argument that NH had a lot of momentum in 615. The question is "Will Hinata become a main character to Naruto?" If Hinata is developed that way, NH is possible. The problem is Hinata has not taken that role. Sakura seized it in 631.
Which is why the part about Sakura's confession is analyzed - Sakura is the closest to Naruto, she understands him, as seen throughout the series and also in 631. However, Sakura missed Naruto's feelings during her confession. That is why the Japanese anticipate that Sakura confesses again.
Thanks for sharing all this with us!
It's very interesting and enlightening, especially considering this is Kishimoto's intended audience. They'd be the ones who understand his intentions the most.
You said that the Japanese fandom ship what they want, but most people agree that NaruSaku is endgame, which is actually what I thought. Nice to know they agree with us on so much. 
However, Sakura missed Naruto's feelings during her confession. That is why the Japanese anticipate that Sakura confesses again.
This part confused me a little bit, though. By "missed," do you mean she didn't understand his feelings? Or that she wasn't able to get through to him, so she'll confess again and this time she'll get through to him, get him to believe her? Or something else? Sorry, I didn't understand.
