I can’t confirm the translation of the summary of the video, so if you don’t believe this one, go to the website, and find your own translator.
1.When Kishimoto first created Naruto he was inspired by a roadside ramen stall, he wanted to write about a youth eating ramen. his theme is considered questionable, bujt in the end it still became serialized while under doubts.
2.The fourth’s appearance was inspired by carelessly jumbling up kiba and akamaru’s combination. and so naruto father’s image was set.
3.Before the chunnin exams, Kishimoto originally wanted to draw a few more missions, but to ask him to illustrate the whole ninjaverse at one go, kishi says it is very stressful to have to do so many characters, so he asked his assistant for help, and the assistant created Lee using reference from Jackie Chan.
4.In Akatsuki Kishimoto’s fav is Hidan. Kishi was told that the image of Shikamaru smoking can’t possible be animated on TV, but Kishi did it anyway. He tried to make Hidan look not as intidimating
5.Kishi feel that Jiraiya’s death was spectacular, therefore if he was edo tensei, it would be hard to draw naruto’s reaction. that’s why jiraiya did not re-appear.
6.Kishi is troubled by Sakura’s popularity among the readers. While he was drawing covers, it was easy drawing naruto and sasuke, but for sakura kishi have to spend more time re-drawing and adjusting, worrying that he might draw her ugly. sakura’s family is not revealed because of popularity reasons, but hinata with low number of appearances were consistently popular with the readers, kishi once had the idea to change hinata to the heroine.
7.he let neji die for naruto and hinata to be closer, that’s how hinata brought her daughter to visit his grave in chapter 700. naruto’s son boruto and neji is the same meaning, this is all intended early on.
8. before naruto KO enemies kishi would use several different angle shots to show the same move, this is inspired by jackie chan’s martial arts film. also when doing KO scenes kishi don’t like to draw the character faces, he feel that revealing faces will dimish the impact of the body moving and the artwork.
9.At the end when Naruto and Sasuke fight, the original intention is that they finish while holding hands, but kishi changed his mind and cut their hands, making a more gory ending.
10.When NARUTO ends, Kishi introduces next year’s movie and naruto exibition 2015, revealing that orochimaru, kabuto, and lesser characters will be re-appearing in the boruto series, to finish the main plot. then kishi says he will be relaxing for the time bring, call an assistant to discuss about the new series. it is unclear whether the new series will still be centered around ninjas or around a totally new theme.
EDIT: A translator i trust, also said Kishi said this:
1)Kakashi got more popular than Naruto so he had to decrease his appearance
2)This 15 years he suffered because of Sasuke and Sakura
3)To make Hinata look more like Naruto’s heroine, Neji had to die like a cupid (to which the interviewer caution, can we air this??)
Persona 5 hype 
They still like NaruHina though, but I know all of us NaruSaku fans are not delusional for believing in our ship! It was blatantly there.
