"The Secret of the Space–Time Ninjutsu" (時空間忍術の秘密, Jikūkan Ninjutsu no Himitsu) is episode 342 of the Naruto: Shippūden anime.


Naruto's attack is countered by Tobi who declares that no one shall hinder the statue. The group then prepares to go all-out. Easily gaining the upper hand against Naruto, Tobi has a harder time as Guy, who took out a pair of nunchaku, joins the fray. Amidst the clash, Guy is able to create an opening for Naruto to land his attack. As Tobi is distracted, Kakashi uses Kamui and aims for the Demonic Statue; however it nullified the attack, much to his confusion. As Naruto fails to land his attack, he is separated from the others and now has a harder time holding his own against Tobi. Rushing to Naruto's aid, Kakashi launches his lightning-imbued kunai at Tobi, however the latter changes its trajectory at Naruto instead. Kakashi uses Kamui in time to warp it. Just as the group exclaim Tobi is too strong, a slight fissure appears on his mask. Frustrated, Tobi erects a barrier around the Demonic Statue, preventing B from landing a fatal blow. Analysing the masked man's abilities, Kakashi asks the group to aid him in testing his theory. After putting the plan in motion, Kakashi realises that Tobi is only using a single technique. Having explained Tobi's abilities to the group, Kakashi reveals that their techniques lead to the same dimension. Kakashi asks Tobi where he got the Sharingan from, to which the latter tells him that he got it from the battle at the Kannabi Bridge, much to Kakashi's disbelief. As Tobi states there is no more hope for the world, Naruto rejects his views and Kurama — who switched with its jinchūriki — declares that the Fourth Hokage sealed it inside Naruto to take him down. With that, the Nine-Tails commands Naruto to charge. Now wearing a new version of the form, Naruto then charges forward, ready to take Tobi down once and for all.
