"The Day Naruto Was Born" (ナルトが生まれた日, Naruto ga Umareta Hi) is episode 380 of the Naruto: Shippūden anime.
Yin-Kurama asks Minato whether he intends to let Naruto clean up after him, noting that him becoming a jinchūriki wasn't so bad. Tobirama thinks Naruto resembles Hashirama in his ability to work with the Flying Thunder God Technique and use of Senjutsu. Obito makes notice of his new vulnerability and creates a giant flowering tree. Each of the four flowers begins charging a Tailed Beast Ball. The Allied Shinobi wonder how they can escape those, and Minato and Tobirama each able to teleport only one of them away. Hashirama wants to help them, but is impeded by Madara, who reminds him that their reincarnated bodies will regenerate. Obito sends out chakra receivers and erects a barrier trapping the Alliance with the tree. Naruto fist-bumps with Minato for a new strategy, connecting both halves of Kurama. Obito wraps himself in a protective cloak, still berating Minato, reminding him that it's his and Kushina's death anniversary the next day. Naruto instead remembers it's his birthday. Minato marvels at his grown-up son. Minato and Naruto meld their halves of Kurama's chakra, and the cloak on the Alliance shinobi reappears. Jūgo arrives at their location and tells Sasuke they need to escape via reverse summon. Naruto shares his chakra with them as well. Obito fires the Tailed Beast Balls. The Alliance appears unharmed, having been teleported out of the barrier by Minato, by proxy of Naruto's chakra. Tobirama notes the similarity with the Shadow Clone Technique regarding to chakra distribution, impressing Naruto with the knowledge of the technique, revealing himself as its creator. Minato wishes to talk to Naruto, but Naruto says it's not necessary, having already met his mother's chakra.
There is an animation error in which Sasuke's Mangekyō Sharingan displays Madara's pattern instead of his own.
