Infinite Tsukuyomi (無限月読, Mugen Tsukuyomi) is chapter 677 of the original Naruto manga.
With the dōjutsu reflected on the moon, and the Infinite Tsukuyomi initiating, Tobi abruptly ends the battle, and states that his job was done before releasing the encased Yamato stating that he also had no need for him any longer. The Allied Shinobi Forces brace themselves for another meteor impact but Naruto once again manages to deflect it. Realising the impending danger, Sasuke rushes back to his comrades as Madara casts the genjutsu over the world declaring that everything would become one. As light emanates from the moon, turning the night as bright as day, the shinobi on the battlefield, as well as all the people and animals around the world begin to fall under the genjutsu with the Rinnegan reflecting in their eyes. The reincarnatedHokage are the only ones left unaffected by this and are left powerless to do anything but watch on as Madara used the God: Nativity of a World of Trees technique to connect all living things to the holy tree's own life force. Sensing the direness of the situation, Naruto moves to help his comrades, however, Sasuke stops him telling Naruto that the only reason they too hadn't fallen prey to the technique was because he was able to use his Susanoo as a shield from the technique and if they were to leave its protection, the same fate would befall them. Just outside the protection of Susanoo, Black Zetsu watches on, wondering if Sasuke's Rinnegan was able to counter the Infinite Tsukuyomi. Meanwhile back in Konohagakure, Minato — who had flew there with Madara's Truth-Seeking Balls — looks on as the citizens are encased by the holy tree and wonders just what is happening.
When Tobi the Zetsu clone separates himself from Yamato, Hiruzen calls out his current codename; however, Hiruzen was already dead when Tsunade became Hokage and gave Yamato his new codename, making it impossible for him to have known it. However, it's possible Hiruzen learned of it the same way as he did of his son's death, through Naruto's memories.
Back in chapter #669, Minato teleported away with five of Madara's Truth-Seeking Balls. When he regains consciousness in Konohagakure, there are six spheres on his coat. This was not corrected in the tankōbon version.
