Basically it confirms what nja said, says the Yondaime Mizukage's name is Yagura (one Japanese commenter wonders if he's also the Sanbi jinchuuriki since that's supposed to be his name) , says the Sanbi jinchuuriki (they used incorrect spelling/kanji here) had some marking starting from underneath his left eye to his cheek, talks about a picture shown of a former Kazekage (presumably Gaara's dad), and that a Sai/Sakura talk happens after the Kage part (insert rolling eyes here). Sai talks about how he doesn't know what type of promise Naruto made to Sakura, but that she should already know how much he likes her. To which Sakura replies when she thinks about it she bursts out and cries. Sai says some more stuff designed to make Sakura think about it.
Anyway I'm not posting this in the spoiler thread, nor do I want it posted there since it's best to wait for Ohana, but just wanted to let you guys know what was going on in the Japanese board.
