Han (ハン) was a shinobi from Iwagakure and was the host of the Five-Tailed Beast, as well as the physically largest jinchuuriki, easily standing a head taller than Kirabii. The Five-Tails has been captured and sealed by Akatsuki, causing this jinchuuriki's death when the beast was extracted. Another jinchuuriki, named Roushi, who held the Four-Tailed Beast, also originated from Iwagakure. It is logical to assume that he and Roushi knew each other as they were both jinchuuriki of the same village.
