User blog comment:Sainami/Ame's Evolution – Jinchuuriki and Tailed Beasts/@comment-951734-20140112214306/@comment-5963425-20140115180659

The following villages have a beast in their possession:
 * Kumogakure - Hachibi
 * Sunagakure - Ichibi
 * Kirigakure - Rokubi
 * Takigakure - Nanabi
 * Iwagakure - Gobi
 * Getsugakure - Sanbi
 * Kyuubi's host has no affiliation to a village but is loyal to Tengu.

See the villages blog who else is still able to have a beast in their arsenal. Do ask the Kage/Daimyou if you can make your host from their village.
