Minato developed a seal, based upon the Uzumaki ones, that could theoretically make ANYONE a perfect jinchuriki. It's a seal with greater strength and control than any other design we've seen in the series, and it's leakage allows any jinchuriki to slowly adjust to the Biju's power, rather than the all-or-nothing approach every other Jinchuriki had. Mr. Grave wrote: Maybe they sensed the destruction of Uzushio was near. Who knows. Konoha was basically entrusting them with a nuclear weapon and the possibility to study and understand it to a greater extent than anyone had before. In exchange, Konoha got the safest possible jail for a nuclear weapon.
