hey, all. for once, this isn't about my ASB ATL OR Anglo-American Rivalry; instead, it's about a fantasy story i'm writing set in feudal Japan (though it's partly AH since it has an established divergence from actual history and the first events described are historical). that's beside the point, though.

using whatever PODs and circumstances required, how long does everyone think it would take for Oda Nobunaga (and his immediate successor if necessary) to completely conquer all of OTL Japan? this means that he would have to move out of southern/central Honshu and get northern Honshu, Kyushu, Shikoku, Hokkaido, and the Ryukyus

here's a map of the period from wikipedia for reference:
