Hokkaidō Prefecture, however, came much later to the ritsuryō provincial system, only a few years before the prefectural system was introduced, so its eleven provinces included several districts with the same names: Three Kamikawa Districts and two Nakagawa Districts in the Hokkaidō Prefecture.
Prefektur Hokkaidō lahir jauh setelah sistem provinsi ritsuryō berlaku, dan berjarak hanya beberapa tahun dengan penerapan sistem prefektur terbaru, sehingga terdapat 11 provinsi termasuk beberapa distrik yang bernama serupa: Tiga Distrik Kamikawa dan dua Distrik Nakagawa di Prefektur Hokkaidō.
