Toshima gun
Toshima ( Japanese 豊 島 郡 , Toshima-gun or historically Toshima no kōri ) was a district ( gun / kōri ) of the Japanese Ritsuryō province of Musashi . It existed until 1878 and was completely located in today's prefecture (-to) Tokyo .
Before the 17th century, when the Tokugawa were entrusted with the shogunate over the whole country after the final victory in the civil war ( Sekigahara ) and Edo became the seat of government, Edo also belonged to Toshima. In the Edo period, the majority of the district belonged to Shogunate and Hatamoto countries ( bakuryō ) . After the fall of the Tokugawa and the Meiji Restoration , Toshima was briefly administered from 1868 by the united Musashi governors (Musashi chikenji) , who ruled most of the former shogunate countries in the province without the Edo renamed Tokyo , then divided between several prefectures and finally came to Tokyo entirely in the first big wave of prefectural mergers in 1871. In the wake of the circles as a modern administrative unit in 1878, he was in the districts of North Toshima ( Kita-Toshima ) and South Toshima ( Minami-Toshima shared) with the district towns Shimo-Itabashi and Naito-Shinjuku.
