藩閥
Although the former daimyos had become government employees, they still retained a measure of military and fiscal independence, and enjoyed the customary veneration of their former subjects. This was considered an increasing threat to central authority by Ōkubo Toshimichi and other members of the new Meiji oligarchy, especially with the large number of ex-samurai revolts occurring around the country. In August 1871, Okubo, assisted by Saigō Takamori, Kido Takayoshi, Iwakura Tomomi and Yamagata Aritomo forced through an Imperial Edict which reorganized the 261 surviving ex-feudal domains into three urban prefectures ("fu") and 302 prefectures ("ken"). The number was then reduced through consolidation the following year to three urban prefectures and 72 prefectures, and later to the present three urban prefectures and 44 prefectures by 1888.
