Prefectural roads (都道府県道 , todōfukendō , singular depending on the type of prefecture: "todō", "dōdō", "fudō" or "kendō") in Japan are roads usually planned, numbered and maintained by the government of the respective prefecture (-to, -dō, -fu or -ken), independent of other prefectures – as opposed to national roads (kokudō), which in legal terms include national expressways (kōsoku jidōsha kokudō), and municipal roads ([ku]shichōsondō).
 Where a national or prefectural road runs through the territory of a designated major city, the city government assumes part of the responsibility for these roads.
 By length, 10.7 % of public roads in Japan were prefectural roads as of 2011; by usage, they carried more than 30% of all traffic volume on public roads as of 2007.
