| Notes |
| Commissioned as Muikaichi Hikimi Line (General Prefectural Route) - 13 June 1958 Named route 173 - 1972 Promoted to Principal Local Road - 1 April 1976 Renamed route 42 - 11 March 1977 Route name changed to Yoshika Hikimi Line - 31 March 2006 This visit is as of yet incomplete. I was only able to travel the southernmost 11 km, as the road was closed beyond that, presumably due to winter. |
