History

  • 1897: Hiyama Subprefecture was established.
  • 2005: Kumaishi Town (Nishi District) was merged with Yakumo Town (Yamakoshi District, Oshima Subprefecture) and transferred to Oshima Subprefecture. At the same time, Hiyama Subprefecture was divided between north and south.
  • 2014: Esashi Line (from Kikonai Station to Esashi Station) was abolished. Therefore, Hiyama Subprefecture became the only subprefecture in which there is no railway.
