 The Hokkaido Shinkansen route north of Shin-Hakodate-Hokuto approximately parallels the route of the Hakodate Main Line, with stations proposed to be built at Shin-Yakumo, Oshamambe, Kutchan, Shin-Otaru and Sapporo.Until the opening of the Hokkaido Shinkansen, these services usually operated on the 1966 built Nanae to Ōnuma section, bypassing (then) Oshima-Ono and Niyama.Now that Shin-Hakodate-Hokuto (formerly Oshima-Ono) is the major connection between the Hokkaido Shinkansen and "zairaisen" (local line) services on the Hakodate Main Line, these services have been re-routed accordingly.
