Shinkansen trains operate through the tunnel to Shin-Hakodate-Hokuto Station in Hakodate, connecting Tokyo and Shin-Hakodate-Hokuto stations in four hours and two minutes, at a maximum speed of within the tunnel and outside it, and to the south of Morioka. It was expected that by 2018 one daily service will be run at through the tunnel. In March 2019, a 160 km/h speed limit inside the tunnel allowed Tokyo-Shin-Hakodate services in 3h58. The final stage is proposed to open to Sapporo Station in 2031 and is expected to shorten the Tokyo-Sapporo rail journey to five hours. The Hokkaido Shinkansen will be operated by JR Hokkaido.
