JR Hokkaido is extending the Hokkaido Shinkansen from Shin-Hakodate to Sapporo, planned to open in fiscal year 2030. Tunnelling work on the 5,265 m (17,274 ft) Murayama tunnel, situated about 18 kilometres (11 mi) north of Shin-Hakodate station is proposed to commence by March 2015, and be completed by March 2021. If Hokkaido Shinkansen services are ultimately able to be operated at speeds of up to 360 km/h (225 mph), the estimated journey time from Tokyo to Sapporo would be 5 hours and 1 minute.
