Hokkaido Shinkansen
Outline
The Hokkaido Shinkansen is to connect from the city of Hakodate to the city of Sapporo via the city of Otaru.
JRTT is currently constructing the section between Shin-Hakodate-Hokuto and Sapporo.
The line length is about 212 km. The construction plan of the line was authorized by the Government in June 2012, and the groundbreaking ceremony was held in August of the same year.
In January 2015, the Government decided its target completion year in March 2031, five years ahead of the original plan under the precondition that the local governments along the line provide utmost cooperative efforts and supports to the project.
However, some tunnel construction has been delayed by 3 to 4 years due to unexpectedly poor geology with gigantic boulders.
The advisory group is studying steps to be taken.
