The extension of the Hokkaido Shinkansen to Sapporo has been delayed by eight years, with the new target opening set for March 2039, according to sources.
Reasons for the Delay
- Tunnel Construction Difficulties: Challenges due to large-scale bedrock and soft ground.
- Labor Shortages in the Construction Industry.
Outline of the Sapporo Extension Section
- Section: From Shin-Hakodate-Hokuto Station to Sapporo Station (212 km).
- Tunnel Proportion: About 80% of the section will be tunnels.
- Route: Passes through the Niseko Ski Resort area.
Initial Plans and Revisions
- 2012: The government approved the plan.
- Original Target Opening: Spring 2031 → Revised to March 2039 (8-year delay).
- Project Cost:
- Originally: 1.67 trillion yen (~$11.6 billion USD).
- Revised in 2022: 2.3 trillion yen (~$15.9 billion USD) (primarily due to rising material costs).
Current Status of the Hokkaido Shinkansen
- Opened: March 26, 2016.
- A high-speed rail line connecting Tokyo and Hokkaido, passing through the Seikan Tunnel.
- The extension to Sapporo is expected to enhance travel convenience within Hokkaido and boost tourism, but concerns remain about further cost increases and potential delays in the construction timeline.
