The Hokkaido Oshima Subprefectural Bureau’s Shinkansen Promotion Office submitted a formal request on June 9, 2026 for the continued construction of the Hokkaido Shinkansen between New-Hakodate-Hokuto Station and Sapporo Station. The request is part of the ongoing local advocacy for the on-schedule extension of Japan’s northernmost high-speed rail line.
What happened
The Shinkansen Promotion Office coordinates the position of Oshima region municipalities regarding the ongoing Shinkansen extension project. The June 9 submission reiterates the region’s support for continued construction work, and typically covers both funding continuity and operational planning issues that affect the extension’s schedule.
Why it matters
The Hokkaido Shinkansen extension from New-Hakodate-Hokuto to Sapporo is one of Japan’s largest ongoing rail projects and is expected to significantly reduce Tokyo-Sapporo travel times once complete. Regional advocacy is a routine but important part of the political and administrative process that shapes the project’s timeline and priorities.
