Japan's ruling parties have reaffirmed the decision to extend the Hokuriku Shinkansen from Tsuruga to Shin-Osaka via the Obama-Kyoto corridor [1].
The decision settles a critical infrastructure dispute regarding the most efficient way to connect the Hokuriku region with the nation's western economic hub. This extension is vital for regional connectivity and tourism, though it remains a point of contention for local governments regarding the financial burden of construction.
The ruling-party committee, consisting of the Liberal Democratic Party and the Japan Innovation Party, confirmed the route during a meeting on Oct. 30, 2026 [2]. According to the Ministry of Land, Infrastructure, Transport and Tourism, the Obama-Kyoto corridor provided the highest benefit-cost ratio for the Tokyo-Shin-Osaka segment [3].
Officials evaluated eight different route proposals for the extension [4]. While some individual evaluations suggested the Maibara route's transfer plan scored a 1.0, the highest in that specific metric [5], the government's overarching cost-effectiveness analysis favored the Obama-Kyoto path [3].
As part of the plan, a new Kyoto station will be established near JR Keikawa Station [1]. This placement aims to integrate the high-speed line into the city's existing transit network, while minimizing disruption to the historic center.
Despite the federal push, some local leaders expressed caution. Kyoto Mayor Matsui Kōji said the fiscal burden is a concern [6]. The project involves complex tunneling and land acquisition in densely populated and geographically challenging areas.
The extension will start in Tsuruga, Fukui Prefecture, pass through Obama, and continue through Kyoto before terminating at Shin-Osaka [1, 7].
“The Obama-Kyoto corridor provided the highest benefit-cost ratio for the Tokyo-Shin-Osaka segment”
The reaffirmation of the Obama-Kyoto route prioritizes long-term economic efficiency and direct connectivity over the potentially lower-cost Maibara alternative. By selecting this corridor, the Japanese government is committing to a more ambitious engineering project that aims to maximize the utility of the Shinkansen network for travelers between Tokyo and Osaka, despite the ongoing friction with local municipalities over funding and urban disruption.
