Shikoku Shinkansen Plan Revived After 53 Years

The Japanese government has initiated preliminary studies for a Shinkansen railway service to Shikoku, a development that hasn't been seriously considered in 53 years. This marks the first major development in plans that have been on hold for more than half a century. The transport ministry plans to assess potential routes, station locations, and passenger demand along a Shikoku network extending from Okayama to the island's prefectural capitals.

If this project advances, travel times from Shin-Osaka to major cities such as Tokushima, Takamatsu, and Matsuyama could be reduced to approximately 90 minutes. The Okayama-based route is seen as more feasible due to the Seto Ohashi bridge, which already has space for Shinkansen tracks, unlike the Akashi Kaikyo Bridge which is currently used only for highway traffic.

Local governments in Shikoku and regional business groups have been advocating for the Okayama route, and their support has led to the transport ministry's decision to begin studies. The potential economic impact of a Shikoku Shinkansen is estimated at around 16.9 billion yen annually. However, the project remains at an early stage, with the initial study focusing on broad route options, possible station locations, and estimated demand.

The final decision on whether to proceed with the development plan will depend on comprehensive statutory investigations, political approval, and construction costs.
