Shizuoka Governor Suzuki Yasutomo is moving toward starting construction on the final 8.9 km segment of the Linear Central Shinkansen [4].
The resolution of this specific gap is critical for the completion of the maglev line, which has been stalled for years due to environmental disputes. The project aims to connect major Japanese cities with a train reaching top speeds of 500 km/h [1].
For approximately nine years, former Governor Kawakatsu Heita opposed the project [6], and said, "リニアはいらない" (I do not need the Linear) [0]. This opposition created a significant bottleneck in the 285.6 km total length of the line [2], where tunnels make up about 86% of the route [3].
Following the change in governorship in June 2026, the political climate in Shizuoka has shifted. Governor Suzuki has expressed a more supportive stance and a desire for speedy handling of the project. Regarding the timeline for breaking ground, Suzuki said, "2年も3年も先ということはない" (It will not be two or three years away) [7].
To facilitate the agreement, JR Central has offered the prefecture additional stops for the Hikari Shinkansen. President Niwa of JR Central said the company intends to negotiate these terms and summarize them in a formal document [8].
While political will has increased, environmental concerns regarding the Oi River remain a point of negotiation. Despite these hurdles, the project reached a milestone in May 2026 when the tunnel breakthrough occurred within Yamanashi Prefecture [5].
Some reports suggest the exact date for the construction start remains unclear, but the current administration's momentum marks a departure from previous years of deadlock. If construction begins soon, the line could potentially open in about 10 years [9].
“"I do not need the Linear"”
The shift in Shizuoka's leadership removes the primary political obstacle to Japan's most ambitious infrastructure project. By moving from a position of outright opposition to one of negotiated cooperation, the prefecture allows JR Central to finalize the South Alps Tunnel. This transition suggests that economic incentives, such as increased Shinkansen access, are successfully outweighing the environmental objections that previously paralyzed the project for nearly a decade.
