On September 14, JR Central announced at a resident meeting in Gifu’s Mizuho City that it will compensate households affected by water source depletion from Chuo Shinkansen maglev tunnel construction for 30 years after excavation ends—the maximum under national public works standards.

In Oi district, households unable to use wells due to water level decline switched to municipal water; JR Central will make lump-sum payments covering the increased costs for 30 years. Additionally, it drilled new deep wells for 35 households.

On September 14, JR Central outlined compensation for Oi Town, Mizuho City (Gifu), where Chuo Shinkansen maglev tunnel work lowered groundwater and surface levels, following national public works standards.

The plan covers 30 years of increased water management costs: after tunnel excavation ends and deep well operations are confirmed, JR Central will make lump-sum payments for maintenance costs exceeding original water sources. For households switching to municipal water or using new deep wells, JR Central will cover 30 years of associated fees. Surface-level subsidence fixes (e.g., door adjustments) continue until stabilization, with final compensation details to follow. Excavation, halted since May 2024, awaits a 5-month horizontal boring survey starting around October, though a restart date remains unclear.
