リニア工事のリアル_樫田秀樹氏_大井川の水を守る62万人運動

The video titled “リニア工事のリアル_樫田秀樹氏_大井川の水を守る62万人運動” presents a detailed study session focused on the realities and challenges surrounding the construction of the Linear Chuo Shinkansen (maglev train) project in Japan. It particularly highlights the environmental and social impacts on the Oi River region and surrounding prefectures.

Key Points and Main Arguments

1. Introduction and Context

The session is organized by a citizen movement of about 620,000 people dedicated to protecting the water of the Oi River.
Mr. Hideki Kashiwada, a freelance journalist specializing in the Linear Shinkansen for over 10 years, leads the discussion.
The Linear Shinkansen project is significantly behind schedule, with expected openings pushed back decades beyond the original 2027 target:
- Nagoya segment projected for mid-2040s
- Osaka segment after 2060s

2. Responsibility and Accountability

Kashiwada identifies six responsible parties for the project’s issues:
- JR Central
- Local governments
- National government
- Media
- Experts
- Judiciary
He emphasizes that failure of any one party to act responsibly contributed to the current problematic state.
The U.S. Maglev project was canceled due to environmental and public opposition, serving as a cautionary example.

3. Construction Delays and Technical Challenges

Tunnel excavation progress is roughly 19%, but overall project progress including guideway installation and electrical/mechanical work is around 10%.
Specific tunnels such as:
- Koma Tunnel in Gifu Prefecture
- Southern Alps Tunnel in Yamanashi Prefecture are progressing very slowly, with excavation alone expected to take over a decade.
JR Central has repeatedly made misleading public statements about construction progress and timelines.

4. Environmental and Social Impact

Water depletion and damage to local water sources have occurred, notably in Gifu Prefecture, causing significant concern among residents.
Citizens’ groups have had to step in due to inadequate responses from JR Central and local governments.
Past experiences with the Linear experimental train in Yamanashi Prefecture showed water shortages and insufficient compensation guarantees.
Ground subsidence and groundwater contamination have been observed near construction sites.
Chemical injections and other environmental protection measures have been inconsistently applied or delayed.
Heavy metal contamination (cadmium, chromium, mercury, lead, zinc) and radioactive materials (uranium and radon gas) present serious environmental and health risks in some regions.
Temporary storage and disposal of excavated soil and waste remain unresolved, with unclear plans and insufficient transparency.

5. Local Government and Community Relations

Local governments often show passivity or inadequate engagement with residents’ concerns.
Some mayors and officials have downplayed or ignored water depletion and environmental damage issues.
Residents face forced relocations and property devaluation due to construction plans.
Public information sessions by JR Central have been criticized for vague or dismissive responses, limiting residents’ ability to ask questions.
Citizen movements have been vital in documenting problems, collecting data, and pushing for accountability, but cooperation among regions and groups is still weak.

6. Environmental Conservation and “Nature Positive” Initiatives

The concept of “Nature Positive” (NP) aims to create environments better than those lost due to construction.
There is skepticism about the feasibility and sincerity of NP measures, given limited environmental surveys and lack of comprehensive data.
The environmental impact assessment and compensation plans are viewed as insufficient or superficial by citizens and experts.

7. Media and Information Transparency

The media often fails to conduct thorough fact-checking, especially regarding delays and environmental impacts.
Information is sometimes withheld or manipulated by JR Central and related agencies.
Citizen groups have had to independently gather and publicize data to counter official narratives.

8. Future Outlook and Citizen Action

The movement to protect the Oi River and surrounding areas is reorganizing with co-representatives to strengthen efforts.
Upcoming study sessions and public forums are planned to increase awareness and coordination.
Kashiwada stresses the importance of science-based activism, data collection, and persistent citizen engagement to influence policy and project management.
Despite challenges, there is a renewed resolve among citizens to continue opposing harmful practices and demand transparency and environmental protection.
