Ichihara power station was a proposed 1,000-megawatt (MW) coal plant in Chiba Prefecture, Japan.

The project was called off in 2017.

In April 2015 Kansai Electric Power (KEPCO) in collaboration with oil company Tonen General Sekiyu said they planned a coal-fired power station of 1,000 MW in Chiba Prefecture. The total project cost is estimated at several hundred billion yen. They aim to start operation of the plant in the mid 2020s. KEPCO plans to sell some of the power to TEPCO households in the metropolitan area.[1]

In October 2015 Japan’s environment minister Tamayo Marukawa said she won’t support the project, and that Japan should develop a plan to meet its stated goal of reducing greenhouse gas emissions 35 percent from 2013 levels by 2030.[2]

In 2016, Kansai Electric Power and Tonen General Sekiyu continued to move forward with the EIA process.[3]

However, in March 2017 Kansai and Tonen called the project off. In cancelling the plant, the companies cited “changes in the feasibility and the surrounding environment” of the project, which had been questioned by Japan’s environment minister and opposed by many local residents.[4]

In 2016, the Tokyo Shimbun (newspaper) mentioned that the “Ichihara Power Generation Plan” could “Sacrifice Tokyo.”[5]

In the spring of 2017, protests were on the rise in Ichihara against the power plant. Some protestors formed a network called “The Group for Studying the Issues of the CFPPs in Tokyo Bay Area (Anti-Coal Tokyo Bay)”.[6] By March 23, 2017, the Ichihara plant was cancelled after considerations for environment and carbon emissions.[7] The Ministry of the Environment in Japan later wrote an opinion against the Ichihara power plant. They specified that the production of the Ichihara plant would impact air pollution, poor rice and sweet potato production, poisoning due to chlorine leakage, and increased respiratory issues for people in nearby neighborhoods.[8]
