Where the Ashes Go: The Shift in Environmental Administration That Began in Tokorozawa (1997-2000)
In the late 1990s, Japan was at a turning point in rethinking its incineration-centered waste disposal system. Waste incinerators, which were regarded as the main cause of dioxin pollution, caused social unrest, forcing environmental administration, companies, and residents to respond from their respective standpoints. Tokorozawa City in Saitama Prefecture is particularly symbolic. In 1999, a TV program reporting dioxin contamination of vegetables caused a nationwide sensation. The city immediately enacted Japan's first dioxin control ordinance and proceeded to collect and remove small household incinerators. This move by Tokorozawa was the beginning of an environmental leadership policy by local governments, which later spread nationwide.

In 1997, the Ministry of Education notified the government that school incinerators were to be abolished in principle, and about 90% of public schools stopped using them. The Basic Guidelines for the Promotion of Dioxin Control Measures formulated in March 1999 set a national target of reducing dioxin emissions by 90% from the 1997 level by 2002, and the Environment Agency and the Ministry of Health and Welfare collaborated to establish clear standards for the construction and operation of incinerators. As a result, concentration regulations were introduced for incinerators with a grate area of 2 square meters or more or a processing capacity of 200 kilograms per hour or more, marking a period of major technological change.

At the time, Japanese society had a shaky trust in science and technology. Trace amounts of dioxin detected in incinerator exhaust gas and fly ash became a symbol of people's "invisible anxiety. The Tokorozawa mother's milk survey and reports of vegetable contamination pushed environmental risks to become a central issue in daily life through the media, forcing the government to balance "scientific rationality" and "social security. This tension created a chain of events in which citizens' voices changed policies and administrative responses encouraged technological innovation in industry.

At this time, when the era of incineration universalism was ending and people began to seek a path toward recycling and a recycling-oriented society, Japan's environmental policy shifted from "technological administration" to "dialogue administration. Tokorozawa's ordinance was a pioneering example of how local autonomy can lead the national environmental policy, and it can be said to have shaped the prototype for environmental governance in the modern era.
