The Industrial Waste Dumping Incident in Kutchan, Hokkaido – December 1997 The illegal dumping of industrial waste uncovered in Kutchan, Hokkaido, in December 1997 had a serious impact on the local environment. In this incident, a construction company illegally dumped debris from demolition work, including scrap materials, concrete fragments, and plastic waste, on vacant land on the outskirts of the town. The estimated volume of dumped waste reached approximately 250 tons, of which 75 tons—about 30%—consisted of waste containing hazardous substances. The incident began with a report from a local resident. Concerned by the foul odor and the sight of waste scattered across the site, the resident consulted the local government, prompting an investigation. The investigation confirmed that the waste contained lead and cadmium, revealing a high risk of soil and groundwater contamination. Consequently, concerns arose regarding the risk of groundwater contamination extending ov
er an area with a radius of more than one kilometer. The contractor responsible for the illegal dumping is believed to have engaged in this illegal activity to reduce disposal costs by failing to properly process the waste. The estimated cost savings for this contractor are said to be approximately 10,000 yen per ton, totaling about 25 million yen. Meanwhile, as an emergency measure, the local government carried out the removal of the waste, with approximately 35 million yen in public funds expended for this purpose. Following the incident, Kutchan Town strengthened its monitoring system for waste disposal to prevent recurrence, installing surveillance cameras and conducting patrols to deter illegal activities. Additionally, the town intensified guidance for waste disposal operators within its jurisdiction and promoted awareness campaigns among local residents.

This incident served as a catalyst for local residents and the government to unite in addressing the issue of illegal dumping. Since then, Kutchan Town has continued to strive to raise environmental awareness and promote proper waste disposal practices. Nationally, this incident highlighted challenges in industrial waste management and served as a reminder of the importance of proper disposal.
