60:, as the government remained unsure about the future of nuclear power in the country. Building the thermal power plant designed to use coal from the mine is expected to keep the mine in operation for a few decades, but not at full capacity. Managers at the mine concede "that its continued existence is largely an anachronism, not indicative of any longer-term future for coal in this country or for the East Asian region in general." In particular, production costs of coal from the mine cannot compete with large open pit operations in Australasia or elsewhere in Asia.

Local residents are of mixed opinion about the mine, questioning its reduced output and need for the coal.

Output has been decreasing, from 5 million tons/year, dropping to 700,000 tons when KCM took over the mine. As output of the mine decreased, trains carrying coal from the mine were eliminated in 2019. Some output (300,000 ton) is being used at the

The local coalfield was formed around 38 million years ago, from the rich peatlands around the area. The field has more than 10 seams capable of being mined, some up to 5 meters thick. Coal mining has been an important part of the local economy since large scale extraction began in 1920. At one time,

Water drainage from the mine has been shown to help predict earthquakes in the area. Water drainage from the Mine decreased on the day of all M ≥ 7.5 earthquakes with an epicenter of 300 km from the mine and increased thereafter. Scientists are hopeful that these findings can help predict “pre-

Taiheiyo Coalmine Co was known for the modernization of its management structure over a period of 10 years in the 1960s. "The measures introduced by Taiheiyo in the 1960s dramatically changed key areas of corporate management, such as employee status, wages, labor-management relations, housing

The current mine is composed of rusting silos and long corrugated steel structures along the north side of the property. These structures house conveyor belts carrying coal to be processed and loaded onto waiting trucks. Located along the south side of the mine are administrative buildings and

As of the 1990s, the mine produced 25% of all domestic coal used by power stations in the country. At that time, 80% of the mine's production was done by mechanized longwall mining, used since 1967. Paleogene bituminous coal is extracted from under the ocean floor at the site.

was established to take over the operations on the site. Since the early days of the mine, mechanization was deemed essential on the site, as it was impossible to build a vertical mine shaft, given the undersea location.

The mine has been involved in technical and environmental information sharing with other Asian coal-mining countries and has operated human capital exchange programs to support these efforts.
