The museum name 'Horuru' is derived from a combination of 'horu' (to dig) and the German 'ru' (from 'Ruhr', the famous German coal region).
It houses a massive fossil of the Futabasaurus suzukii, which was the first plesiosaur ever discovered in Japan.
The simulated mine tour allows visitors to walk through actual retired tunnels from the Joban Coal Mine.
The museum displays artifacts from the Edo period, showing the early use of 'black gold' (coal) in the Iwaki region.
The museum sits directly atop the former Joban coal mine site, integrating real industrial heritage into the exhibit space.
Exhibits explain how the coal mine industry directly facilitated the development of the famous Yumoto hot springs due to drainage projects.
The Iwaki City Coal & Fossil Museum, locally known as Horuru, is dedicated to the history of the Joban Coalfield and the region's paleontological discoveries. The facility features a simulated underground coal mine experience that descends into historical mining tunnels. The fossil wing displays large-scale reconstructions of prehistoric marine life, including the Futabasaurus suzukii, a plesiosaur discovered in the nearby Futaba Group strata. Visitors can walk through reconstructed mine galleries that demonstrate the evolution of coal extraction technologies. The museum integrates geological history with the industrial development of Iwaki City. It serves as a comprehensive archive of the Joban region's transition from an energy-producing coal hub to a center for natural history research.

Wear comfortable walking shoes for the mine tour, as the path involves simulated tunnels and slightly uneven flooring.
Allocate extra time to read the placards in the fossil wing, as they detail the specific geological strata found in the Fukushima region.
Do not rush through the underground mine section, as it is the most unique part of the museum and provides the best context for the local history.
Closed on the third Tuesday of each month; if that Tuesday is a national holiday, it closes the following day.
