Takine Goten, the great hall of Abukumado Cave

Discovered in 1969, Abukumado Cave (あぶくま洞, Abukumadō) is a 3000 meter long limestone cave network in eastern Fukushima Prefecture, about 35 kilometers northwest of Iwaki. The spacious caverns were formed over 80 million years by underground streams, and contain countless stalactites and stalagmites of many different varieties. Abukumado Cave exhibits some unique and rare features that cannot be seen elsewhere in the country, including boxwork formations and the Christmas Tree, a two meter high stalagmite that is said to be the largest stalagmite in Asia.

About 600 meters of the caverns are opened to the public and are accessible by a series of well developed platforms, paved walkways and (often steep) staircases. It takes about an hour to explore the main walking course though the cave, and while the tunnels can be narrow at times, they are, for the most part, easily traversable. The cave uses a stage lighting system to creatively light some of its chambers including its impressive Takine Goten main hall.

More adventurous visitors can take an optional, 120 meter long exploration course which leads through a narrow side tunnel running parallel to the main course. As expected, the exploration course is more difficult to negotiate, and may require visitors to crawl through on their hands and knees at times. Also an additional, small fee is required which can be paid at the above ground ticket counter or inside the cave. The exploration course rejoins the main course in the Takine Goten hall.

A few other attractions can be found around the mouth of Abukumado Cave including restaurants, souvenir shops and the Star Village Observatory and Planetarium just across the parking lot. Additionally, the hillside between the cave and the planetarium is covered in over 50,000 lavender plants which flower from mid June to early July.
