BUNGO-ONO, Oita Prefecture--Divers have discovered a cavern of great proportions within the Inazumi Underwater Stalactite Cave here in southwestern Japan, believed to be the longest of its kind in the country.
Surveys in the 1970s and 1990s confirmed the Inazumi cave contains about 1,000 meters of water channels, part of which are open to the public.
Earlier this month, a team of adventurers, led by 53-year-old Hitoshi Miho from Kanagawa Prefecture, advanced about 300 meters from the innermost known part of the cave.
There they reached an air pocket above the water measuring about 10 tatami mats and found a narrow stalactite hole that leads even farther into the cave.
Though the gaping entrance enticed the divers, they did not venture into it.
Another team led by Masayoshi Kondo, a 56-year-old cave diver from Okinawa Prefecture, is planning an expedition from Feb. 23 to conduct detailed measurements.
