KUSATSU, Gunma Prefecture--Fancy gliding down a mountain before taking a hot bath?

One of Japan's top onsen resorts has added another reason to visit: A zip line.

The new attraction, called BanZip Tengu, opened April 27 at the Kusatsu Onsen Ski Resort.

The zip line starts from the top of the 1,370-meter-tall Mount Tenguyama, offering riders a view overlooking the hot spring town.

Wearing a harness suspended from a wire cable, riders can travel down the line with the help of a pulley. Covering 500 meters and with a height difference of 108 meters, the BanZip Tengu is touted as Japan’s steepest zip line, with a maximum speed of 70 kph.

The ski resort was forced to shut down its signature long-distance route and a ropeway owing to the eruption of Mount Moto-Shiranesan, part of the Kusatsu-Shiranesan mountains, in January last year. It renamed itself from Kusatsu International Ski Resort to make a fresh start as a ski destination intended for families and beginners and intermediate-level skiers. The zip line was installed to entertain visitors throughout the year.

A test ride event was held April 24, during which Waseda University students who were visiting the town as part of a class on urban design also tried the contraption out.

“I could see the sprawling landscape and it felt great,” a male student said.

The zip line is open to elementary school students or older, and riders must weigh at least 25 kilograms and be under 110 kg.

The charge is 2,000 yen ($18) for adults and 1,200 yen for elementary school students.
