SHIMUKAPPU, Hokkaido--A luxury hotel here is offering guests the memorable experience of spending the night in a sub-zero room made entirely out of ice.

Yes, you read that correctly.

Hoshino Resorts Tomamu, situated in a town at the center of the northernmost prefecture, has opened a winter-only accommodation called "Ice Hotel" as part of its outdoor "Ice Village," where everything is made of ice.

The dome-shaped accommodation, measuring about 8.5 meters in diameter and 3.5 meters high, comes with basic furnishings such as a chair and a table--all made of ice.

The average temperature inside the room is below zero, but the solid walls and ceilings--they are made of ice as well--shelter guests from biting winds.

Those who opt for the experience are provided with pillows, a comforter and sleeping bags to stay warm. An open-air hot spring bathtub is also available.

The frosty accommodation was built when temperatures dipped to below minus 14 degrees by inflating a sheet into a semi-circular shape, then pouring water over it and waiting until it froze.

Guests can book the overnight experience for an additional 23,000 yen ($210) per person, including tax and service charges.

Unfortunately, the resort is fully booked for this season.

The Ice Hotel, however, is open to spectators from 5 p.m. to 9:30 p.m. until the end of February. Entry to the Ice Village is 500 yen and free for resort guests.
