Kamenoi Hotel Tsukubasan

Kamenoi Hotel Tsukubasan is a sky-high Onsen resort with sweeping views over the Kanto Plain! From the infinity open-air bath that feels connected to the sky, enjoy views of Mt. Fuji by day and a glittering panoramic nightscape—often called “the starry sky on earth”—by night. Savor Ibaraki’s seasonal bounty with a luxurious buffet featuring mountain-and-sea rice bowls and a live kitchen, and don’t miss the popular complimentary evening service, “Hell Tour Tantanmen.” We promise an exceptional escape and deep relaxation.

Enjoy a liberating sense of openness with sweeping views over the vast Kanto Plain, and the soothing comfort of Tsukuba’s greenery. From distinctive Japanese-style and Western-style Rooms to slightly luxurious Rooms with scenic open-air baths, kid-pleasing kids’ Rooms, and dog-friendly Rooms where you can stay with your beloved pet, we cater to each guest’s “ideal trip.”

Northern Kanto is packed with pride-worthy ingredients, including The whole country’s top-producing farm products and premium branded beef. We offer a buffet featuring seasonal local ingredients and Northern Kanto’s distinctive food culture. The nebuta displayed in the restaurant depict Izanagi-no-Mikoto and Izanami-no-Mikoto. “Matsuri Tsukuba,” held in August, is a festival where nebuta appear on a scale second only to those in the Tohoku region.

The “Infinity Open-Air Onsen,” offering breathtaking views from the mid-slope of Mt. Tsukuba, is one of our Hotel’s highlights. The spring water that wells up at the foot of Mt. Tsukuba is an alkaline simple Onsen, also known for its skin-beautifying qualities. A natural Onsen that refreshes both body and mind.
