Hoshinoya Karuizawa opened on July 20, 2005 in Karuizawa, Nagano Prefecture, as the starting point of the "Hoshinoya" brand, where each property offers an overwhelmingly extraordinary experience based on a unique theme. The concept is "stay in a valley village. Surrounded by nature at the foot of Mt. Asama, the valley village evokes the original landscape of Japan. The guest rooms are separated from the rest of the house and are surrounded by water, offering a view of the four seasons from the rooms. The spa offers two types of hot springs with different atmospheres and relaxes the body and mind. The hotel also offers a variety of experiences, such as meals that savor the flavors of Shinshu and activities based on "eco-tourism," to provide a moment of rest and relaxation.
