Karuizawa, one of the most prestigious onsen areas in Japan, is nestled in the eastern foothills of Mount Asama in Nagano Prefecture. Its high altitude and cool climate make it a favored retreat during the hot summer months. Karuizawa is renowned for its distinctive hot springs, known as hoshino onsen, whose mineral-rich waters are said to have healing properties and are a delight to soak in amidst the surrounding natural beauty.
The charm of Karuizawa extends beyond its relaxing onsen. Its blend of nature, culture, and history makes it a unique destination. Visitors can enjoy leisurely walks through lush forests, visit the charming old churches, or explore the local shopping district, Ginza-dori, known for its exclusive boutiques and art galleries. The area also boasts a selection of ryokan (traditional Japanese inns) where guests can stay and savor the authentic Japanese hospitality.
