Oirase Keiryu Hotel by Hoshino Resorts, the only resort hotel along the Oirase Stream, offers the unique "Luxury Autumn Foliage Hot Spring" experience starting October 7, 2025. This exclusive program allows guests to privately enjoy an open-air bath overlooking spectacular views of autumn foliage and waterfalls, followed by a special Autumn Foliage Champagne Cocktail. Guests can immerse themselves in the luxurious sensation of having the vibrant autumn colors and cascading waterfalls all to themselves, while savoring a Autumn Foliage Champagne Cocktail inspired by the scents and hues of the season. Additionally, the "Hot Spring Autumn Foliage Private Tour," guided by a concierge, will introduce guests to carefully selected hot springs rich in history and culture, allowing them to fully appreciate the vivid autumn foliage of Towada-Hachimantai National Park and the unique charm of various hot springs.
Feature 1: Exclusive Access to an Open-Air Bath with Autumn Foliage Views Like a Painting
This program offers a private reservation of the "Yae Kokonoe no Yu" open-air bath for one group per day. Yae Kokonoe no Yu is a wild and picturesque open-air bath offering vibrant and beautiful autumn foliage scenery. Guests can enjoy the colorful autumn leaves and a waterfall approximately 7 meters high right before their eyes, experiencing nature with all their senses through the murmuring of water, the rustling of trees, and the chirping of wild birds. Soaking in the abundant hot spring water, rich with mineral deposits, while exclusively enjoying the autumn foliage, offers a blissful experience not found in the city.
Feature 2: Indulge in a Luxurious Post-Bath Experience with a "Autumn Foliage Champagne Cocktail"
To ensure a luxurious experience even after warming the body in the hot spring, our hotel's sommelier has carefully selected the "Autumn Foliage Champagne Cocktail," inspired by the autumn foliage's gradation. This cocktail combines champagne with "Vin de Paille," a rich wine characterized by its concentrated flavor made from dried grapes, offering a sweet and complex aroma reminiscent of honey and spices. This fragrance evokes the sweet, caramel-like scent of "Katsura" trees found in the Oirase Stream area during autumn.
Feature 3: A Private Tour to the Hot Spring Autumn Foliage 
On the second day, a Hot Spring Autumn Foliage Concierge, who is deeply passionate about the hot springs and autumn colors of the Towada-Hachimantai National Park area, will guide guests to the most beautiful seasonal foliage spots within the park. The tour introduces distinctive hot springs where guests can immerse themselves in Aomori’s rich culture and centuries-old bathing traditions. From hot springs that preserve the mixed-gender bathing customs of the Edo period to those where two different spring qualities can be enjoyed in one place, the concierge curates the perfect experience unique to the region.
