HOTEL OOSADO

Out on Sado, off the coast of Niigata Prefecture, nature and history sit side by side. Set at Aikawa Kasugazaki on the island’s scenic west coast, HOTEL OOSADO has welcomed guests since 1964. All 72 guest rooms overlook Sado’s dramatic sea, and the evening sunsets are particularly striking. Renovations in 2023 and 2024 refreshed the Premium Suite Rooms, along with the Water Terrace, lounge, restaurant, and large public baths, with a more modern look.

Choose from eight room types, from limited Premium Suite Rooms (only two) with private open-air hot spring baths to oceanfront Japanese-style rooms with a modern twist. Every room is oceanfront with large windows, so you can relax and watch the ever-changing colors of the sea and sky from the comfort of your room. For hot springs, the hotel offers open-air baths, spacious indoor public baths, and a sauna—especially impressive is the view from the open-air bath, where breathtaking scenery of the Sea of Japan spreads out right in front of you.

Dining features Japanese cuisine that makes the most of Sado’s blessings from both the mountains and the sea. Seasonal local ingredients take center stage throughout the year—wild mountain vegetables in spring, crab, rock oysters, and abalone in summer, mushrooms in fall, and winter specialties like yellowtail and oysters.
