Overview

When you arrive at Kasuitei Ooya, you step into a lakeside retreat shaped by the calm beauty of Lake Kawaguchi and the towering presence of Mount Fuji. The ryokan sits close to the water, giving you wide views that shift throughout the day—from quiet morning reflections to soft evening colors. Warm wood, gentle lighting, and thoughtful design welcome you the moment you enter, helping you slow your pace and ease into a relaxing stay.

You enjoy an atmosphere built around comfort, attentive service, and traditional touches. Whether you want to unwind in soothing hot spring baths, savor seasonal meals, or use the ryokan as a base for exploring the Fuji Five Lakes region, Kasuitei Ooya gives you a peaceful and inviting home during your visit.

Accommodation

Your room at Kasuitei Ooya gives you space to stretch out and enjoy a slow rhythm. You can choose from Japanese-style rooms with tatami floors, Western-style rooms with beds, or mixed layouts that offer both. Each room uses simple design, calm colors, and natural textures that help you settle in from the moment you step inside.

Many rooms offer views of Mount Fuji or Lake Kawaguchi. You can watch the mountain glow in the early morning or see the lake shimmer as the day moves into evening. Some rooms include private open-air baths, allowing you to soak while looking at the scenery. These private baths become one of the most memorable parts of your stay—especially when you bathe at night under clear skies.

Each room includes yukata, tea sets, toiletries, and seating that lets you enjoy quiet moments with a warm drink or a view of the lake. You always have what you need to relax and enjoy your stay without rushing for anything extra.

Dining

Your meals at Kasuitei Ooya highlight the flavors of Yamanashi’s fields, rivers, and mountains. At dinner, you enjoy dishes crafted with seasonal ingredients such as local vegetables, river fish, tender meats, and carefully prepared broths. Chefs present each course with care, bringing color and balance to your table.

You may enjoy sashimi, grilled dishes, simmered vegetables, small side plates, and warming soups that reflect the season. You move through each course at a gentle pace, giving you time to savor every texture and flavor.

In the morning, you start your day with breakfast that supports your energy whether you plan to explore or relax in the baths. You enjoy items such as grilled fish, rice, eggs, soups, and small dishes made from fresh ingredients. The morning meal helps you begin your day feeling steady and refreshed.

Onsen and Wellness

The ryokan’s hot spring baths draw from a natural source known for its gentle mineral qualities. You feel the warmth settle into your muscles the moment you step into the water.

Kasuitei Ooya offers indoor baths, open-air baths, and private options that let you choose the atmosphere you prefer. Indoor baths give you wide pools where you can stretch and relax. Large windows bring in soft light and, in some areas, views of the lake.

Open-air baths let you soak while breathing fresh air and enjoying the natural surroundings. Warm steam rises into the sky as you look out toward Lake Kawaguchi or nearby hillsides. Early mornings and evenings create especially beautiful moments when the air cools and the water feels even more comforting.

After bathing, you can unwind in relaxation areas, hydrate, and enjoy the lingering warmth that stays with you long after you leave the water.

Guests with Tattoos

If you have tattoos, you can enjoy the baths by reserving a private bath. You simply book a time at the front desk. This gives you a comfortable and personal space where you can relax freely at your own pace.
