Overview

HOSHINOYA Karuizawa is a masterpiece of understated luxury, tucked into the forests of Nagano Prefecture and framed by mountain peaks. Known for its deep sense of calm, architectural elegance, and impeccable service, it's a retreat that invites couples to slow down and reconnect.

Karuizawa has long been Japan's most refined mountain escape — cool summers, vibrant fall colors, and crisp spring air make it ideal for golf and spa travel outside peak heat. The region combines natural beauty with cultural sophistication.

  • Best time to visit: Shoulder seasons, especially fall (September-November) for vibrant autumn colors and comfortable temperatures.
  • What to pack: Layers for mountain weather, golf attire, comfortable walking shoes, casual elegant wear for dining, and light kimono or robe for onsen experiences.

Where to Stay

Accommodations are serene riverside villas with floor-to-ceiling windows, tatami living spaces, deep soaking tubs, and private terraces overlooking water or forest. Interiors are minimalist yet warm — wood, stone, paper, and soft light creating an atmosphere of quiet intimacy.

Nights are peaceful, mornings are gentle, and every space feels intentionally designed for two. The villas embody Japanese design philosophy of harmony with nature and thoughtful simplicity.

Golf

Karuizawa is one of Japan's premier golf regions, home to multiple championship courses set among alpine forests and volcanic foothills. Guests have access to beautifully maintained layouts offering elevation changes, strategic design, and serene mountain scenery.

Whether one partner plays while the other enjoys the spa, or both head out for a shared round, golf here feels thoughtful, quiet, and deeply immersive. The cool mountain climate creates ideal playing conditions during shoulder seasons, and the natural beauty surrounding each hole enhances the meditative quality of the game.

Day Spa

The spa experience at HOSHINOYA centers around natural hot springs and seasonal wellness rituals rooted in Japanese tradition.

  • Open-air onsen pools overlooking forested valleys
  • Shiatsu-inspired bodywork and seasonal therapies
  • Private soaking experiences for couples
  • Meditative relaxation spaces with tea service

It's perfect for couples who value serenity, ritual, and a deeper sense of well-being. The onsen experience connects guests to centuries-old Japanese bathing traditions while the modern spa treatments offer contemporary wellness approaches.

Dining

Dining here is refined and seasonal — kaiseki-inspired menus highlighting mountain vegetables, freshwater fish, and carefully prepared proteins.

Meals are intimate, unhurried, and designed to be savored together — often accompanied by local sake or thoughtfully selected wines. The culinary philosophy celebrates the changing seasons and the bounty of the surrounding mountains, creating a deeply Japanese dining experience.
