Overview

Located in the quiet hills of Hakone Yumoto, Hotel Kajikaso welcomes you with the sound of the Hayakawa River and a view of distant mountains. This ryokan blends peaceful surroundings with the comfort of natural hot springs drawn from nine sources. During early summer, you may even hear the call of the kajika frog—an experience that adds to the charm of your stay.

Let the rich waters of Hakone’s famous onsen wash away your fatigue. Whether you’re here for a break from the city or a journey through Japan’s natural beauty, Hotel Kajikaso offers you a place to truly unwind.

Accommodation

Hotel Kajikaso offers a wide range of rooms to suit your style. Choose from classic Japanese-style rooms, hybrid Japanese-Western rooms, or suites with private open-air baths.

Relax in a space that feels like a personal retreat. Each room is designed to provide comfort and calm, whether you want to stretch out on tatami mats, enjoy the scent of fresh wood, or soak in your private bath while listening to the sound of the river below.

Rooms are organized into distinct areas, including the serene “IKOI” floor, the elegant “Kisaki,” and the refined “Shusui-an.” No matter which space you choose, you’ll find a quiet place to call your own.

Dining

One of the highlights of your stay at Kajikaso is the food. The chefs prepare seasonal kaiseki meals using fresh seafood from Sagami Bay, select domestic wagyu beef, and local produce. Every dish is crafted with care and served with attention to presentation and balance.

Dinner is served in one of two dining rooms. The Aoi Dining Hall offers a more open atmosphere, while Restaurant Nishiki features a more intimate, refined setting. Each month, the menu changes to reflect seasonal ingredients at their peak, delivering a true taste of Japan’s shifting seasons.

Start your morning with a traditional Japanese breakfast featuring local rice, fish, and vegetables. The meal is light, nutritious, and satisfying—a perfect way to begin your day in Hakone.

Onsen and Wellness

With nine private sources, Hotel Kajikaso delivers rich, mineral-filled waters to every bath. Enjoy the views from the 6th-floor observation bath “Seiryu no Yu,” where large windows open to the Hakone landscape. Soak in the barrel-shaped hinoki bath or relax in the open-air rock baths on the wood terrace.

On the 2nd floor, the “Soun no Yu” area features wide indoor baths and open-air hot springs. Stretch out in the 18-meter-wide tub, then step into “Kajika no Yu” or “Utata-ne no Yu,” where you can fully unwind in the gentle, scentless alkaline spring water.

All baths offer space and atmosphere that help you feel grounded and calm. Whether you gaze at the mountains, listen to flowing water, or sit in quiet steam, you’ll find a moment of healing in every soak.

Guests with Tattoos

You can use the public baths regardless of tattoos. Enjoy the onsen facilities freely and comfortably during your stay.

Facilities

Hotel Kajikaso is designed for both relaxation and entertainment. When you arrive, a bamboo garden greets you at the entrance, showing different expressions through each season. In the lounge “Seseragi,” enjoy coffee, tea, or a cold drink while looking out over nature.

Soak your feet in the riverside footbath, open from sunrise to sunset. It’s the perfect place to rest while surrounded by open skies and flowing water.

The ryokan also includes lounges, banquet halls, meeting rooms, and unique spaces for nighttime fun. Visit Club “Saika,” the Birdie Salon, or the karaoke rooms “Orihime,” “Otohime,” and “Utahime” for a lively night. You can also stop by the ramen shop “Hachiri” for a late-night bite, or browse local sweets and gifts at the souvenir shop “Fujimi.”

Activities

Spend time walking through the garden, watching the light change over the bamboo and stones. Talk with friends over drinks, enjoy seasonal displays of flowers, or explore Hakone’s nearby sights.

The staff also regularly refresh the lobby and public areas with seasonal touches, ensuring each visit feels unique and personal.
