3. The Art of the Japanese Ryokan Stay & Kaiseki Dining
A stay at a traditional Japanese “Ryokan” is an experience where the accommodation itself becomes the highlight of your journey. Unlike a luxurious Western hotel, the value here lies in tradition, tranquility, and meticulous “Omotenashi (Hospitality)”.
🧖♀️ Your Extraordinary Day at a Ryokan
From the moment you step into the inn, your journey begins. Enjoy a timeless experience where the hours seem to slow down, from check-in to check-out.
- 1. The Luxury of Spending Time in a Yukata
- ・Changing into a Yukata: After checking in, the first step is to change into the “Yukata” provided in your room. This is the Japanese traditional relaxation garment, and it is customary to wear it throughout the inn.
・Sense of Freedom: Walking around the facility or going to the Onsen in a yukata offers a sense of freedom and relaxation unavailable in Western clothing.
- 2. The Culture of Onsen First
・Reset with the Onsen: It is a tradition at Japanese Ryokans to first visit the hot spring to wash away the fatigue of travel, typically before dinner.
・Multiple Dips: Enjoying the Onsen multiple times—after dinner, before bed, and early in the morning—is the Japanese way to experience luxury. It is recommended to try different spring qualities or enjoy the changing scenery throughout the day.
- 3. Savoring “Quiet Time in Your Room”
The Room is Your Private Space: The main event at a Ryokan is simply enjoying the quiet time in your own room. Many inns provide tea and snacks upon check-in, allowing you to peacefully watch the garden, read, or simply relax in the zaisu (floor chairs).
Futon Bedding: During dinner, staff will enter your room to prepare your Futon bedding. This moment is another unique Ryokan service that emphasizes the feeling of stepping outside the everyday.
🍽️ The Essence of Kaiseki: A Seasonal Japanese Full Course
Kaiseki cuisine is one of the biggest factors that elevates the value of a Ryokan stay. It is not merely a meal, but a full course designed to delight all five senses with Japanese art and the changing seasons.
- 1. “A Seasonal Story” in Every Dish
・The Art of Seasonal Ingredients: Kaiseki uses “Shun” (seasonal) local ingredients, such as spring wild vegetables, summer Ayu (sweetfish), and autumn mushrooms/chestnuts. In the Nikko area, the cuisine is often enhanced by freshwater fish from the clean streams, local brand beef (Tochigi Beef), and the famous Yuba (tofu skin).
・The Course Progression: The meal is served in a sophisticated sequence, starting with appetizers, then Otsukuri (sashimi), simmered dishes, grilled dishes, fried dishes, and finally rice, soup, and dessert. This progression is designed to fully savor the story of each dish.
- 2. Enjoying the Marriage of Food and Local Sake
・Local Brews (Jizake): To complement the fresh vegetables, meat, and Nikko’s unique Yuba dishes, we highly recommend trying the local sake (Jizake) from Tochigi Prefecture. Enjoying the synergy between the cuisine and local sake leads to a deeper, more refined gastronomic experience.
・The Meal as an Event: Kaiseki is served at a deliberate, slow pace. This is intentional; it is designed to be an event in itself, allowing you to fully enjoy the artistry created by the chef.
- 3. Concluding Your Journey with a Traditional Japanese Breakfast
・Gentle Start to the Day: Ryokan breakfast usually consists of a traditional Japanese set meal (Wa-Teishoku), including grilled fish, egg dishes, miso soup, pickles, and vegetables. This light, healthy meal soothes the stomach and supports a comfortable start to your day of travel.
