Experience Serene Stargazing in Karuizawa
The clear air provided by Karuizawa's 1,000-meter-high plateau and the high clear-sky rate in winter create the perfect environment for astronomical observation. Here, you can spend an evening far removed from the hustle and bustle of daily life. We welcome you warmly with cushions and blankets provided on the benches. Enjoy a time where your mind and body can be fully reset, sharing this peaceful night with your loved ones.

A Warm Drink to Color Your Unforgettable Moment
Please choose between spice-infused hot wine to set the stage for an adult evening, or heart-warming hot cocoa to soothe your mind and body. (Guests who are driving or children must select the hot cocoa.) The warm aroma spreading with the steam gently wraps around your chilled body, making your stargazing experience truly memorable. We will confirm your drink preference when you make your reservation.

"Constellation Card": Carrying the Night Sky's Story Home
As a keepsake of your tour, we will present you with a simple Constellation Card designed with the winter night sky. This palm-sized card is the perfect size to softly hold the memory of this evening's experience. Why not take your time later to write down the constellation myths you learned from the guide, or a message for a loved one that came to mind? Take this item home with you as a piece of your Karuizawa starry sky memory.
