The current rate is the early booking discount rate. The 2025 rate will be decided in early February. Flash photography is prohibited when watching fireflies. The Alps, forests and lakes. A thrill of love and indigo. Watch the fireflies at Lake Aokiko by boat. The forest on the cape jutting out into Lake Aokiko turns into a huge summer Christmas tree. The faint, beautiful glow of the stars shining down from tens of thousands of light years away and the small love light of the fireflies compete in a big picture story on the mirror-like heart-shaped lake "Lake Aokiko". We watch fireflies on the boat at Lake Aokiko. The trees over hanging the lake in summer provide a Christmas tree like setting. On clear nights you can enjoy star lights and fireflies both at the same time. With some imagination it looks like a Meteor Shower, the contest of the light between fireflies and stars. Booking by phone is 3,600 yen per person.

There is a legend that if you see the Strawberry Moon, you will be able to marry the person you love and be happy! The full moon around the summer solstice is reddish in color compared to full moons in other seasons, and American Indians called it the "Strawberry Moon" in English. The original season for strawberries is early summer. The Strawberry Moon in 2025 is June 11th. Board the Voyageur Canoe and enjoy a walk on the lake surface under the stars (at night) while eating delicious Shinano Omachi strawberry sweets (sweets made with strawberry ingredients may not be available).

When the stars look beautiful at night at home or on a trip, we will explain it in an easy-to-understand manner so that you can remember the explanation of the astronomy guide.
