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.
