Kouzushima, the Tokyo island for enjoying outdoor activities | Part 3

As Kouzushima is a volcanic island, you can see unusual looking lava rocks along the seashore or on the mountains. In fact, Kouzushima is famous for production of Obsidian since ancient time (30,000-5,000 years ago), Obsidian is used as a material to create knives or tips of arrows that have been excavated at archaeological sites in the mainland of Japan, more than 200km or even 400km away from Kouzushima Island. It is mysterious how ancient people managed to go to Kouzushima and bring back the obsidian. In the first place, how they knew that they could obtain obsidian in that far island!?

The black stones in the photo below are obsidians. There is an atelier called Youseki Kobo, offering group lessons to create charms with obsidians. Creating the charms might be more fun than you expect as it involves some struggling to handle tiny beads. You might find yourself saying “Oops!” or “Doh!” or "Yes!" while you are creating. Afterwards, the moment comes when you find yourself showing your work proudly with a smile. The charms you create will be a good souvenir from Kouzushima Island. The lesson is one-hour long and the fee is 1,500 Yen per person. (Prior booking is required).
