Obsidian Strap Making On Kozushima Island

Create your own strap with polished obsidian in Kozushima, an island part of Tokyo Prefecture. Your strap can be a keychain or a phone strap which you can take home as a souvenir, a gift or a good luck charm made from rare obsidian.

In this activity, you will be making a strap using obsidian on Kozushima, an island located off the coast of Japan and is part of Tokyo Prefecture. Obsidian is a type of stone that forms when lava cools rapidly. Seen as a protection stone, obsidian is believed to ward off negative energy and rejuvenate hope in life, making it perfect souvenir or gift.

The stone is rare in Japan and the ones you’ll be using for this activity are collected by local divers at Onbase Island, a neighboring uninhabited island. Obsidian production in Kozushima has a long history dating back to the Heian period (794–1185) when it was the primary export of the island.

The strap making steps are very easy to follow. Start by choosing from an array of polished obsidians and connect the obsidian over the strings.Create and design in whichever way or style you want! The strap can be used as a key chain or a phone strap.
