Isetan Department Store is a major landmark in Shinjuku and known as one of the prime department stores in Japan (if not Asia) in high fashion. With that said, I look forward to the success of TILLA-EARTH, a jewelry brand from Ishigakijima. Shizuka Taira, the owner of the store, will sell his jewelry for a limited time from June 27th ~ July 17th on the first floor of Isetan. He will also set a booth at the well established Ginza Mitsukoshi (July 18th ~31st).
There are many other Okinawan jewelry brands, many simple and charming. Here’s a list of some of them (the website may not have English translations):
Grand Blue (known for rings with natural star sand in them and minsa motifs)
Ruca (jewelry using coral reefs)
cicafu (accessory inspired by Native American jewelry)
Grain (furniture design, but they sell rings made of Yakushima cedar)
