What is STAR JEWELRY?

STAR JEWELRY is one of Japan's longest-established jewellery brands. Founded in 1946 by Saburo Nagai, it opened a shop with its own workshop of skilled craftspeople in the Motomachi district of Yokohama, and is known for well-crafted pieces with playful, design-forward styling.

History

In the 1960s the brand popularised stacking several bangles together and was among the first to offer a wide range of pierced earrings in Japan. Hit designs followed from the 1970s to the 1990s, including a clock-motif ring and the initial marriage ring. Key later milestones include:

• 2004: the Motomachi flagship reopened as STAR JEWELRY THE SHOP and MUSEUM
• 2006: a flagship at Omotesando Hills in Tokyo and the launch of SJX, a men's and unisex line
• 2011: launch of the younger line STAR JEWELRY Girl
• 2019: limited-edition jewellery for Tokyo Disney Resort
