Yamanashi Jewellery Fair (YJF) Kofu

The Yamanashi Jewellery Fair (YJF) is an exclusive trade fair for the jewelry industry, held annually in Kōfu, the capital of Japan’s Yamanashi Prefecture. This region is the heart of Japan’s jewelry manufacturing, renowned for its exceptional diamond cutting, gemstone processing, and jewelry production. The YJF serves as a key meeting point for both national and international industry professionals, providing a unique platform to explore the latest trends, innovations, and exclusive jewelry pieces.

The fair is organized by Informa Markets, one of the world’s leading trade fair organizers, known for hosting prestigious events such as Jewellery & Gem World Hong Kong. In collaboration with the Yamanashi Jewellery Association, the YJF creates an exceptional opportunity for manufacturers, retailers, designers, and experts to showcase their products, establish business connections, and exchange insights on industry developments.

At the heart of the fair are high-quality diamonds, gemstones, pearls, and jewelry crafted from gold, silver, and platinum. Visitors can discover exclusive collections, innovative designs, and exquisite raw materials. The exhibition is complemented by expert lectures, seminars, and networking events, offering in-depth insights into market trends and industry movements.

A key highlight of the YJF is its host city, Kōfu, which has long been recognized as a major center of Japanese jewelry craftsmanship. The city is home to numerous renowned workshops and companies internationally respected for their precision and innovation. The fair plays a vital role in further establishing Yamanashi as a global jewelry hub and strengthening collaboration between Japanese and international industry players.

Kōfu was strategically chosen as the venue due to its accessibility—it is just 90 minutes from Tokyo, making it easily reachable for both domestic and international visitors.
