YJF - Yamanashi Jewellery Fair

The Yamanashi Jewellery Fair as a Landmark Event for the Global Jewelry Industry

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. From the very first moments, the fair reflects the unique spirit of a region that has shaped Japanese jewelry craftsmanship for centuries. More than just an exhibition, the YJF has become a meaningful meeting point where tradition, innovation, and international collaboration naturally come together.

Yamanashi is widely regarded as the heart of Japan’s jewelry manufacturing, and the fair captures this identity in a refined and professional setting. Industry professionals visiting Kōfu are immersed in an environment where diamond cutting, gemstone processing, and jewelry production are not only technical skills but cultural expressions passed down through generations. This deep connection to craftsmanship gives the Yamanashi Jewellery Fair a character that feels authentic rather than purely commercial.

Organized by Informa Markets in close cooperation with the Yamanashi Jewellery Association, the fair has developed into a trusted platform for dialogue within the jewelry world. It attracts manufacturers, designers, retailers, and experts who value quality, precision, and long-term partnerships over mass production or fast trends.

The Role of the Yamanashi Jewellery Fair in Connecting Professionals

One of the most important strengths of the Yamanashi Jewellery Fair lies in its ability to bring together different segments of the jewelry industry in a focused and respectful atmosphere. Unlike large-scale consumer exhibitions, the YJF is designed specifically for professionals who seek meaningful exchanges and carefully curated products.

Participants come not only to present collections, but also to build relationships and share knowledge. The fair encourages open conversations about craftsmanship, market direction, and evolving design philosophies. This professional openness is one of the reasons the event continues to grow in importance with each edition.

The exhibition showcases a wide spectrum of materials and finished pieces, allowing visitors to explore both classic and contemporary approaches to jewelry creation. Among the highlights are:

High-quality diamonds known for precise cutting

Carefully processed gemstones, including quartz and sapphire

Elegant pearl jewelry reflecting refined aesthetics

Jewelry crafted from gold, silver, and platinum

These elements are presented in a way that emphasizes quality and origin rather than volume, reinforcing the fair’s reputation as a space for thoughtful discovery.

Kōfu as the Historical and Cultural Foundation of the Fair

The choice of Kōfu as the host city is far from accidental. For centuries, the city has been a major center of gemstone processing in Japan, with roots reaching back to the Edo period. This historical background shapes the identity of the Yamanashi Jewellery Fair and adds depth to the experience for international visitors.

Kōfu is home to numerous workshops and companies that are internationally respected for their precision and innovative spirit. Walking through the city, one can sense how tradition and modern technology coexist naturally. This atmosphere makes the fair feel like an extension of the city itself rather than an isolated event.

Another advantage of Kōfu is its accessibility. Located just 90 minutes from Tokyo, it offers convenient access while allowing visitors to step away from the intensity of the capital. This balance between connection and calm creates ideal conditions for focused business discussions and creative inspiration.

Educational Value and Industry Insight at the YJF

Beyond the exhibition floor, the Yamanashi Jewellery Fair offers a strong educational component. Expert lectures, seminars, and networking events are carefully integrated into the program, providing participants with deeper insights into industry movements and market trends.

These sessions are not designed as formal presentations alone, but as opportunities for dialogue. Experienced professionals and emerging designers alike benefit from the exchange of perspectives, making the fair relevant across different career stages.

Key themes explored during the event often include:

The evolution of jewelry design in a global context

The balance between tradition and innovation

Long-term value creation through craftsmanship

Building sustainable international partnerships

This thoughtful approach reinforces the YJF’s role not only as a marketplace, but also as a space for learning and reflection.

Strengthening Yamanashi’s Position as a Global Jewelry Hub

The Yamanashi Jewellery Fair plays a vital role in positioning the region as a global jewelry hub. By welcoming international buyers, investors, and designers, the fair helps local companies present their work to a wider audience while maintaining their distinctive identity.

At the same time, international participants gain rare access to Japanese craftsmanship at its source. This mutual exchange strengthens trust and encourages long-term collaboration rather than short-term transactions.

With each new edition, the fair attracts a broader range of professionals, from emerging talents to established market leaders. Its unique concept combining high-quality exhibitions with exclusive networking continues to resonate within the global jewelry industry.

The YJF stands as a reminder that true value in jewelry lies not only in materials, but in the stories, skills, and human connections behind every piece.
