About Us

Since 1920

KAJITA's predecessor, Kajita Shoten, was founded in 1920 by the first-generation founder, Kyujiro Kajita. Over the past century, we have remained steadfast in our belief in the timeless value of gemstones, continually creating jewellery that reflects the spirit of each era. Today, under the leadership of the fourth-generation president, Kengo Kajita, we manage every aspect of our business in-house— from gemstone sourcing and design to quality control. Our activities encompass wholesale distribution to department stores and retailers across Japan, retail sales at our Omotesando salon in Tokyo, as well as retail operations in Singapore and Taiwan.

From Hand to Hand

At the heart of KAJITA's jewellery is our commitment to craftsmanship, where "human hands matter."In gemstone sourcing, we carefully select each stone with a discerning, professional eye, ensuring only the finest quality. In design, we engage deeply with each gemstone to bring out its inherent beauty while prioritizing exceptional comfort and wearability. In retail, we take a personalized approach, offering tailored recommendations that resonate with each customer’s unique needs and preferences. Given the enduring nature of jewellery as an heirloom that transcends generations, we strive to ensure that every piece— and every experience— reflects the human touch and care that define our brand.

KAJITA Quality

KAJITA’s aesthetic vision is the culmination of over 100 years of accumulated expertise, which is evident in our creations today. We select gemstones with rich color and clarity, where superior cuts reveal the stone's natural brilliance, and inclusions are minimized to the utmost degree. Our designs are crafted to accentuate each stone’s unique charm. Manufacturing is entrusted to trusted workshops in Tokyo, where we collaborate with skilled artisans to ensure impeccable craftsmanship. Grounded in a history of exceptional techniques and knowledge, we continue to seek out higher standards of quality in every piece we create.

Since 1920

KAJITA's predecessor, KAJITA SHOTEN, was founded by Kyujiro Kajita I in 1920. For more than 100 years since then, we have continued to create jewelry appropriate for the times, believing in the enduring value of gemstones. Currently, under the leadership of Kengo Kajita, our fourth president, we are engaged in wholesale sales to department stores and retailers throughout Japan, retail sales in Japan centering on our salon in Omotesando, and retail sales overseas in Singapore, while conducting our own jewelry purchasing, design, and quality control.

From Hand to Hand

At the core of KAJITA's jewelry is that it is handled with care by human hands.
When purchasing gemstones, we carefully assess the quality of each gemstone with a professional eye and carefully select and purchase them. In designing jewelry, we work diligently with the gemstones to maximize their attractiveness and uncompromisingly focus on comfort. In sales, we must make proposals that are in tune with the feelings of each and every customer. We hope that through our products and services, our customers will feel the presence of human hands, which are surely rich in blood, as jewelry is an item that will be used for generations to come.

KAJITA Quality

Our aesthetic sense has been accumulated over more than 100 years of history. It is certainly reflected in our creations today. Gemstones are selected for their inherently attractive colors, which are brought out by excellent cutting. Inclusions are carefully selected to be as inconspicuous as possible. We seek to create designs that bring out the charm of the gemstones. We outsource the manufacturing to a trusted factory in Tokyo, where we work closely with skilled craftsmen. We continue to search for higher quality based on the techniques and knowledge backed by our history.

CEO Message

Crafted with Integrity, Delivered with Purpose

Since the founding of our predecessor, Kajita Kyujiro Shoten, in Asakusa in 1920, we are deeply grateful that over the past century, our business has continued to thrive.

From our early years manufacturing and exporting smoking accessories and small goods, we have gradually evolved into the jewelry maker we are today, with Kajita Co., Ltd. now recognized as a prominent brand for coloured gemstone jewellery—KAJITA. While the products we offer and the needs of our customers have changed over time, the core values and DNA of our company have remained steadfast.

At the heart of this is our commitment to:
- Understanding our customers’ hearts and delivering jewelry that moves them.
- Providing not only exceptional quality but also a level of service that touches people’s hearts.

As a jewellery maker, crafting fine pieces from the precious natural resources of gemstones, we are committed to addressing the broader social issues that impact the environment and human connections. We strive to create a sustainable cycle of joy that transcends individual actions, fostering a positive impact on both society and the world around us.

With these values in mind, our mission is clear: to create with integrity, to bridge the intentions of the creator, the seller, and the wearer, and to deliver jewellery that tells a meaningful story. Every member of our team is dedicated to working thoughtfully and diligently to fulfill this mission.
