Discovering valuable jewels lying dormant in urban mines.
The mission of Iroishi Bank is to discern the value of difficult-to-appraise second-hand jewels that are hidden away in “urban mines,” and then to purchase those jewels at a fair price. We continue to discover valuable jewels scattered throughout Japan.
We purchase second-hand jewels from “urban mines” across Japan.
Bases established in major cities
Extensive support for customers throughout Japan
As of May 2023, Iroishi Bank has bases in four cities: Tokyo, Osaka, Fukuoka, and Nagoya. This allows us to maintain close communication with customers in each region and respond quickly to their needs. Going forward, we plan to open new bases and hire even more buyers in order to support even more customers.
Unique evaluation system to improve the speed and quality of customer service
Iroishi Bank has developed a unique evaluation system to improve the performance of our members. In addition to numerical results such as purchase price, evaluation criteria also include behavioral indicators such as the number of visits made to customers. This allows us to continue improving the speed and quality of our customer response.
Utilizing our unique capabilities to acquire advanced purchasing know-how in a short period of time
In the jewelry industry, it is said to take ten years to acquire the know-how necessary to determine the value of jewels and purchase them at fair prices. However, Kishun was able to shorten this period by using our own Appraisal Institute, in-house certification system, in-house training held at external facilities, team-based purchasing, and accumulated data. We will continue to provide value by acquiring advanced know-how at a speed surpassing other companies.
