Otsuki Pearl boasts a wide lineup of products and skilled sorting and processing techniques.
Our level of quality is backed up by these skills. Many customers say,
“Otsuki Pearl’s products are different in quality” because of the detailed sorting by numerous people and the sentiments of all our employees,
who are always looking for the best pearls.
We feel responsible for providing those products and conveying those sentiments to our customers.

Our customers have placed their trust in us and continue to do business with us.
In order to not betray their expectations, we place the utmost importance on consistently supplying beautiful,
quality products and on our relationship with customers more than anything else.

Head Office

We do not sell door-to-door at our Head Office in Kobe.
Instead, we simply invite customers to come talk business with us.
This is to prevent scattering of our inventory and it allows customers to choose from a wide variety of products to meet their demands.

Tokyo Branch

We have a branch in Ginza, Tokyo, which is in central Japan. Unlike the format of business talks at our Head Office, the Tokyo branch orders products from the Head Office based on the customer’s demands, and our sales representatives visit the customer to show them the products in person.
