Uwajima City, where I live, is situated in the southwest of Shikoku and the primary industry, specifically oceanic aquaculture, is prosperous. The unique topography, surrounded with deep creeks which are characteristic of the Rias coast, as well as the blessed fishing environment due to a suitable change of water temperature, allows all year round cultivation. Therefore, the pearl cultivation in this specific area has the best of both quality and quantity within Japan and it is the main industry that represents Uwajima.
The history of Doi Pearl Co.,Ltd., began in 1957 when the founder, Nobunori Doi, my grandfather, started a seedling collection of Akoya oysters abalone used for pearl cultivation. For over 60 years, throughout the generations, manufacturing has always been our passion alongside the pearl industry which has been continuously going up and down. We also have been dedicated ourselves to our local community focusing on Uwajima as well as having continued our steps to treasure our “fate” with many people for a long period of time, including moving the business onto pearl cultivation, starting a division of processing and selling as well as starting a pearl cultivation experience tour, etc.
We will continuously provide manufacturing of a wide variety of MADE IN JAPAN and MADE IN UWAJIMA merchandise that highlight the pearls of Uwajima, lovingly nurtured over the generations along with our local community and which we are proud of to the world, and we will continually do our best to spread the charm of Uwajima to all people in order to have more individuals become fans of Uwajima.
