 Company profile


Our proud green tea manufacturing facilities are
right in a blanket of rich green.



Our green tea plantation is located in the Nissaka area where high-quality green tea is produced, blessed with most fertile soil and best climate in the Kakegawa city of Shizuoka prefecture boasting of its Japan’s No. 1 green tea yield. From the Edo era we have been supplying green tea rich in taste and flavor produced in the vast tea plantation on the cultivation land granted to our ancestors by Kazutoyo Yamanouchi, the lord of Kakegawa castle.




Picking tea leave, tea manufacturing and stocking is conducted in the highly efficient operation process. Especially, the “crude tea” or raw material of the natural leaf tea is vacuum-packed divided in 30kgs each to maintain its freshness and stored in the temperature of minus 10 degrees packed in corrugated cardboard boxes.

↑The finishing of the green tea is done in the highly clean and hygiene processes requiring no manual operation.
↑A foreign matter-removing device installed to eliminate impurities mixed in the green tea.




Very fussy about taste
It was back in 1955 when we changed to the present “deeply steamed tea” manufacturing method, and since then we have been devoting all our energies to supplying green tea that could be up to anyone’s satisfaction. Our present company president, Hiroaki Otsuka qualified to certify technical grade of green tea and our present company managing director, Yasuhiko Otsuka who won ninth place in the individual match of the 50th All Japan Green Tea Technical Examination Tournament, are pursuing together to develop further good-taste green tea. On the other hand, in order to supply green tea stabilized in quality, daily check of the finished green tea is being implemented.




Our company is shining with a number of honors.
With its spirit of placing a great value on the “natural taste” that has been succeeded to from generation to generation since the establishment of our company having steadily borne fruit, our company has won first place for six years in a row since 1999 in the Excellent Green Tea Fair held in Tokyo, the largest green tea consuming area in Japan, and in 2003 it gained the prize of the Governor of Shizuoka prefecture, the Japan’s largest green tea manufacturing area. And in the year of 2005, our company won the prize of the Japanese Minister of Agriculture, Forestry and Fisheries, the highest prize of the Tokyo Excellent Green Tea Fair.
