GreetingPresident’s Message

Tea. It is a traditional food deeply ingrained in the lives of the Japanese and an excellent health product. At Ryufu Mizuno Shoten, since our establishment, we have been manufacturing and selling tea products such as tea bags with the motto of “more delicious,” “safely,” and “more conveniently.” We also leverage our facilities and experience to undertake contract manufacturing in the filling and packaging processes for many food manufacturers. In recent years, with the globalization of the world, consumer needs such as “more delicious, safer, environmentally friendly, and affordable” have been increasing. To meet these needs, we launched a new HACCP-compliant factory in 2002, leveraging our ideas and expertise gained over many years. Looking ahead to the increasingly challenging market conditions, we aim to differentiate our product manufacturing and actively engage in development with this production base as a backdrop. In 2012, we established a sales company in Malaysia. We aspire to continue providing innovative proposals for the diversified global market in the future. We sincerely request further guidance and encouragement from our customers.
