    Food Additives

    Today, problems in the food industry occur under the circumstances of diversified needs of consumers. We work to solve those problems so that customers engaged in cooking can provide safer, more secure, and better foods. Our product line includes food improvers like the amazingly long-selling rice improver Suihan Miola.


  • Agricultural Chemicals

    As a comprehensive manufacturer of rodenticide, we produce and sell chemical products suitable for various purposes domestically and overseas. Based on the concept that the technology for a formula is most important in order to improve the eating-inducing effect, we devised a mix formula to produce and supply a high quality, effective rat poison. These days, there is great demand for rodenticides that are less harmful to the natural environment and non-target animals, and thus our Yasodion (diphacinone) is valued highly. In addition to supplying the chemical product, we also provide related information on methods of application of the rodenticide suitable for target crops and the environment in order to support users.
