Since 1977, Hokkaido Prefecture, Japan
Making the best use of traditional Japanese raw materials for their products, Rinnesha takes responsibility for the entire cycle of production, from cultivation to consumption.
Based in Takigami-cho, Hokkaido, Rinnesha works with local and Chinese farmers to preserve the traditional raw material of the pyrethrum plant, which was once produced in abundance but is now almost extinct. The flowers and stems of the pyrethrum are milled and used as the main ingredient in their Kikuhana Senkou incense, the smoke from which acts as a natural insect repellent. This method of insect repellent had been used since ancient times, but had been all but forgotten with the invention of synthetic chemical pesticides.
In 1998 the Rinnesha company developed the Kikuhana Senkou incense as a solution to chemical sensitivities experienced from using domestic insecticides. This all-natural product was successfully resurrected from the past!
Today, Rinnesha works closely with pyrethrum farms in Hokkaido and China to make sure the plants are grown without chemicals or pesticides, ensuring that the final product remains safe, reliable, and produced in a consistent environment.
