The most prized Koh-Boku is Jin-koh (Agarwood / Aloeswood).Through forces of nature, a tree falls in a misty tropical forest.In a unique, magical process that can take hundreds of years, resins within the wood solidify, making it very dense and concentrating its exquisite fragrance.It is believed that a pure stream of life energy is being condensed during its formation.It benefits us -bringing clarity and peace of mind. Agarwood is an Appendix II item of CITES (the Convention of International Trade of Endangered Species), for which Shoyeido has been fully compliant. While there are no restrictions for Shoyeido to distribute agarwood products within Japan, an export permit issued by METI (the Ministry of Economy, Trade and Industry) is required when agarwood items are exported from Japan. Please refer to the regulations established by your domestic government when applicable. Shoyeido works with and respects the natural environment.All of our ingredients and woods are ecologically gathered and harvested.
