【History of Hino-Seiyaku】

鳥居峠遙拝所一心行者像 It is said that the history of “Hyakuso” began at the end of the Edo period, when a mountain ascetic who received the message from Ontake daigongen (great incarnation of the Ontake spirit), which was enshrined at Kiso Ontakesan, taught the villagers to decoct the inner barks of Phellodendron that grew naturally at the foot of Ontakesan to make medicine. It was spread and manufactured throughout the northern part of 11 post stations on Nakasendo in Kiso, Narai to Kiso Fukushima, Mitake, and Otaki as house medicines. Hinoya was an inn at Yabuhara juku on Nakasendo in the Edo period and was selling Hyakuso to the believers of climbing Ontakesan and travelers. Its roots can be traced on the stone monument placed in the remote worshipping shrine on Torii Mountain Pass in Yabuhara.

 In 1947, the 11th generation of Hinoya, Bunpei Hino, founded “Hino-Seiyaku Partnership Corporation”, placed the head office in Yabuhara, Kiso-mura, and officially started manufacturing Hyakuso, Hyakusogan, and Kiogan. In March 1967, its name was changed to Hino-Seiyaku Corporation, which has been kept till today.


昔の薬袋 The name “Hyakuso” derives from the historical event in China that “Shennong licked Hyakuso to check its efficacy”, “Effective for 100 (hyaku) diseases”, or “Effective as if 100 herbal medicines are combined”. Tracing back its history of blending in with the history and climate of Kiso and gaining trust from many people, there were efforts of numerous pioneers. Reflecting the tradition, Hino-Seiyaku intends to pursue our studies to bring out even more beneficial effects of “Hyakuso” (Phellodendron).
