Izu Islands
"Stachyurus praecox" var. "matsuzakii" is native to the southern part of Japan, and is mainly grown around both the Izu Islands and the Tōkai region. It was first discovered on Hachijō-jima island (八丈島), one of the Izu Islands, hence the name "Hachijō-kibushi" (ハチジョウキブシ) in Japanese, where "kibushi" refers to "Stachyurus praecox". It is also found near a volcano on Miyake-jima island.
