Today, Itoigawa can no longer legally be collected from this region and so the Japanese now simply graft cultivated Itoigawa foliage onto Junipers from other regions of Japan, such as Tohoku and Hokkaido Shimpaku from further north. For example, the tree featured to the right is a famous Tohoku Shimpaku grafted with Itoigawa Shimpaku foliage and aptly dubbed ‘Fujin’ or Wind God. So what is it that makes Itoigawa Shimpaku foliage so desirable? For starters, its fast growth habit allows for rapid development of padded branches. Itoigawa foliage is also more stout than other Juniper varieties and thus requires less frequent wire application and maintenance.
