Kiryuzuna is a kind of volcanic sand produced in Japan, and contains a large amount of Fe2O3 (iron oxide) in hard rock sand. Used for planting orchids, deciduous plants, etc. This medium has good permeability, water storage, flowability and drainage. Suitable for plants such as bonsai and alpine flowers. Japan's horticultural cultivation medium resources are very rich, especially volcanic lava. Due to frequent volcanic activity, Japan enjoys abundant volcanic resources. Volcanic ash, volcanic rocks and pumice left over from volcanic eruptions in ancient times are piled up near volcanoes. Using this unique resource, Japan has developed a rich horticultural cultivation medium product, and the red jade soil and the deer soil cultivation medium are two representative ones. In addition, there are Kiryu sand, sunstone and physalis.

In Japan, such media products are used alone or mixed with other media for potted plants, such as peat, coco, bark, etc., and are widely used in horticultural production. Japan's horticultural cultivation mixed medium, the proportion of inorganic minerals mixed is much higher than the proportion of peat. Compared with many other countries, especially Europe and the United States, peat is used as the main cultivation medium. Japan uses such products as the main cultivation medium, which has obvious advantages. The application practice in Japan for many years proves that these products are also good soil improvement materials, which can comprehensively improve the soil condition and effectively promote plant growth.
