Corporate
Profile

Our company, founded in 1916, is the pioneer in Japan to produce chipper shredders and tree crushers. We have both history and a proven track record in the manufacture and sale of agricultural pumps and tree crushers.

Our company was the first company invited to Yamagata Prefecture from Ehime Prefecture in 1939, and we now mainly make tree crushers.
Karui Co. Ltd. was the first manufacturer to produce tree crushers in Japan, and our manufacturing, processing, assembly, and coating processes are firmly integrated. 
Our products are used by a wide range of users, including those in the livestock and landscaping industries. 
Karui has gradually improved the crushers’ performance and the operating safety and has incorporated user feedback into its current products. 
For the first time, we installed a blower assembly that is attached to a snow blower onto a crusher seven years ago to facilitate the transportation of chips.
The crushed chips are mainly used as fertilizers for rice paddies and fields.  Tree crushers, which reduce waste and improve the soil quality by turning waste into a resource such as fertilizer, are outstanding products from an ecological point of view.
