Various types of sand for golf courses
[Sand for green areas of golf courses]
In recent years, various types of grass have been used for bentgrass in green areas of golf courses, and as a result, the number of golf courses offering high-quality putting has increased. As such, the average player is required to have good putting technique, and playing golf has become more enjoyable. 
In response to these tendencies, clients make detailed requests regarding things such as the production site, grain diameter, and composition of joint sand, which is used around bentgrass in green areas, in order to match the grass at each golf course. While listening to the opinions of green keepers from various golf courses, we produce sand for green areas, which matches clients' requirements to the fullest extent possible, in subdivided production processes in our factory. We are particularly committed to the production sites and quality of Aomori sand (produced in Rokkasho Village, Aomori Pref.) and Kashima sand (produced in Kamisu City, Ibaraki Pref.) that are suitable for bentgrass greens. We wash the sand with water, sift it, dry it, and classify it by using coarse, middle, and fine meshes. Then, we mix these sizes of sand to create sand with subdivided grain diameters and composition to provide sand products suitable for maintenance in each season.
[Bunker sand] 
In our factory, we produce bunker sand using Kashima sand. The bunker sand is somewhat gray-colored, but small stones with a diameter of 2mm or over are completely removed from the sand. In addition, if fine or ultrafine sand from the bunker sand is spread onto a green area, no damage is caused to the area. Moreover, water permeability and durability are maintained for a long period. Since the bunker sand is reasonably priced, it is strongly favored by our clients. 
There is a proverb, "white sand and green pine trees." Some clients have told us that for golf courses with many pine trees, bunker sand made from Kashima sand, which has a moderate color, is more suitable than vivid white sand, creating a more relaxed atmosphere.
