Brucite from Sasaguri occurs as foliated or fibrous aggregates, associating with calcite and yellowish serpentine. H=2.5; S.G=2.475; &omega;=1.562, &epsilon;=1.581. Chemical analysis gives: SiO<sub>2</sub> 0.33, Al<sub>2</sub>O<sub>3</sub> 0.08, Fe<sub>2</sub>O<sub>3</sub> 1.69, MgO 64.81, MnO 1.10, H<sub>2</sub>O(-)0.39, H<sub>2</sub>O(+)31.38, total 99.78. X-ray powder data and D. T. A. curve are also given. The mineral seems to have been formed under hydrothermal condition.
