Yoshimuraite is a complex barium manganese titanium silicate phosphate; it is a member of the bafertisite group, itself part of the seidozerite supergroup (Sokolova & Cámara, 2017). The mineral name honors Professor Toyofumi Yoshimura (1905-1990), mineralogist at Kyushu University, who specialized in manganese deposits (Watanabe et al., 1961).

Yoshimuraite forms brown grains to 2 mm in an altered mass of rhodonite and quartz with minor dark green katophorite. Somewhat friable. From the collection of E.R. Laskowski (1949-2020), a mining engineer who retired to Tucson, Arizona. A label from Mineralogical Research Company also accompanies the specimen.
