Ando-soils are distributed widely in Japan. Previous studies showed black plant particles included in Ando-soils that are considered as charcoal particles. Our studies confirmed that black plant particles in Ando-soils distributed around Lake Biwa are charcoal particles by observation of reflectance microscopy, reflectance measurements, and H/C ratio analysis. These black plant particles shine white under reflectance microscopy, and have higher reflectance and lower H/C ratios similar to modern charcoal. These results prove that charcoal particles are included in Ando-soils in this area. The values of reflectance and H/C ratio suggest that charcoal particles were probably the result of forest fires or grass fires. The charcoal concentration increases from upper AT Volcanic glass-rich stratum to K-Ah Volcanic glass-rich stratum. This tendency is almost consistent with that of charcoal concentrations in Lake Biwa sediments. Therefore, some charcoal particles in Lake Biwa sediments are probably derived from fires in Ando-soils distributed in areas around Lake Biwa.
