Following our preceding investigations, we investigated Trichophytia capilliti of 13 primary schools (10,112 pupils), and of 7 junior high schools (2,077 pupils!, totaling 12,189 pupils of the Wakkanai area and the Okhotsk seacoast. By inspection it was found that the percentage of contraction of Trichophytia capilliti and facial was 28.1% in Wakkanai, 27.3% in the regions along the northern Okhotsk seacoast, and 24.9% in the central part of the same area, which are high above the 4.6% of Sapporo area the 9.5% of southern Hokkaido regions, and the 12.4% of regions of eastern Hokk-aido. It was closer to the 33.1% of Hidaka regions. Clinically, the percentage of contraction with Trichophytia capilliti was 0.755% of the primary school boys, 0.058% of the girls, and 0.096% of the boys of junior high schools with none of girls of the same. The percentage of Trichophytia faciae also of the boys of primary schools was 22.12%, girls of same was 8.84%, and junior high school boys showed a percentage of 17.47% with the girls at 6.11%. It was observed that the ages of contraction included most of those in the lower graded. Also, pertaining to sex, the boys showed an exceedingly larger number which was similar to the results of investigations made so far, of the 45 culture positive cases, the definite percentage of contraction in Wakkanai was 0.86%, 0.8% in the regions along the northern coast of the Okhotsk Sea, and 0.24% in the central part of the same, indicating an average of 0.63%. The percentage of junior high school students was 0.05%. From the 45 cases, strains were obtained. . The species were Microsporon sapporense, (23 strain) and Microsporon Japonicum Dohi et Kambayashi, 1921, (23 strains), and Bodinia Violacea Ota et Langeron (1923) (1 strain). It was noticed the from 2 cases of the said strain, it was possible to obtain culture of Microsporon Sapporense and Microsporon Japonicum at the same time. We have stated generically on the culture. And on mycological observation concerning Bodinia Violacea Ota. et Langeron. It was interesting to note that from the 309 strain obtained from Wakkanai, the second time, the center zone of the culture colony was of light yellowish-brown and cerebri form. Although it is considered to be difficult to culture Trichophytia faciei, we were able to obtain 1 strain each from Microsporon Sapporense and Microsporon Japonicum Dohi et Kambayashi 1921.
