Onneto Yunotaki Falls investigation @Hokkaido
(Mar. 24-26, 2013)


The day after the graduation ceremony, we traveled to Hokkaido with Chihara-san and the members of Prof. Takahashi's group. The snow had not been removed for about 5km before the research site, so we traveled on snowshoes.
Onneto means "old swamp" in the Ainu language, but it was completely frozen over. After about an hour and a half, we finally arrived at the research site.
This is Yunotaki Falls. Manganese deposits have formed in the waterway. Because Yunotaki Falls is a natural monument, permission was obtained before the survey could be carried out. Prof. Bau, who worked to have it designated as a natural monument, also accompanied us on the survey, and we were able to hear many interesting stories from him. 
We returned to the lodging near the research site and had a meal. Afterwards, we immediately carried out microelectrode measurements. The measurements continued until late at night, which was tiring, but we were satisfied with the interesting results we obtained.
