Chapter 7
Y15 8th of March: “Seto Nai Kai [the Inland Sea] is very beautiful and I crossed it by ferry. I ascended a steep, tall hill in Kagawa and visited the Kotohira shrine sitting on top of it.”
Y16 21st of March: “The Do¯ go hot spring in Ehime is one aim of my travel and when I arrived, I found many people having baths in the hot spring.” The Isaniha shrine in Do¯ go has twenty-two surviving sangaku. When visiting Do¯ go, Yamaguchi could have seen two of these tablets in the nearby Isaniha shrine. However, he makes no mention of them.
Plate 7.7. The Isaniha shrine today. The monkeys are not studying mathematics. They are admonishing tourists to “See no evil, hear no evil, speak no evil.” (Photo Fukagawa Hidetoshi.)
