September 1895, Saneyuki visited Shiki in Matsuyama as a warship, "Tsukushi",returned to Kure. At that time, Shiki had been boarding with Kinnosuke Natsume who was appointed as a Junior high school English teacher in Matsuyama. On his way home, Saneyuki asked Ritsu about Shiki's condition. Ritsu bravely answered she will not fail to cure his disease. June 1875, a topic of study abroad was brought up among young naval officers. Saneyuki dared to go to the United States, a developing country under Europe. Saneyuki's best friend, Takeo Hirose, expected a future battle between Russia and Japan, and decides to go to Russia. Saneyuki visits Shiki before he leaves and Shiki tells that he will compose a Haiku, risking his life. While studying in the U.S., Saneyuki asked a world tactician, Alfred Mahan, for guidance and had an opportunity to go as a military officer to observe military operations. The report has been said to excel above all others in Japanese naval history.
