As the captain of the ship Shinsho-maru, Kōdayū set sail for Yedo in 1782. The ship was caught in a storm around Enshū and was blown off course. After drifting for seven months, one man died. Just after the man died, they found and landed on the island Amchitka where Russians and Aleut people lived. The crew witnessed the Aleuts' uprising in 1784. After the Russian ship which came to pick them up sank just in front of Kodayu's people and Russians, the 25 Russians and 9 Kōdayū's people escaped from the island by building a new ship of driftwood with sails made of otter skins. They sailed for one and a half months. Russian officials in Kamchatka at first could not believe they had sailed from Amchitka to Kamchatka in a "hand-made boat". At Kamchatka, Kōdayū met Barthélemy de Lesseps, a French diplomat. Lesseps wrote about the Japanese castaways and the leader Kōdayū in his book, Journal historique du voyage de M. de Lessepspublished in 1790. According to Lesseps, The crew had special feeling of attachment and respect with Kōdayū. He also showed his attachment as much as they did to him, and he always paid attention if they had any frustrating matters as possible as he could. Kōdayū did not hide what he thought and his Russian had a strong accent and he spoke very fast so sometimes Lesseps could not understand.. He wore Japanese clothes, which did not cover his throat, even when it was freezing cold, despite Russian people's recommendation that he should have covered his throat. A captain in Kamchatka, possibly by the name Khotkevich, led Kōdayū's people to Okhotsk. Kodayu's people temporarily stayed in Yakutsk. In Irkutsk, Captain Khotkevich introduced Kōdayū's people to Kirill Laxman. Kōdayū's people had assistance by others, including Kirill Laxman, in Irkutsk. Kōdayū then left for Saint Petersburg in order to accompany Kirill to ask to be returned home in 1791. By the instrumental help of Kiril, Kodayu was granted an audience with Catherine the Great in Tsarskoye Selo and Kodayu's people were permitted to return home in the same year.
