Genna Koukaiki - Genna Koukaiki

Japanese: 元和航海記 - げんなこうかいき

Also known as the Genna Koukaisho. 1 volume. Completed in 1618 by Ikeda Koun (date of birth and death unknown). Koun was from Nagasaki, learned navigation from Portuguese red seal ship trader Manuel Goncalves, and the two traveled to Luzon together, writing this book based on their experiences. It deals with latitude measurement methods, astronomical observation instruments, mileage tables, ocean depth measurement, meteorological observation, etc. However, the contents are largely based on Anjinmondo by the contemporary geographer Manuel de Figueredo (Portuguese).

Japanese:

元和航海書とも。１巻。池田好運（生没年未詳）が1618年に完成。好運は長崎の人で，ポルトガル人の朱印船貿易家マヌエル・ゴンサルベスに航海術を学び，２人でルソンに渡航，その経験に基づき本書を書いたという。緯度測定法，天文観測器械，里程対照表，海深測定，気象観測等を扱う。しかし，内容は同時代の地理学者マヌエル・デ・フィゲレード（ポルトガル人）の《按針問答》によるところが大きい。
