Content The author Noritaka TSUNETO was Japan's first Doctor of Agriculture after the Meiji Restoration. He conducted surveys all over Japan to investigate the distribution of phosphate ores as a raw material for fertilizer. In Okinawa, he surveyed the Senkaku Islands, Hateruma Island and others, and reported the results in "Minami Nihon no Fugen (Rich Resources of South Japan)".
This document is his memoir about his phosphate ores surveys. In this document, it recorded that when, having received a commission from Okinawa Prefecture in 1907, a party led by him surveyed phosphor resources on the Minami-Kojima Island, an uninhabited island in the Senkaku Islands of Okinawa Prefecture, some members drunk water containing poison, eluted arsenous acid for making stuffed sea birds on Minami-Kojima Island, and fell unconscious, and also recorded situation of visit by family members to go to meet migrant workers in the Senkaku Islands.
