Captain Nakamura was accompanied by Nobutarō Isugi, a retired Japanese army sergeant, a Mongolian and a Russian interpreter. Nakamura was travelling incognito, in civilian dress, and represented himself as an "agricultural expert". The party of four left Pokotu on the Chinese Eastern Railway about the middle of June, their immediate destination being Taonan. Nakamura made stops along the Chinese Eastern Railway, at Manchuli, Tsitsihar, Angangehi, and Hailar taking notes.
