Japanese officials were more focused on specifics than the British, and they approached the conference with two primary goals: to sign a naval treaty with Britain and the United States and to obtain official recognition of Japan's special interests in Manchuria and Mongolia. Japanese officials also brought other issues to the conference: a strong demand to remain in control of Yap, Siberia, and Tsingtao as well as more general concerns about the growing presence of American fleets in the Pacific.
