The Chargé in Japan (Caffery) to the Secretary of State
[Received 9:45 p.m.]
13. My 10, January 12, 3 p.m. War Office has notified me informally this evening that the Japanese authorities consent to landing at Bettobu and will be prepared to receive advance officer here in Tokyo to discuss details. Navy Department is disposed to send war vessel to Kurile Islands for “protection purposes” during flight. Naval hydrographic bureau offers suggestion that flight should take place between latter part of April and middle of May on account of floating ice before that period and dense fogs thereafter.
