Continuing their flight around the world at the equator, Amelia Earhart and her navigator Fred J. Noonan, on July 2, took off in their Lockheed Electra from Lae, New Guinea. They were headed for Howland Island, a dot two feet above sea level in the Pacific Ocean some 2,550 miles away. The U.S. Coast Guard cutter Itasca was stationed just offshore the island to provide radio navigation and communication support to Earhart. The cutter was in contact with the Earhart plane after it departed New Guinea and intermittently thereafter. Radio reception was poor, but at 6:14 am July 2 the plane reported its position as 200 miles away from Howland. Earhart contacted the Itasca at 7:42am indicating “We must be on you, but we cannot see you. Fuel is running low. Been unable to reach you by radio. We are flying at 1,000 feet.”
The ship tried to reply, but the plane seemed not to hear. Just before 8:00 a.m. the plane radioed they were circling and requested bearings. Earhart and Noonan reported they had received the cutter’s signals, but were unable to obtain a minimum for a bearing. At 8:43 a.m. the plane reported being on line 157-337 and running north and south with no reference point given. It was the last Itasca heard from Earhart and Noonan. With no sign of the plane, it was assumed it had gone down. Itasca got under way at full speed to commence a search. 
The news of the disappearance appeared in the media throughout the world. Both the New York Times and the Washington Post on July 3 and 4 carried several stories about Earhart and Noonan being missing.
Upon hearing the news, undoubtedly the Roosevelts were most concerned. The First Lady, Eleanor and Earhart were close friends, and the aviatrix was a frequent visitor to the White House. Likewise President Franklin D. Roosevelt was on good terms with Earhart. In November 1936 she wrote him a lengthy letter explaining her plans for an around the world flight, as she had previously mentioned to him and the First Lady, and asked f or assistance from the Navy Department. The President annotated the letter “Do what we can and contact Mr. Putnam” [Amelia’s husband].
On the night of July 3 President Roosevelt was kept advised of developments in the search for Earhart through an open line from Washington, D.C. to Hyde Park, New York. He was advised that the Navy was doing all in its power to locate Earhart and Noonan. He also received information from the Coast Guard. The White House asked The Washington Post to provide any news it had to the White House so that it could be passed on to the President. 
Prince Fumimaro Konoe, who had become Japanese Prime Minister on June 4, 1937, and K?ki Hirota, who had become Foreign Minister in the Konoe Cabinet, had served as Prime Minister (March 1936-February 1937), undoubtedly became aware of Earhart’s disappearance and most likely they were the persons that gave the approval to contact the American Government regarding providing assistance in the search for Earhart. This could have been out of a humanitarian concern and the desire to remain on friendly terms with the United States at a time when there were increasing American concerns regarding Japanese activities in China. The Japanese leaders may have also been concerned about an American search possibly extending to the west, to the Marshall Islands, some 900 miles from Howland Island. These islands and others of the Japanese Mandate Islands had become “closed territory,” with entry by Westerners restricted, when Japan withdrew from the League of Nations in 1935. In any event, a telegram was sent from Tokyo to the Japanese Embassy in Washington D.C., offering Japanese assistance in the search.
On July 5, the Second Secretary of the Japanese Embassy, Tsuneo Hayama, telephoned Joseph W. Ballantine of the Division of Far Eastern Affairs of the Department of State and informed him that the Japanese Embassy had received an urgent telegram from Tokyo asking that inquiry be made of the United States Government whether the Japanese Government could be of assistance in connection with the search for Amelia Earhart, in view of the fact that Japan had radio stations and warships in the Marshall Islands. Ballantine expressed his appreciation of the kind offer of the Japanese Government and said that he would refer it at once to the authorities of the American Government. Ballantine got into touch with Stanley K. Hornbeck, Chief of the Division of Far Eastern Affairs, who communicated with Admiral William D. Leahy, Chief of Naval Operations. Ballantine, after talking with Hornbeck about his conversation with Leahy, called Hayama the reply of Admiral Leahy. Ballantine told Hayama that the Navy had received a faint message which offered a clue that Earhart’s plane might be down at a spot about 200 miles north of Howland Island, that the U.S.S. Lexington was then on its way to the spot from the Pacific Coast, and the U.S.S. Colorado from Honolulu, but that as the spot in question was some days sailing distant. If the Japanese Government had any vessels which could reach the spot earlier any assistance they could give would be appreciated. Ballantine told Hayama that the search was being directed by the Naval Commandant [of the 14th Naval District] at Honolulu, and suggested that the Japanese Navy get into touch with the Commandant for latest developments and in regard to arrangements for cooperation. Hayama responded that the Embassy would telegraph Tokyo immediately.
The Associated Press reported from Tokyo on July 6 that the Japanese Government had radioed an appeal to all Japanese vessels in the South Seas to join United States naval vessels in the search for Earhart. It add that “Professional and amateur radio operators throughout Japan kept watch for a signal from the missing flier, believing that she might be on one of the Phoenix Islands south of Howland Island.” 
Hayama telephoned William T. Turner of the Division of Far Eastern Affairs on July 6 that the Naval Attaché of the Japanese Embassy had been informed that the Japanese Navy Department had instructed the survey ship Koshu, which was then somewhere in the South Seas, to take part in the search for Earhart’s airplane and to get into touch with Japanese vessels near the place where her airplane is reported to have been lost.
President Roosevelt, at a press conference on July 6, expressed his concern for the safety of Earhart and that he was receiving frequent reports from the Navy Department on the progress of the search for her. He said that the Navy and other government agencies were doing everything possible to find her and he had ordered the search to cover as much territory as possible. 
The Washington Post reported on July 7 that “the Japanese airplane carrier Kamoie and the Japanese survey ship Kooshuu began a search of the Marshall Island area…” The latter was undoubtedly a reference to the Koshu and the former was most probably a reference to the Japanese seaplane tender Kamoi. The Kamoi, while on assignment to the Third Carrier Division, was apparently assigned to search for Earhart; however, the order was cancelled before she could start searching. 
At 2pm on July 10 the Secretary of State, Cordell Hull, sent a telegram to the Ambassador in Japan, Joseph C. Grew, that the authorities of the Navy Department and Earhart’s relatives expressed the opinion that if her plane was forced down on the ocean it may have drifted, because of the prevailing currents, in the general direction of the Gilbert Islands. Hull wrote that in view of the urgency of the time element involved, asked Grew to endeavor to advise the appropriate authorities of the Japanese Government immediately of these facts and state to them that because of the generous offer of assistance tendered by the Japanese Government and because of the continuing interest which the Japanese Government had taken in the search for Earhart’s plane, the American Government suggested that if any suitable vessels or airplanes of the Japanese Government were located in or near the Gilbert Islands they may be asked to be on the lookout for her plane. Hull requested Grew to telegraph such reply as may be made to him by the Japanese Government. The next day Grew telegrammed Hull that the contents of Hull’s telegram had been communicated immediately to Senior Aide to the Navy Minister who stated that no Japanese aircraft were in that area but survey ship Koshu had proceeded toward Marshall Islands and should now be there. Japanese radio stations, Grew added, had been ordered to be on continuous watch for Earhart signals and many Japanese fishing craft in and to east of Marshall Islands had been instructed to be on lookout. The Senior Aide, Grew noted, expressed great willingness to cooperate. 
On the morning of July 12, the Secretary of State had a telegram sent to Ambassador Grew in Tokyo asking him to “convey immediately to whatever authorities you consider appropriate expression of your Government’s appreciation of Japanese Government’s cooperation.” 
The State Department of July 15 issued a press release that contained the text of a message that the Secretary of State had sent to the Japanese Ambassador that day. It stated:
I have the honor to request that you convey to your Government the warmest thanks of the President and myself for the very kind assistance in the search for Miss Earhart which is being carried out at the instance of the Japanese Government.
This cooperation and this evidence of sympathy on the part of the Japanese Government and people are deeply appreciated, and I wish to assure you of the sincere gratitude of the Government and people of this country.
Accept, Excellency, the assurance of my highest consideration. 
Shortly before Hull had written his letter to the Japanese Ambassador, Congressman Allen T. Treadway (R-Ma), sent Hull a letter from an individual from Pittsfield, Massachusetts, in which he suggested that the unfortunate Earhart incident “may offer an opportunity for strengthening the bonds of friendship between the United States and Japan.” Hull wrote Congressman Treadway that it was believed that “the Earhart disaster may serve, in demonstrating the sympathy of the Japanese Government and people towards the American people, to strengthen the bonds of friendship between the two countries.” As pertinent in this connection, Hull wrote, he was enclosing a copy of a press release of the Department dated July 15, which contained a copy of a note of thanks addressed by him to the Japanese Ambassador in Washington. 
At Honolulu on July 18 the Navy announced it was giving up the hunt for Earhart at sunset that day. The naval authorities said the search had encompassed more than 250,000 square miles in every direction from Howland Island and that they believed they had exhausted every possible hope of finding Amelia Earhart and Fred Noonan.
Although the formal American search for Earhart was ending by July 19, on that day the Secretary of State sent a telegram to Ambassador Grew that the “Navy Department this morning suggests that we ask the Japanese Government to suggest to any Japanese vessels plying in Marshall Islands or Gilbert Islands waters that they be continuously on lookout for any traces of Miss Earhart’s plane.” 
On July 20, the American Naval Attaché in Tokyo sent a message to the Navy Department that the Japanese Navy Department desires to release the Koshu from search duties if the American search for Earhart had terminated. Admiral Leahy responded, with a copy to the State Department, notifying the Naval Attaché that the Navy’s search for Earhart had terminated on the afternoon of July 18 and requesting him to convey to the Japanese Navy Department the appreciation of the American Navy Department for their action in making the Koshu available for the search. 
On July 20, the State Department received a message from the Japanese Ambassador (Hiroshi Saito) to Cordell Hull:
Sir: I have the honor to acknowledge, with thanks, the receipt of your note of July 15, 1937 concerning the assistance which is being given by my Government in the search for Miss Earhart.
The Japanese Government and people will, I assure you, appreciate highly the kind sentiments of the President and yourself which you are good enough to convey in your note and which I have had the pleasure of transmitting to Tokyo.
I should like to take the opportunity of expressing the deep concern of the whole Japanese nation that no trace of Miss Earhart has yet been found.
Accept, Sir, the renewed assurances of my highest consideration 
By this time, the Second Sino-Japanese War, which had begun in early July, became the focus of the Japanese and American Governments and whatever good relations had been engendered by the search for Amelia Earhart soon began to end.
