This is a 1932 or Showa 7 Hōchi Shimbun map of the northern Pacific Ocean tracing the route of Seiji Yoshihara's proposed transpacific flight from Seattle to Tokyo. The map depicts the region from the coast of China to the West Coast of the United States and from the Brooks Range in Alaska to Kyushu and San Diego. Yoshihara, known as the 'Japanese Lindbergh', was sponsored by the Japanese newspaper Hochi Shimbun. Printed by Hōchi Shimbun, the route is illustrated in bright pink and features manuscript notations highlighting the seven proposed waypoints along the trip. Beginning in Seattle, Yoshihara hoped to become the first Japanese national to fly across the Pacific and wanted to arrive faster than Charles Lindbergh and his wife, who had made the trip in twenty-nine days. Even though the official flight was set to begin in Seattle, the route on the map starts in the Bay Are because final modifications to Yoshihara's seaplane were made at a municipal airport in Oakland, California. However, during a 'training' flight, Yoshihara crashed his plane just outside that airport in Oakland and broke an arm and a leg in the accident, ending this attempt before it even began. The possibility exists that the manuscript notations present on this map are done in Yoshihara's own hand. Since this map is a reverse cyanotype, only a few examples would have been created due to the difficulty in the printing process. This likely means that the map was created specifically for Yoshihara's attempt, a presumption that is only reinforced by the fact that Hōchi Shimbun is the publisher.
A Short Biography of Seiji YoshiharaSeiji Yoshihara was born in 1904 and by 1932 had made several unsuccessful attempts to fly across the Pacific, including an aborted attempt in 1931 when he was forced to crash land his aircraft into the Pacific Ocean near the Kurile Islands. Not all of his adventures ended in failure, however. He had successfully completed flights from Berlin to Tokyo. Little is known about Yoshihara following his unsuccessful attempt to fly across the Pacific in 1932.
Publication History and CensusThis map was published by Hōchi Shimbun in on March 1, 1932 or Showa 7, a few months before Yoshihara planned to begin his flight across the Pacific. We are unaware of any other examples of this map either in institutional collections or in private hands.
Very good. Even overall toning. Light wear along original fold lines. Blank on verso.
