Itoh Emi 1

By early 1915 Otijiro Itoh had established the Itoh Aeroplane Research Studio and an associated flying school and by that autumn had completed his first design, the Emi 1. The "Emi" was a respectful nod to the district of Osaka where he grew up.
The sole Emi 1 was a three-bay biplane with a fabric covered wooden structure. Its wings were of equal span and joined by parallel pairs of interplane struts. The upper wing was well above the fuselage and the lower ones mounted on the lower fuselage longerons. The Hyabusa-go's French, 35–45 hp (26–34 kW) Grégoire Gyp four cylinder, water-cooled inline engine powered it. Its pilot had an open cockpit. At a time when there were few prepared airstrips, landing gear needed to be robust and the Emi 1's gear had two wheels on each leg.
Its first flight was on 11 November 1915.
On 8 January 1916, not long after the first flight, Itoh flew the Emi 1 from his base at Inage Bay to Tokyo. This took 55 minutes and was the first flight to Tokyo. He later flew it to 58 Japanese cities, partly to advertise his aircraft and partly to raise air-mindedness in Japan. The Emi 1 was the second successful Japanese aircraft, following the Narahara 4 ''Ohtori-go''.
Later the Emi 1 was re-engined at Inage Bay with a 50 hp (37 kW) Hino Type, remaining in use with the flying school.
