The Emi 24 was the second aircraft specially built by Itoh for the Imperial Japan Flying Association Long Range Competition in Shanghai. The aircraft was commissioned by aviator Yozo Sato and sponsored by Akito Prefecture, after which the aircraft was named Akita-Go.
It was a single-seat single-pillar biplane with a monocoque fuselage, powered by a German Maybach six-cylinder liquid-cooled engine with 320 hp.

After the cancellation of the competition, the aircraft was completed in October 1921 as a light transport. During the tests, it became clear that the design of the aircraft was not perfect and the project was closed.
