Early route-proving. Three Kawanishi K-7A four-passenger cabin floatplanes at anchor at Mogpo, Korea in October 1925 during a trial flight from Osaka to Mogpo and Shanghai. The aircraft are, from left to right, J-COBC, J-CODE and J-COCD.

Over one hundred examples of the Nakajima 5 two-seat open-cockpit biplane were built, mostly for the Japanese Army. Some were later civilianised and together with a small number of original civil machines they served successfully with flying schools in the twenties.

Kawanishi K-10 J-CODF (260-305 hp Maybach Mb IVa 6-cyl water-cooled in-line) was used by NKKK, initially as a mailplane on the Osaka - Seoul - Dairen route. The K-10 could carry four passengers in a cabin immediately behind the engine bulkhead. We now know that this example, the second of the two built, had a relatively short career of less that six months before being destroyed.

The second of the two Itoh Emi 13 trainers built, J-HUDE was powered by a 90 hp Curtiss OX-5 eight-cylinder water cooled vee. Prominent features visible in this photo include the external radiator and the 'elephant-ear' ailerons. The aircraft was used for training at the Itoh company's beach airfield at Tsudanuma but was cancelled as destroyed in October 1921.

The sole example of the Shirato 31 trainer, powered by a 120 hp Le Rhone nine-cylinder air-cooled rotary engine. The aircraft wears Shirato's trademark target on the fuselage but no registration is visible. Formerly J-TANO it was re-registered J-HUKL in 1923 and was unfortunate not to attract any orders as the basically simple design was ideal for instructional use.

Another one-off machine was the Fukunaga Tenryu 3 biplane J-HUAB which was actually the Itoh Emi 2 considerably modified by Asao Fukunaga over a period of time. Originally designed in 1917, it was powered by a 35-45 hp Gregoire Gyp 4-cyl water-cooled in-line engine of 1910 vintage which had been used in several earlier aircraft and, even by 1917, was 'old technology'!

The Ogawa 5 trainer was a modified light-weight version of the Nakajima 5. The top wing was moved back, thus producing a negative stagger, to counter the reduced weight of the 70 hp Renault engine which replaced the 150 hp Hall-Scott of the original design. Large ducts were added to supply cooling air to the Renault. Only one example, registered J-HUFG, was built and the venture was unsuccessful.
