Poznámka:
Note:
Viz historie. In October 1927, the Teikoku Kaibo Gikai (Imperial Maritime Defence Volunteer Association) decided to order two aircraft, and in turn to lend them to the Asahi Shimbun which was sponsoring a regular air route between Tokyo and Osaka, as part of the Tozai Teiki Kokukai (East-West Regular Air Transport Association) that would eventually begin in December 1928. Orders for the two aircraft were placed with Kawasaki, and would be a version of the Army Type 88 Reconnaissance Aircraft, having passenger accommodation and the ability to operate on floats This redesign was made by Dr Richard Vogt and Hisashi Tojo. The two aircraft were completed in October 1928 and identified as Giyu No.4 (J-BAKH) and Giyu No.5 (J-BALH) respectively. Major structural changes included a shortened upper wing, an increase in span and chord on the lower wing and N interplane struts. The four-seat passenger cabin, aft of the cockpit, could be converted for aerial photography and mail carrying. When equipped with floats, an enlarged rudder was used and it extended below the fuselage. Their use on the Tokyo-Osaka run was short-lived, with the activation of Nihon Koku Yuso K K on the same route.
Many cities were visited, and lectures were given by those flying on the KDC-2s to further promote the potential of aviation. When the tours ended, the aeroplanes were used by Asahi Shimbun for courier work, aerial photography and transport duties. They were also used for regular mail flights between Tokyo and Niigata, and for courier flights to Manchuria during the Manchurian Incident.

History:

In October 1927 Teikoku Kaibo Gikai (Imperial voluntary association of maritime defence) decided to order it from Kawasaki Kokuki K. To. two of the aircraft, which was to be leased to the group the Asahi Shimbun, which was the main and most important sponsor of a regular air connection between Tokyo and Osaka. The development of the aircraft began in December 1927 and as a basis for the development was taken army reconnaissance aircraft type 88. These aircraft were in the hull of a place for a cabin for four passengers and it is possible to adjust for float landing gear.
The redevelopment of a fighter airplane by a team of technicians led by German engineer Dr. Richard Vogtem and japanese designer Hisashim Tojoem. Both planes were completed in October 1928 and marked Giyu no. 4 (J-BAKH) and Giyu no. 5 (J-BALH). Adjustments to the aircraft involving structural changes, including reduction of the margin of the upper wings, increasing the depth of the bottom wing and change mezikřídelních struts. Four-passenger cabin was at the back of the airplane and could be used for aerial photography or postal transport. After the installation of the floats, was the increase of the area of the rudder and added the vertical area under the fuselage.
The deployment of the aircraft on the route Tokyo - Osaka was short, the Asahi Shimbun has suspended its operations and cancelled scheduled flights throughout Japan. At the beginning of July 1929 was made several promotional flights around eastern and western Japan. When a promotional campaign to promote civil air transport has ended, both aircraft used the Asahi Shimbun for courier flights, aerial photography and for performance of transport tasks e.g. mail flights between Tokyo and Niigatou, and for a courier flights to Manchuria during the Mandžuckého the incident. In September 1930 he was Giyu no. 4 heavily damaged in a takeoff on the river Kizu in Osaka and has been all year repaired. After returning to the service was in June 1932 when a courier flight to Manchuria forced to make an emergency landing, was at the landing again badly damaged and was subsequently scrapped after the nalétání 229 hours of flight time. After the Manchurian incident plane Giyu no. 5 resumed regular flights between Tokyo and Toyamou or Tokyo and Sendaií, from this service was eliminated in 1935 and flew a total of 723 hours.
