The Nakajima E2N was a Japanese reconnaissance aircraft of the inter-war years. It was a single-engine, two-seat, sesquiplane seaplane with twin main floats.
The E2N was developed in the 1920s for the Imperial Japanese Navy as a short range reconnaissance floatplane suitable for catapult launch from cruisers and battleships. [1] It was a wooden twin-float sesquiplane, carrying a crew of two in open cockpits and having folding wings. This layout gave better downwards view than the monoplanes proposed by Aichi and Yokosuka, and the design was selected becoming Japan's first locally designed shipboard reconnaissance seaplane.
The E2N served with the Navy as the Nakajima Navy Type 15 Reconnaissance Floatplane (一五式水上偵察機). 80 examples were produced between 1927 and 1929 by Nakajima and Kawanishi; of these, two were bought for civil fishery patrol duties. The Navy machines were withdrawn from front-line units in the 1930s, being replaced by the Nakajima E4N, and either being reassigned to training duties or sold to civil buyers.

The Mitsubishi F1M was a Japanese reconnaissance floatplane of World War II. It was the last biplane type of the Imperial Japanese Navy, with 944 built between 1936 and 1944. The Navy designation was "Type Zero Observation Seaplane" (零式水上観測機).
The Nakajima E4N was a Japanese shipboard reconnaissance aircraft of the 1930s. It was a two-seat, single-engine, equal-span biplane seaplane used primarily by the Imperial Japanese Navy.
The Nakajima Ki-4Kyūyon-shiki teisatsuki (九四式偵察機) was the last biplane reconnaissance aircraft of the Japanese Imperial Army. It saw combat service in Manchukuo and in north China during the early stages of the Second Sino-Japanese War.
The Nakajima Ki-6 was a licensed-produced version of the Fokker Super Universal transport built by Nakajima Aircraft Company in the 1930s. Initially used as an airliner, the militarized version was used by the Imperial Japanese Army in a variety of roles, ranging from medical evacuation to transport and training aircraft. It was used extensively in combat zones in Manchukuo and in China during the Second Sino-Japanese War.
The Heinkel HD 26 was a reconnaissance seaplane developed in Germany during the 1920s for production in Japan. It was intended as a smaller, single-seat counterpart to the HD 25, to provide a spotter aircraft for warships, to take off from a short ramp. The HD 26 was a conventional biplane with staggered wings, twin float undercarriage, and an open cockpit.
The Aichi E3A was a reconnaissance seaplane developed in Germany as the Heinkel HD 56 to operate from warships of the Imperial Japanese Navy, which designated it the Type 90-1 Reconnaissance Seaplane. It was a conventional single-bay biplane with staggered wings braced by N-type interplane struts. The pilot and gunner sat in tandem, open cockpits.
The Watanabe E9W was a Japanese submarine-borne reconnaissance seaplane, the first aircraft designed by Watanabe Ironworks.
The Aichi E10A was a Japanese night reconnaissance flying boat of the 1930s. A single-engined biplane, 15 were built for the Imperial Japanese Navy as the Type 96 Night Reconnaissance Seaplane, serving from 1936 but were retired in 1941 before the Attack on Pearl Harbor.
The Yokosuka E1Y was a Japanese floatplane of the 1920s. A single-engined biplane that was designed and developed by the Yokosuka Naval Air Technical Arsenal as a reconnaissance aircraft for the Imperial Japanese Navy, 320 were built as the Type 14 Reconnaissance Seaplane, entering service in 1925 and remained in operational service until 1932.
The Yokosuka Ro-go Ko-gata was a Japanese reconnaissance floatplane developed during the First World War by the Japanese Navy Arsenal at Yokosuka, and one of the first indigenous Japanese aircraft to enter production. There were 218 of these aircraft built for the Imperial Japanese Navy, which remained in use until 1928.
The Kawanishi E11K was a Japanese flying boat of the 1930s. It was designed as a night reconnaissance aircraft for the Imperial Japanese Navy, but was not accepted, the two aircraft built being used as transports as the Type 96 Transport Flying Boat during the Second World War.
The Yokosuka K1Y, also known as the Navy Type 13 Trainer, was a Japanese single-engined biplane trainer of the 1920s. Designed by the Japanese Navy Arsenal at Yokosuka, over 100 were built by several manufacturers, the type being used by the Imperial Japanese Navy well into the 1930s.
The Aichi AB-6, or Aichi Experimental 7-Shi Reconnaissance Seaplane, was a prototype Japanese reconnaissance floatplane. It was a single-engined, three-seat biplane intended for the Imperial Japanese Navy, but only one was built, the rival aircraft from Kawanishi, the E7K being preferred.
The Aichi F1A was a prototype Japanese floatplane of the 1930s. A single-engined biplane, the F1A was intended as a short-range observation aircraft suitable for operation off the Imperial Japanese navy's warships, but only two were built, the Mitsubishi F1M being selected instead.
The Yokosuka E5Y was a single-engine Japanese seaplane used for reconnaissance. The E5Y was also built by Kawanishi as the E5K
The Aichi AB-2 was a prototype Japanese reconnaissance floatplane of the 1930s. It was a single-engined biplane, of which two examples were built, but no production followed.
The Kawanishi E10K, also known as Kawanishi Type T, Kawanishi Navy Type 94 Transport Seaplane and Kawanishi Navy Experimental 9-Shi Night Reconnaissance Seaplane, was a small Japanese flying boat of the 1930s. It was a single-engined biplane intended to meet a requirement for a night reconnaissance aircraft for the Imperial Japanese Navy, but was not selected for production, the single prototype being converted to a transport and operated as the Navy Type 94 Transport.
The Aichi Experimental Type 15-Ko Reconnaissance Seaplane (Mi-go) was a prototype reconnaissance seaplane built by Aichi in the mid-1920s.
The Kawanishi E13K, company designation AM-19, was a Japanese 1930s three-seat reconnaissance floatplane.
