Imperial Japanese Airways
Open-knowledge reference entry
Japan Airways Co.Ltd (大日本航空株式会社, Dai Nippon Kōkū Kabushiki Kaisha; also known as Imperial Japanese Airlines, Great Japan Airlines or Greater Japan Airlines) was the national airline of the Empire of Japan during World War II.
History
With the start of the Second Sino-Japanese War, there was a tremendous need for air transport capability by the Japanese military, which had traditionally drawn on the resources of the civilian national flag carrier, Japan Air Transport, for its charter requirements. As Japan Air Transport's capacity was limited, conflict arose between the Imperial Japanese Army and Imperial Japanese Navy over priority, and the government saw the need for the creation of a single, national monopoly. The government bought a 50 percent share of Japan Air Transport, and renamed it the Dai Nippon Kōkū in December 1938.
In the late 1930s, Dai Nippon Kōkū operated an extensive international network with a combination of foreign and domestic aircraft. The airline was linked with Manchukuo National Airways for routes in Chosen and Manchukuo, and also had routes in the Japanese occupied portions of mainland China. Internally, Dai Nippon Kōkū linked the Japanese home islands with the Kwantung Leased Territory, Korea, Taiwan, Karafuto, and Saipan and Palau in the South Seas Mandate. The airline served the west and central Pacific areas using converted military flying boats. The airline operated some longer charter flights, including flights to Iran and Italy in 1939, and had long-term plans to serve Europe through two routes, one passing through Manchuria and Central Asia and the other running from Bangkok through India and the Middle East.
After the start of the Pacific War in 1942, the airline became completely government-owned and operated as two separate units under the control of the Imperial Japanese Army and Imperial Japanese Navy respectively. By 1943, the airline flew a circular military convoy route from Taiwan through the Philippines, Indonesia, Singapore, Thailand and southern China.

Why this record matters
“Imperial Japanese Airways” is worth following because a concise public description often conceals a longer documentary argument. Here, Imperial, Japanese and Airways provides the most credible route into that argument.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jun 26, 2026. The linked authority identifier is Q5158887. VIAF identifies the subject as 259900306. 1 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1938, 1939, 1942 and 1943.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
