. Deliveries commenced on 30 March 1965, and commercial operations began the following month. The majority of orders for the type were issued from various Japanese airliners. While sales to such customers were swift in the YS-11's initial years of availability, this limited market soon became saturated, leading to a slump in demand.
Following efforts to acquire more sales from international customers, including the development of the improved ''YS-11A'' variant, production of the type ceased during 1974. Ultimately, while the YS-11 had demonstrated Japan's ability to produce an airliner, NAMC had accumulated considerable debts and the type is largely considered to be a commercial failure. Large numbers of the type continued to be in service until 2006, at which point tighter Japanese aircraft regulations imposed by the
necessitated either the withdrawal or refitting of all YS-11s. By 2018, only a single example reportedly remained in commercial service.

(MITI) identified a requirement for a short-haul airliner to replace Douglas DC-3s flying on Japan's domestic routes, and encouraged companies in Japan's aircraft industry to collaborate to develop and produce a domestic airliner to meet this need. Towards this purpose, in May 1957, the ''Commercial Transport Design Research Association'' was established and the availability of government

guaranteed. From the government's viewpoint, the development of such an airliner was viewed as a key initiative towards the post-war revival of the nation's aircraft companies, which came in addition to the serious ambition to become a major international competitor in the global airliner business. Furthermore, while this requirement had been conceived primarily in a commercial context, there was an early recognition of the value for multiple branches of the Japanese Defense Agency (JDA) to be readily able to adopt the type as well; as a philosophy, this not only extended to the prospective airliner itself, but the various technologies involved in its development and manufacture.
In response to this encouragement, during 1957, a

Two years later, this partnership was formalised as the ''Nihon Aeroplane Manufacturing Company'' (NAMC).Endres 1996, p. 22.Taylor 1966, p. 107. The ownership of NAMC was initially divided between the Japanese government, which held 54% of the shares, while the constituent aircraft manufacturers held an 18% stake and several components/materials suppliers owned 11%; the remaining shares were small stakes belonging to various banks, insurance companies, and stock firms who chose to invest in the programme. However, NAMC was essentially a "paper company", being reliant upon both personnel and infrastructure provided by its constituent manufacturers.Odagiri, Odagiri and Akira 1996, pp. 224-225.

, were copied from foreign sources; such information was gleaned from a combination of Japanese airlines, trading companies and diplomats. Throughout the YS-11's production lifetime, its electronic equipment, avionics, mechanical and fuselage components were supplied by a combination of Japanese companies and foreign suppliers.
Name
The “YS” of the YS-11 comes from a combination of the first letter sounds of the two Japanese words yusō (transport) and sekkei (design), which refer to the Association for Research on Transport Aircraft Design (Yusōki sekkei kenkyū kyōkai). Meanwhile, the first “1” of the “11” refers to the various engine candidates considered for the YS-11; the Rolls-Royce Dart RDa.10/1, which was the engine selected, had been designated “number 1.” The second “1” refers to the aircraft specification plan selected for the YS-11, which had been one among many plans that differed by wing placement and size. There had also been a “plan 0” at one point.
A catchphrase developed around the public reveal of the YS-11 mockup, which was “Let’s meet on the 11th at Sugita in Yokohama.” Here, Yokohama represented the “Y,” the Sugita neighborhood stood for the “S,” and the 11th referred both to the plane and to the date of the public reveal (December 11, 1958). Because of this, it became common to read the “11” in “YS-11” as “eleven” (jūichi in Japanese). For those involved in designing the plane, meanwhile, the designation had originally been pronounced “YS-one-one” (or YS ichi ichi).

from Nagoya Airport; it was soon followed by the second prototype, flying on 28 December 1962. Early flight testing revealed several issues to troubleshoot, including poor steering, excessive vibration and noise.Odagiri, Odagiri and Akira 1996, p. 225. There was also an acute lack of safety during sideways maneuvers; the wake of the propeller produced abnormal forces that inclined the aircraft to the right; all of the rudders were ineffective; and the maneuverability was worst of all. These problems produced a tailspin during the flight test, and were the direct cause of a crash. This was known as the “three rudder problem.”

(FAA) certification followed on 9 September 1965. Prior to applying for certification, the FAA had been involved in the programme at NAMC's invitation, performing informal project reviews so that defects could be identified and eliminated early on.
During the late 1960s, a lack of significant international sales led to the programme incurring persistent losses, the outstanding debt eventually growing to $600 million.Anselmo, Joe "Milestone for the MRJ." '' Aviation Week & Space Technology'', 24 October 2014. Accessed: 25 October 2014. Due to the organisation of the programme, the aircraft manufacturers themselves did not have any of this debt apportioned to themselves, NAMC being held solely responsible; Mercado criticised this approach as it meant there was no incentive for the individual companies to make cost savings while simultaneously guarantee profit to them on every plane produced. Furthermore, it had been alleged that some participants saw the YS-11 as only a training programme to develop their employees' skills, rather than a serious commercial initiative; some participants chose to rotate large numbers of staff in and out of the project for brief periods before re-tasking them to work on internal projects.
Marcado claims that the programme's operational mindset was closer to that of a military project than a commercial one, while a preoccupation with government-issued performance criteria obstructed considerations towards the actual desires of the commercial operators, such as operating costs and cabin configuration, that the YS-11 was marketed towards. As this was Japan's first, and for a long time only, post-war airliner, NAMC lacked any staff with experience in marketing towards airlines, a disadvantage against the salesmen of rival airframers. This failure to address a crucial factor in acquiring new customers has been attributed as a major contributing cause of the programme's poor commercial reception.Odagiri, Odagiri and Akira 1996, pp. 225-226.
The end of the YS-11 programme was precipitated by the 1971

, which led to an appreciation in the value of the Japanese yen and the resulting impact upon the nation's economy. By this point, it was clear that there was little chance that the YS-11 could ever come close to breaking even. These myriad factors contributed to the decision for production to be terminated after the completion of 182 aircraft. On 11 May 1973, the last YS-11 was delivered to the

Early deliveries were mainly made to Japanese airlines, but orders for the type slowed drastically after the satisfaction of the outstanding needs of the Japanese commuter airlines for which the aircraft had been designed.

agreement was signed between NAMC and Hawaiian Air Lines, a move which was hailed as the "first step" in the programme's new America-focused campaign. While a number of aircraft would be sold internationally, these were often at a loss as the sales price had been set so low, deliberately as to undercut competing airliners, but paid little heed to production costs; this deficit led to losses mounting more rapidly than anticipated.

, who had been seeking the optimal modern airliner to serve their existing routes, which mostly comprised a number of small, mountainous airports. After evaluating numerous aircraft around the world, the company determined that the Japanese airliner was the most suitable; according to Piedmont's president, Thomas H Davis: "The YS‐11 was the only one we could find which would do it on an economical basis"."The YS‐11 Solves a Problem for Piedmont." ''New York Times'', 31 May 1970. During October 1967, Piedmont Airlines ordered a batch of ten YS-11A-200s along with an option for an additional ten aircraft for $22.5 million.Endres 1996, p. 24. The company was so impressed by its performance, it both exercised the option for ten aircraft and purchased an additional YS-11, operating a combined fleet of 21 YS-11s by mid-1970. Piedmont would be the type's largest international operator; ultimately, no other airline would place another order of this scale.

Commercial sales of the YS-11 began to stall without a stable structure in place for sales. Especially outside of Japan, the YS-11 was forced to compete with other country's models with long-term low deferred interest payments. Nor was it rare for

to have to sell the YS-11 at a discount, as this was Japan's first commercial airliner since the end of World War II, and had no proven track record. Additionally, it was also said that there was mismanagement of the program's cost management, as initial estimates had neglected to include the cost advertising or company administration. Moreover, because multiple companies were involved with the aircraft manufacturing, it was unclear who held ultimate responsibility, nor could the price of delivered parts be reduced. An increase in former government employees appointed to the company began to spread a culture of bureaucracy, making necessary drastic management reforms impossible and further increasing the program's deficit.
In particular, there was deficit in sales activities outside of Japan that were a result of fundamental problems in NAMC's administrative activities in the United States, as indicated by the Japanese government

NAMC had no experience of selling passenger planes, and so it concluded a contract with Charlotte Aircraft without conducting an investigation into the company's trustworthiness or business practices, nor without creating a clause in the event Charlotte Aircraft refused to conduct sales.

By 1994, 112 YS-11s remained in service; the lengthy service life of the type, despite the short manufacturing lifespan, has been hailed by some officials as evidence of the type being successful in some respect. The YS-11 was slowly phased out by Japanese airlines up until the early 2000s, at which point the withdrawal rate spiked in response to new directives issued by the
that required all commercial aircraft in Japan to be fitted with a Traffic Collision Avoidance System (TCAS); any aircraft lacking TCAS were forced to cease operations at the end of 2006. Reportedly, equipping a YS-11 with TCAS had been estimated as costing around ¥100 million (about

Additionally, the Shinkansen and the YS-11 were both developed by individuals who were involved with the creation of military aircraft (this was to be expected with an airplane like the YS-11, but men like Migi Tadanao and Matsudaira Tadashi were also involved with the Shinkansen).
