Both Yamaha and Kawasaki are notable for being the only Japanese motorcycle manufacturers that did not produce cars.
That is not to say both did not explore the idea with Kawasaki developing the Kawasaki KZ360 Kei Car prototype (aborted because dealer network could not be establish - yet could have worked had Kawasaki and Hino Motors not been split from Isuzu), while Yamaha would notably produce the Nissan A550X prototype before going on to work with Toyota on the Toyota 2000GT IOTL.
Intriguingly Yamaha themselves started work on a Kei Car in 1958 before they decided to bow out and instead develop a sportscar rather unusually at the low volume end of the range after the Kei Car segment was soon swamped by rivals.
With that niche in mind, ONO Shun and YASUKAWA Tsutomu set up the Yamaha Technology Institute and in September 1959 went on a grand tour of American and European car manufacturers to seek knowledge and inspiration. They noticed that sports and GT constructors mostly still worked on a one-by-one basis, by hand, rather than the mass production way. At that time, Japan still lacked the huge resources and facilities to mass produce, and YASUKAWA and ONO san thought about the higher power, lower production area of car production for the discerning enthusiast.
On their return to Japan in November, they set up the Yasukawa Institute, aiming at high performance sports cars. Soon the Institute had purchased a MGA twin cam from a US Occupation Forces army officer (as officially unable to buy foreign made vehicles) and a Facel-Vega Facelia, another DOHC powered car. These were tested and dismantled to gain knowledge and understanding. Ironically both of these engines were withdrawn from the market by their manufacturers due to serious reliability problems. Maybe from that, Yamaha created a robust and efficient 1.6Litre DOHC of their own for the Yamaha YX30 prototype.
But a serious slump in scooter and motorcycle sales in Japan made Yamaha cut its costs, and the engine would be shelved and both Yamaha Institutes were broken up. This slump caused Yamaha financial difficulties and this is probably the cause for Nissan and Yamaha being entered into an imposed partnership, by a mutual financing bank in 1962 that led to the Nissan A550X project.
What if however Yamaha not only managed to avoid the slump in scooter and motorcycle sales in Japan, but also decided to return to developing a Kei Car with either a regular car or continuing with carving out its own niche by producing its own production Kei Car analogue of the 1962 Honda S360 sports car prototype for the Japanese domestic market?
Whilst of course still building engines and doing contract work for other car manufacturers' vehicles as in IOTL Yamaha as well as reminiscent of IOTL Lotus Cars with its Lotus Engineering offshoot?
