Thye still could have attacked the Chinese just a few years later, when they became a world economic power. Sony was founded in 1946. Alongside consumer devices such as TV and video, cameras, and game consoles, the company has introduced various professional audio equipment such as microphones, DATs, MTRs, and effectors.
Toshiba was founded in 1939 by the merger of
Shibaura Seisakusho (Shibaura Engineering Works)
[15] and
Tokyo Denki (Tokyo Electric).
Toyota started in 1933. Nissan started in 1911. Datsun started in 1931.
With what? They were an impoverished nation by then, the war destroyed their economy. For a decade their only export of note was cameras. Until the 1950's when they started to export simple transistor radios.
And come on, really? At that time Toshiba was almost exclusively involved in power generation and lighting.
Toyota? Are you even aware that their product prior to the war was looms? It was the largest producer of mechanical looms for their textile industry. They started to make trucks primarily for their own use in the 1930s, but also for other companies as they were already having problems importing US made trucks. They left the textile industry during the war as their factories were bombed to rubble, and only survived as they were able to get a contract repairing US occupation force vehicles. They did not get back into the vehicle business until the 1950s.
After the war, Nissan was not actually making cars. They were importing pre-war Austin 7 cars from the UK in the crate and just assembling them. And braniac, Nissan is Datsun. They are the same freaking company! Nissan absorbed Datsun in 1933, two years after it was founded. The name Nissan was used for their commercial vehicles, and Datsun for their passenger vehicles. In the 1970's they started to retire the Datsun name, which is what it was known as to most of the world as commercial vehicles were not a big export business for them. I remember 1984 clearly, as that was the final transition year with the cars badge changing from "Datsun" to "Datsun by Nissan" for a single year before Datsun vanished forever.
Sony was entirely post-war, and made consumer audio electronics. They also almost went bankrupt many times until the mid-1970s.
I am surprised you did not bring up Nintendo. Founded in 1889 as a playing card company. Which by the late 1960's expanded to chess boards, go, and other board games. Then in the early 1970s getting involved in the arcade business.
Or Yamaha. Founded in 1887 to make musical instruments. But like Toyota they lost their factories during the war so entered a sideline making copies of a pre-war 2 stroke German motorcycle. But they are still primarily a music company, which is seen as their logo is three tuning forks.
Or Honda, which until January 1945 made piston rings. Yep, that's it, piston rings. Literally a "garage business", but they lost their factory not because of the war but from the Miwaka Earthquake. When the war ended they salvaged what they could, and started to make 50cc engines that could be bolted onto bicycles. That was their only product until 1949 when they finally were able to design their first motorcycle, a 100cc 2 stroke.
Or another loom company, Suzuki. It was number 2 in the loom industry in Japan, behind Toyota. But in 1951 the company almost collapsed when the cotton industry took a nose-dive, so copied Honda and started to make bolt on engines for bicycles. A business Honda had already vacated when they moved to making their own motorcycles.
And they were under US Occupation for almost 7 years. You really do fail big time at history, that is obvious. I guess somehow they were unseen by US Occupation forces swim to China, carrying with them a huge number of 150 and 250 cc motorcycles and take over China.
