It wasn't a "we can't make/ship big things with relatively low value density" factor (they made cars, after all) and I'm assuming they were making something for domestic consumption (or were they buying Whirlpool fridges for Tokyo apartments?). Was there some tarriff situation keeping them out of this sector?
I have a Panasonic washer and fridge. They're great.

Whirlpool and other western brands have no presence in Japan for appliances. It's all Panasonic, Hitachi, Mitsubishi, Toshiba, plus Haier, and for the cheap brand, Iris Ohyama. Virtually all appliances are made in Japan, or some (usually cheap ones) in China by Japanese companies.
They probably don't bother with the US because American consumers don't want to pay for quality, and they'd have to re-engineer everything for American sizes and preferences. American appliances look nothing like Japanese ones.
Is it even possible to lose this knowledge? Surely they know how to make good reliable products, they simply choose not to...
