How many Toyota and Honda factories have announced they are closing their doors? Are they in trouble? If not, then they don't need a bailout. Honestly, I don't know how they are doing, but I haven't heard of any major shut downs concerning those companies.
I'm sure if Toyota and Honda wanted to move their main base of operations from Japan to the USA and reincorporate in the USA, they would be eligible for a bailout (if they needed it).
However at this point, since they are Japanese corporations (and incorporated in Japan, paying their tax rate), they need to get a bailout from the Japanese govt.
