The Japanese Language is so fundamentally different that it is neigh impossible at present to make a proper translator. If we look at paid products it is probabliy possible to find better ones but the ones I use generally return things like this. Not just for things I write but for when i have to translate long email which are probably not especially relevant to me. I pop em in one of these translators and then pick through what comes out. Sometimes to great comedic effect.

It is, however, a decent indicator for when I write stuff. If I write something, put it in one of these translators and get a grammatically decent, spell-perfect sentence back. . . .
I pretty much fucked up the Japanese. Very few proper Japanese sentences come out translated as proper English sentences. If I don’t have at least 1 . . . . [base verb] . . . construction every 3 sentences I recheck my Japanese.

For instance: “True goods have various thickness of meat.” Is a bit translated for my report on Gas Insulated Swtichgear. Not even kidding. And I’m not changing it either because in Japanese . . . it is relevant.
