Yes.

In other words, both are correct. Choosing the one that's appropriate in a specific context...is a tricky problem.

Germany is more correct because they write " made in Germany" on German products.

But that was mandated by the British because the zeitgeist was that German products were shoddy crap.

So since the Japanese write 日本製 on their products you agree all maps should write it 日本 then?

I bought a zojirushi rice cooker last year, It said 'made in Japan'. Not quite sure what those characters are in your comment or what you are trying to say.
