My translation skillz aren't up to par, but I think this page explaining why the New Horizon seriesx uses last name + first name.
I think the first paragraph say that Japanese people need to be aware about how foreigners use names.
I think paragraph two talks that if Japanese people switch to first name+last name format that they would lose their identity.
I think the third paragraph say that the Japanese Language Council proposed the idea that last name+first name be adopted from here on out in the New Horizon series.
Is that about right?
