The seiyuu is Masahisa Sogabe :) He sounds like Konishi, itr's true XD. I didn't find any information of him. I guess he's a new seiyuu like Souma Maeda who is New Zealand (even though, he already make a little work in another anime). I took the info from: http://hetalia.kitawiki.net/index.php?title=Hetalia_of_the_Dead_-_Second_Part
I have no idea who he is but India's listed in the credits as 曽我部雅久 (Sogabe/Sokabe Masahisa- not sure how he reads his name XD) and NZ is 前田聡馬 (Maeda Souma). You can find the latter's profile here (http://www.earlywing.com/actors2.html). Sorry, I've got nothing on India, but I'm assuming both are relatively new >_
