Talking [Q] Help Samsung Galaxy S4 NTT DoCoMo SC-04E

I badly want to root my Samsung Galaxy S4 NTT DoCoMo SC-04E but I don't know how. I have seen steps on how to root the Samsung Galaxy S4 but will it do for my model? And if ever I have rooted it, will all roms work for me? I just want to remove the bloatwares and unnecessary applications. Thanks
