google translate my friend, google translate
I am afraid this does not really translate into Japanese because they do not use those words in greetings. Its a very Hindi sounding greeting not Japanese Well, Hindu is not a language it a religion, I think you meant Hindi which in that case you can use Assalamu Alaikum if they are Muslim. But to roughly translate it plainly in Hindi would be like... Dost mein tomko shantise abhibadan karta hoon.
