What is your name in Japanese translation?

Answer 1

There is no one word for this, but there are several ways of asking for a person's name. The most direct, and perhaps easiest, way of saying this would be こんにちは、お名前は何ですか (konnichiha, o-namae ha nan desu ka) and is a direct translation to "Hello, what is your name?".

Answer 2

あなたの名前はなんですか？ ~ anata no namae wa nan desu ka?

Improvement:

The sentence above is literal translation, however in direct speech in Japanese pronouns are hardly used, 'Onamae wa (nan desuka)' is common polite way of saying that.
