How do you write the name Amaya in hiragana?

Answer 1

amaya in hiragana is あまや　but normally names are written in katakana so the katakana version is　アマヤ.

Improvement:

Amaya is an originally Japanese name and has no specific reason to be written in katakana unless the one writing it wants to do so to simplify or etc. It has many ways of writing including simple hiragana あまや or kanji complex like 天矢 etc.
