My name in Japanese

Koniichiwa! I just want to know if someone could teach me how to write my name in Hiragana and Katakana..

こんにちは！ Your name looks most likely like しゃまいん (shamaeen) or しゃまん (shamann) depending on whether or not you pronounce the 'ee' sound. Same as with katakana, your name is most likely either シャマイン or シャマン depending on pronunciation. Hope that helped!
