What is written on the gate of the hidden leaf village?

Answer 1

On the left gate, in hirigana, A(ah). On the right gate, in hirigana, I(ee).

Answer 2

The hiragana あん (an) is painted on the four entrance gates of the village (one hiragana on each door).[21] This means "hermitage" or "retreat". In kanji, the character is "庵". There are also torii built all around the perimeter wall of the village.[22]
