This is a vintage Japanese wooden mask called Okina from late 1900's to early 2000's.
Among all Noh masks, the Okina (old man) mask is considered particularly sacred and has been at times treated as the embodiment of god, bringing longevity and prosperity to families. The mask is the oldest of the Noh repertoire and represents an older male with long white beard expressing wisdom.
This mask will be a great wall decoration.
