Hope it’s okay to make a thread for this. Someone is trying to identify the character on this necklace. It might not even be one used in Japanese, but… I’m curious. Mind you, it’s possible it could be flipped the other way.
I asked a Chinese speaking friend (native) and she had this to say:
“It is an old style writing of 寿. It pronounces like ‘show’ and exclusively used with birthday and age, usually for old people or to describe the longevity of a thing, animals for example. When old people celebrate their birthday, you see it on the wall and on the cake sometimes.”
