Token Identification Y.L

Can't remember where I got this token from but it was already in the holder and labelled Y.L . The reverse/obverse are identical. I haven't been able to find anything on it especially due to the lack of writing on the token. Upside down it could possibly be a T.h instead of Y.L . Any info on this would be great! The diameter is about 25 mm and weight is approximately 5 grams.

Looks Japanese
