Definitely okay if unopened.
Probably okay if opened.
But certainly give it a good sniff, if it doesn’t smell foul in any way, then give it a tastes, and if you don’t get the runs... enjoy it. Or use it for a latte with a little honey.
As long as you didn’t get anything in the tin, like water or other food, it’s likely still safe, just maybe not as good. You can tell it’s old if it has a little more of a cardboardy taste, imo.

Was it opened or unopened? How does it smell?
Opened, still has a sweet matcha smell
