“can I please have your autograph?”

answer:

サインしていただけますか？ (sain shite itada kemasu ka)

In Japanese, autograph is pronounced “Sign”.
The same as when you buy something with a credit card, you need to put your “SIGN” (signature) on the dotted line.

I guess that’s where it originally came from and somehow the word “Sign” became meaning autograph in Japanese. Since it is practically the same thing (asking for someone’s signature).
