A Suica card. Over the top appears to be a blue printed ticket - it's a Tokyo 1-day ticket.

My Suica has been vandalised!
It transpires this has a leuco rewritable coating, so special products (like this 1 day season) are literally lasered onto the front (including a map!) and overwritten/removed once used.
Extremely extra but very cool. I've never seen one of these in the wild before.
