But yeah, there's nothing official about having your name on your Suica, unless; see below.
If you lose your card, and you don't have your name on it, I guess that's just it.

I think the only REAL registration you can do for a Suica is if you have it set up as a commuter pass for your work or school, in which you can fill out paperwork and they print your designated route on the Suica card, and they may be able to pull up your name if you lose it. But if you're just a tourist or something without the commuter pass Suica, I don't think there's any way to track it.

Gotcha, thanks!
