Pro Leather

What kind of leather is Deguchi leather?

This leather is in the Mizuno Pro-Limited gloves, but I don't know if it's full-grain, steerhide, or top-grain. Can someone educate me on this?
But I read that there are three types of glove leathers: full-grain, steerhide, and top-grain. Where does Deguchi fit in?
Or am I completely off the mark here?

It's Deguchi duh

its Japanese, its supposed to be softer than all the other leathers.
