Not just for SUITA only.

Here it is the example of iromono with su: https://www.flickr.com/photos/109151...7637827771915/

So presence of "Su" is not a distinctive trait of SUITA toishi.

And the absence of "Su" does not mean that the stone is definetely not SUITA because there are so called Sunashi Suita ( 巣無し巣板 ) stones that are SUITA, but have no Su at all.

I also have an Iromono and noticed one day under magnification that it had Su. It's a fantastic stone. Dead easy to get excellent edges off of it, but not quite as keen as what I get with Nakayami Asagi I own. Here's a pic of it along with some Nagura and an old arkie.
