If they are made in Japan they are probably ART, same as originals. You could unwrap one and check?

 They have 1 piece oil rings...I'd replace them with 3 piece units.

I believe they where ART.  I also changed to a 3 piece oil ring.  I went with Honda for any gaskets and O-rings I needed.  A little over 2500 miles and running like a charm.
