The Japanese commentators who do commentary for ladies include Shizuka Arakawa, Ms. Junko Yaginuma, and Mr. Yutaka Higuchi. Occasionally, Ms. Chikako Suguri (Suguri's sister) and Midori Ito also do that.
Shizuka always gives the greatest compliments on pretty much everything about Yuna's skating (techniques, artistry, and mental strength):

A former Olympian Ms Yaginuma is very calm and gentle (and a very beautiful lady). She also always compliments on Yuna's techniques, artistry, and mental strength. She often points out her second jump of the combo bigger than the first one, how wonderful her artistry is, and how mentally prepared she is. She talks less, but observes and analyzes well:

I could not find Mr. Higuchi and do not know what he says about Yuna. But generally, he does very elegant, gentle commentary.
I read that some of the Mao fans were kind of ticked off when Fumie Suguri praised Yuna's skating and was perceived as negative to Mao's skating at Worlds. Yoshie Onda also received similar responses when she was seen as very negative to Mao and praised Yuna at 2008 GPF. But the above three always find positive things about pretty much everyone and it always seems genuine. I like that.
