Ex-Terunofuji was doing commentary duties for NHK while showing the new Asahifuji's mae-zumo bout. When asked about the granting of the ambitious shikona, he said that it was Miyagino's (ex Isegahama's) wish. He questioned the timing of granting of the name (suggesting that it might be more appropriate after he's actually accomplished something), but Miyagino was insistent, so Asahifuji he became.
Also said that people should temper their expectations, and that he still has along way to go before he becomes the rikishi everyone expects him to be.
