Gold priced in yen rallied to session highs on Thursday after yen came under broad pressure following a downgrade to Japan' sovereign ratings.

Ratings agency Standard & Poor's cut its rating on Japan's sovereign debt to AA- from AA and kept its outlook stable and said the downgrade reflected the view that the government's debt ratio would continue to rise.

Yen/gold rose to a session high of 111,475 yen an ounce before trading at 111,297 yen at 0802 GMT, showing a 0.5 percent gain on the day.

Dollar-priced spot gold extended losses, touching an intraday low of $1,339.78 an ounce, down nearly 0.5 percent on the day, under pressure from the rise in the U.S. currency against the yen. JPY=
