Wales will face Japan in one of four Tests inked in for their autumn series.

Japan, who won three of their four games in the Rugby World Cup, will be the third of four November Tests in a programme which kicks off against Australia on November 5 at the Principality Stadium. Wales will then host Argentina on November 12 and then welcome Japan a week later.

The four-Test programme concludes against South Africa on November 26.

The news comes on the day the Welsh Rugby Union announced a new nine-year deal with kit manufacturers Under Armour which extends the agreement until 2025.

Wales coach Warren Gatland said: "The Under Armour Series will be about testing ourselves against the best sides in the world, and with Japan now completing the fixture line-up for 2016, we have four teams from World Rugby's top ten coming to the Principality Stadium in November.

"Under Armour's support for Wales has been unerring in every aspect since they came on board in 2008 and it is great news for Welsh rugby that they will be working with us until 2025."
