The WRU have confirmed that Wales will take on Japan as part of the 2016 November Tests.
The news was revealed as the WRU announced a nine-year extension with current kit supplier Under Armour, who will now also sponsor Wales' November internationals.
The clash with Japan is the latest to be added to the 2016 'Under Armour Series' match schedule and they face Wales on Saturday, November 19.
The Wallabies kick-start the Series on Saturday, November 5, and the Pumas visit Cardiff on Saturday, November 12, with the Springboks completing a quartet of top quality opposition for Wales on Saturday, November 26.
"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 Millennium Stadium in November," said Wales head coach Warren Gatland.
"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."
