Vancouver, BC (SportsNetwork.com) - Sixth-ranked Milos Raonic will compete in Friday's opening singles rubber, as Canada is ready to host Kei Nishikori-led Japan in a best-of-five opening-round Davis Cup showdown.

Raonic will take on 85th-ranked Tatsuma Ito on Day 1, while the second opening singles match will pit the world No. 4 Nishikori against No. 62 Vasek Pospisil.

Saturday's doubles has a Canadian pairing of Pospisil and 42-year-old Daniel Nestor facing a Japanese duo of Go Soeda and Yasutaka Uchiyama.

Sunday's reverse singles call for Raonic to battle the U.S. Open runner-up Nishikori in a marquee matchup and Pospisil to tangle with Ito on the indoor hardcourt at Vancouver's Doug Mitchell Thunderbird Sports Centre.

Nishikori is 12-2 in his career Davis Cup singles, while his fellow top-10 star Raonic is 13-4.

Canada and Japan will square off in a repeat of last year's first-round clash. The 2014 encounter in Tokyo saw both sides depleted by injuries and it was the Japanese who extended their perfect record against the Canadians to 6-0.

The Canadians are captained by Martin Laurendeau, while the Japanese are guided by Minoru Ueda.

The winner in Vancouver will move on to face Belgium or Switzerland in a quarterfinal in July.
