Johanna Konta will lead Great Britain's Fed Cup team when they play Japan in the World Group II play-offs on 21-22 April.
Wimbledon semi-finalist and British number one Konta, 26, and Heather Watson, 25, will be the singles players for the tie on hard courts at the Bourbon Beans Dome in Miki, Japan.
Doubles specialist Anna Smith, 29, and debutant Gabi Taylor, 20, also feature.
Britain have not played in the World Group since 1993.
A win would secure their place in World Group II in 2019 but a loss would mean they return to the Europe/Africa Zone next year.
