Great Britain's Davis Cup qualifying tie against Japan is a "great opportunity" for others in the absence of Jack Draper and Cameron Norrie, says captain Leon Smith.
World number 77 Jacob Fearnley is the highest-ranked Briton in the squad in his first call-up to the team.
Scotland's Fearnley, who had a meteoric rise in 2024, is joined by Billy Harris and doubles specialists Joe Salisbury and Neil Skupski.
British number one Draper has opted to miss the tie to continue his rehabilitation from a hip injury, while Norrie withdrew with illness.
