Japan stormed back into the World Group of the Davis Cup after a 26-year absence on Sunday with a 4-1 victory over India.
Ace Kei Nishikori posted a comprehensive 7-5, 6-3, 6-3 win over Vishnu Vardhan at a windswept Ariake Colosseum to give the hosts an unassailable 3-1 lead in the opening reverse singles match.
Nishikori, ranked 64th in the world, broke Vardhan in the 11th game of the first set, powering a forehand winner past the Indian. Nishikori then closed out the set with an ace.
