Substitutes Emi Nakajima and Mina Tanaka were on target to give former women's world champion Japan a 2-0 win at home to Switzerland in an international friendly on Sunday.
Nakajima broke the deadlock midway through the second half in torrential rain at Nagano U Stadium before Tanaka rounded off the win with virtually the last kick of the game.
"We weren't really able to up the tempo and play our aggressive style of attacking soccer but I am happy we won the game," said Japan coach Asako Takakura.
