The News Agency of Nigeria (NAN) reports that the Nigerian senior women national football team could not keep up with the pace of the Japanese side in the game.
A string of brilliant saves by first choice goalkeeper Chiamaka Nnadozie kept Nigeria in the game in the first half.
But the Falcons almost took a surprise lead when defender Ashleigh Plumptre struck the woodwork from a free-kick.
Japan went on to score when Tanaka chested the ball from a free-kick and slammed past Nnadozie in the 65th minute.
Her second goal came three minutes later, from the penalty kick spot, after a harsh challenge from Osinachi Ohale on an advancing Japanese forward in the Nigeria area.
NAN reports that both teams used the game as part of their preparations for next year’s FIFA Women’s World Cup finals in Australia and New Zealand.
