Arsenal Ladies have signed Japan internationals Shinobu Ohno and Yukari Kinga.
Ohno, 30, has moved from two-time Women's Champions League winners Lyon while Kinga, 29, joins from Japanese side INAC Kobe.
The pair helped Japan win the World Cup in Germany in 2011, and were Olympic silver medallists at London 2012.
"They will add real quality to our squad," said Arsenal Ladies general manager Vic Akers.
"They are both extremely experienced internationals, who are proven at the very top level."
Ohno has made 116 appearances for Japan, while Kinga has been capped 87 times.
The Women's Super League, which will split into two divisions for the first time this season, gets under way in March.
