The ITF announced on 21 March that, due to the devastating earthquake and tsunami in Japan, this tie would be postponed until 16-17 July.
“In light of these dreadful and exceptional circumstances, we felt it was important to give the JTA the opportunity still to host the tie and for Fed Cup to play its very small part in the healing process of a nation. We are grateful to both nations, Japan and Argentina, for their cooperation," said ITF President Francesco Ricci Bitti.
Argentina is looking to win a fourth consecutive tie against Japan. The two nations are level with three wins each in previous match-ups, but it is the South American side which has had the best of recent clashes.
Both nations earned their place in the World Group II play-offs following successful zonal campaigns. Argentina is looking to bounce straight back into World Group II after being relegated by Canada at the same stage of the competition last year.
Japan dropped out of World Group II in 2009 and failed to earn immediate promotion after losing to Slovenia in last year’s World Group II play-offs.
