At the end of January 2011, AFC sent a letter to FIFA asking them to change the dates for the 2013 Confederations Cup as it would clash with an official FIFA match date - June 18.
“We request the FIFA Confederations Cup – Brazil 2013 to be scheduled in another period of time that does not clash with the FIFA Official Match Dates already confirmed by FIFA and applied to respective Competition Calendars of different Confederations including AFC,” AFC wrote in a letter to FIFA.
The June 18, 2013 Asian qualifiers is a crucial fourth-round match and is the home stretch for teams looking to book their places in the 2014 FIFA World Cup finals.
Today, AFC came to their senses and announced they will make sure Japan won't have to play on June 18, 2013.
It was also decided to place Japan in position 5 of their group for the 2014 FIFA World Cup qualifiers (final round-Asia) to avert a clash with the 2013 FIFA Confederations Cup (June 16-30). Now Japan will have a rest day on June 18 in the FIFA World Cup qualifiers (final round-Asia) that will enable the Asian champions to play in the FIFA Confederations Cup.
