The 2011 J.League Division 1 season was the 46th season of professional football in Japan, and the 19th since the establishment of the J.League. The season began on March 5 and concluded on December 3. The season was put on hold from March 12 to April 23 due to the aftermath of the 2011 Tōhoku earthquake and tsunami, therefore canceling a planned five-week summer break between June 27–July 29 in order to allow preparation of the Japanese national team for the 2011 Copa América.
