[1] Like its able-bodied counterpart, the Pan Pacific Swimming Championships, the meet is staged to allow for an international championship-level meet in the non-Paralympic and non-World Championship years.
Like the Pan Pacific Swimming Championships, the meet was founded by its four Charter nations: Australia, Canada, Japan, and the United States.
As part of the Charter, hosting of the meet is to rotate among these four nations, with the exception to the requirement of the meet being held in Japan every other championship.
Due to the presence of swimming power-house nationals like the United States and Australia, it is regularly used as a staging meet for the Paralympics and World Championships.
