The Asia Rugby Championship, or ARC, is an annual rugby union competition held amongst national rugby sides within the Asia Rugby region. The competition was originally known as the Asian Rugby Football Tournament when founded in 1969, and was called the Asian Five Nations from 2008 to 2014.

The Japan national rugby union team, also known as the Cherry Blossoms, Brave Blossoms, or simply Sakura, is traditionally the strongest rugby union power in Asia and has enjoyed and endured mixed results against non-Asian teams over the years. Rugby union in Japan is administered by the Japan Rugby Football Union (JRFU), which was founded in 1926. They compete annually in the Pacific Nations Cup and previously in the Asia Rugby Championship. They have also participated in every Rugby World Cup since the tournament began in 1987.
