James Whitinui Joseph is a New Zealand-born Japanese former rugby union player and current rugby union coach. A flanker, Joseph represented Otago at a provincial level, and was a member of the New Zealand national side, the All Blacks, from 1992 to 1995, before representing Japan in 1999. Joseph, now head coach of the Japanese national side, has coached since his retirement, coming through the ranks in New Zealand before his first national stint.

The Japan national rugby union team, often a.k.a “Cherry Blossoms”, or a.k.a “Sakura”, and more a.k.a “The Brave Blossoms” 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.
