Several countries have either official or unofficial national sports. Many countries have a traditional or official national sport that differs from the one that is currently the most popular. Other countries have no clear national sport, with many that are popular.
Canada - lacrosse is the official summer sport and ice hockey is the offical winter sport, but hockey is by far the sport most closely followed, and most closely linked to national pride.
Japan - sumo wrestling is traditionally viewed as Japan's national sport, but baseball is today more popular, and football is rapidly increasing in popularity
Korea - Tae kwon do, but StarCraft has sometimes sarcastically been refered to as the national sport
Pakistan - field hockey is the official sport (winners of the Gold in 1971,1978, 1982 and 1994), but cricket is the most popular (winners of the world cup in 1992)
