I first time saw this game ,when I was 15. That's my first time went to Japen.Until last week I found this game's name,and history.
Lacross is a relatively popular team sport in the Americas, may have developed as early as AD 1100.Each team have 100 to 1000 plaryers on a field that stretched from about 500 meters to 3 kilometers long. These lacrosse games lasted from sunup to sundown for two to three days .
Nowadays, there are 3 different types of play about Field lacrosse(Men's lacross),Women's lacorsse,and Box lacrosse.It is the fastest growing sports in the world but it is in the Olympic Games appears only five times.
So,lacrosse has a long way to go in regards to being an Olympic Sport and being even recognized as an Olympic Sport. By the way, it has no universality yet as only Canada and the USA really play the sport at a high enough level.
