Kusa no Kuni

The Grass country contains some of the more widely varried landscapes in the series, with forests, grasslands, mountains, rivers and bamboo thickets dotting it. The country shares borders with Earth, Fire, Rain and Waterfall. Because the country lies between Earth and Fire, it has been in invaded by the Earth Country during previous ninja wars. To avoid Earth gaining a foothold next to the Fire Country border, many Leaf ninja came to Hidden Grass's aid during the war. This resulted in many skimishes taking place within its borders.
