Five Great Shinobi Countries

Fire Country

The Fire country is marked by forests, helping to give rise to its ninja village "hiding in its leaves". The Fire Country is one of the largest ninja countries in the Naruto world, sharing borders with more countries than any other. It borders Grass, Rain, Waterfall, Sound, River, Tea and several unnamed countries. The Fire Country is home to many cities, including Konohagakue no Sato, Tanzaku Gai, Otafuku Gai, Otakame Sato and Tokkuriji.

Water Country

The Water country is one of the smaller countries in the series, but it has a strong ninja force. This coupled with it being an island grants the country a great defense against outside threats. The greatest threats to the country seem to come from within, constant wars and strife has caused many citizens and ninja to turn against themselves and the country leadership.

Earth Country

The Earth country is one of the unrevealed lands in Naruto. A one shot picture of Deidara potentially revealed a village in the background; it was marked by earthen cliff dwellings. The Earth Country is one of the larger ninja countries in the Naruto world, sharing borders with Waterfall, Grass, Rain and several unnamed countries. Because of Hidden Rock's warlike tendencies against the Fire Country, their invasion path leads them through smaller countries like Grass.

Lightning Country

The Lightning country is one of the unrevealed lands in Naruto. The Lightning Country is one of the larger ninja countries in the Naruto world, but it only shares a border with one unknown country. The remainder of the country is marked by a long coastline.
