Iga Region

Iga Region (伊賀地域 Iga Chiiki,) often simply referred to as Iga (伊賀 Iga,) is an island situated within the first half of the Grand Line, bordering the edge of one of the sea current's Calm Belts. As a result, much like Water 7, this makes travel to and from Iga Region hazardous. Unlike Water 7, Iga has much more sea king activity than most islands.

Iga is famed for its ninja. It has a deep seated history of raising highly skilled ninja and for being painstakingly secretive about the knowledge its masters pass down to their students. Many of Iga's ninja are typically raised to work as mercenary spies and assassins for nearly any group or organization willing to pay for their services. As such, they can be found amongst the ranks of the World Government, Revolutionary Army, various criminal syndicates and crews, and so forth. As a result, Iga has no natural affiliation with anyone besides itself, making for a very dubious presence in the world. However, they also still make for highly reliable allies and assets, as a considerable amount of ninja who hail from Iga are highly adept in espionage; some even showing the talent for killing the sea kings that swim along the island's coasts.

It is said that Iga Region's inhabitants view those from Wano Country as their natural born rivals, due to Iga's ninja greatly disliking the attitude that many of Wano's citizens uphold. Likewise, Wano seems to dislike Iga's citizens due to a lack of honor in their work. Thus, rarely do ninja and samurai ever get along.
