Land of Woods

The Land of Woods (林の国, Hayashi no Kuni) was once home to an Anbu group called the Prajñā Group. In the anime, Konohagakure once sent a team to meet with the Prajñā Group in an attempt to establish an alliance, but anticipating a betrayal on their part. The Prajñā Group did betray them, and were all but exterminated. Years later, in the manga, their remnants tried assassinating the Candidate Sixth Hokage, who had been the one to send the team that killed many of their shinobi, but failed and were killed.
