|This is the article on a shinobi from Otogakure. For a Konoha shinobi, head to Iwana Akame.|
|OVA||Naruto: The Cross Roads|
Like most petty villains Iwana thought that he was very powerful when in actuality he wasn't. He was very loyal to Orochimaru. Iwana also had a perverted side, getting a nosebleed from watching Naruto's Harem Technique, and he was also short-tempered, as he vowed to kill Naruto for it.
He wore a green-coloured shark-like top complete with a hood which resembled a shark's head, with an appendage on the back that resembled a dorsal fin and dark pants. He also had black-coloured eyes and two purple markings under each eye. He carried a giant shuriken on his back.
Iwana could use Hiding with Camouflage Technique enabling him to manipulate light around himself with his chakra in order to become invisible. He was also skilled in the use of some types of weapons and taijutsu.
Kajika and his group attacked Naruto Uzumaki, Sakura Haruno and Sasuke Uchiha while they were waiting for Kakashi Hatake to finish his reconnaissance for the missing man Genmai who was kidnapped to lure Team 7 and mostly Sasuke. Kajika kidnapped Sakura and took her to his lair while he and Yamame fought Naruto and Sasuke. The two returned, only they that were revealed to be Naruto and Sasuke in disguise, and had begun fighting against their leader. What had happened to Iwana was yet unknown.
- Iwana (岩魚、鮇) refers to several species of fish from the Salvelinus genus, known as char (or charr) in English.
