Seemingly stemming from his age and experience, Ittan is a calm and collected individual. This is seen both when he reminded his team-mate Zaji not to get overly confident because they were at war and his quick thinking while under enemy attack.
Ittan has light-coloured, spiky hair and a dark-coloured beard (both of which are depicted as brown in the anime). He wears the standard Iwagakure shinobi outfit complete with his right sleeve missing as well as the forehead protector of the Allied Shinobi Forces.
Ittan could be considered a skilled shinobi to have been put in the Surprise Attack Division under Kankurō's command. Ittan can use earth element techniques, and can use them to make trenches, allow area's of the earth to rise or fall, or create a dome of earth to protect himself as well as others. Ittan also showcases himself to be a well-experienced shinobi as shown by reminding Zaji not to be too confident of himself.
Shinobi World War Arc
Ittan was assigned to the Surprise Attack Division of the Allied Shinobi Forces. In the anime, he was one of the shinobi who got into fights with people from other villages, Ittan himself getting into an argument with Kiri, who said that Iwa-nin couldn't be trusted. They are however able to set their differences aside and work together after hearing Gaara's speech.
Shortly after he and his team-mates had set up camp where Ittan was designated to create several trenches around the location, they were ambushed by Akatsuki's Surprise Attack and Diversion Platoon.
From Hoheto Hyūga's description he was able to recognise Deidara's explosive clay. He quickly used his Earth Release technique to transport his team-mates to safety by sinking the entire area where they had set up camp. During the battle between the two ambush squads, on Kankurō's orders, Ittan raised the part of the earth he had previously sunk sending Sasori crashing into the rising surface. He also used his ability to create a dome to protect the injured and Kiri while he was healing them.
Later he and the part of his division encountered a back up for the Surprise Attack and Diversion Platoon. When they tried to flee from them, they are hit with Ibuse's Poison Mist and soon succumb to its paralysing effects. They are however rescued by Mifune and the samurai of the Fifth Division who carry them to the Logistical Support and Medical Division for treatment.
