|(うちはタジマ, Uchiha Tajima)|
|Appears in||Manga only|
Initially a father of five sons, Tajima lost three of them in battle against the Senju, and was left with Izuna and Madara at the time of his introduction. He made an appearance on the battlefield alongside his son Izuna after finding out that his other son Madara was meeting with Hashirama Senju on a regular basis. Thinking along the same basis as his nemesis Butsuma Senju, he and Izuna attempted to take advantage of Madara's meeting with Hashirama to eliminate another Senju. When he was greeted by Butsuma and Tobirama Senju, the Uchiha noted that they thought along the same lines as he prepared to draw his sword.
Tajima tried to attack Tobirama, intending to use his death to shake Butsuma's resolve, so that he could gain an advantage over him, but his attack was foiled by Hashirama. After Madara admits to being weaker than Hashirama when Tajima asked his son whether or not he was ready to join the fray, the Uchiha reluctantly retreat, and though he was not able to gather any intel on the Senju in this endeavour, Tajima was pleased nonetheless that this situation had allowed Madara to awaken his Sharingan.
Tajima had dark-coloured eyes as well as dark-coloured hair which framed a gaunt-looking face further accentuated by his mouth which naturally curled upwards. Attire-wise, he wore a standard black attire, with a high collar and the traditional armour of that time along with foot wraps, sandals and a tantō strapped horizontally to his back.
A wielder of the Sharingan, Tajima was blessed with the various advantageous abilities of the eyes which greatly enhanced his own combat prowess on the battlefield, enough that he was noted to be evenly matched with his rival Butsuma Senju. He also carried a tantō strapped to his lower back, indicating that he was a practitioner of kenjutsu.
- Tajima may have been named after Gochi-in no Tajima (五智院 但馬), a famous warrior monk who fought the Battle of Uji in 1180.
