Background

The Senju are one of the Land of Fire’s two foremost ninja clans, alongside the Uchiha. Their feud has endured for centuries, possibly millennia, and repeatedly draws both clans and their allies into large-scale warfare. 11 39

During Madara and Hashirama’s childhood, Butsuma Senju confronted Uchiha Tajima at the river separating their territories. The encounter exposed the hostility surrounding their heirs’ private friendship and escalated immediately into combat. 3 4

After Butsuma’s death, Hashirama became clan head while still young. During the following two years, the Senju reconciled with the Uzumaki Clan, began intermarrying with them, and increased their population by approximately one-third. 13

Hashirama’s repeated attempts to negotiate peace with Madara fail because neither clan can accept the losses inflicted by the other. Madara ultimately declares war, using the Uchiha Clan’s newfound funds to sustain a prolonged campaign against the Senju. 44 45

Clan Characteristics

Chakra Reserves and Vitality

Senju ninja are noted for unusually great chakra reserves and tenacious life force rather than a universally shared Kekkei Genkai. Their resilience lets them endure combat that would incapacitate many other shinobi. 17 46

• Senju fighters are commonly associated with Water Release and Earth Release techniques. 16
• Their endurance is a major reason the clan has been able to contend with the Uchiha for generations. 20
• The clan fields conventional ninja forces rather than relying on a single shared bloodline ability. 46

Hashirama’s Wood Release

Hashirama’s Wood Release is an exceptional power within the clan and its greatest battlefield asset. He can produce wood constructs without hand seals and has continually expanded the technique’s scale. 17 20

• Wood Release: Deep Forest Emergence — Creates a massive forest across the battlefield. 20
• Wood Golem and Wood Dragon — Powerful constructs used to restrain Madara’s Susanoo. 50
• Wood Clone and Flower Tree World Advent — A clone-assisted technique that transforms much of the battlefield into a flower-filled forest. 50
• Hashirama’s immense chakra reserves give him a major advantage in extended combat, even against Madara. 22 50

Allies and Enemies

• Uchiha Clan — The Senju’s hereditary enemy. Hashirama seeks reconciliation, but Madara and much of the Uchiha reject peace and pursue war. 18 44 45
• Uzumaki Clan — Close allies who reconciled and intermarried with the Senju. Uzumaki ninja reinforce the Senju in war and sacrifice themselves to help Tobirama escape. 13 46 50
• Sarutobi Clan — A Senju-aligned force that contributes more than eighty ninja to the major war. 46
• Shimura Clan — Senju-side allies who participate in a distant, support-oriented role during the war. 46 47
• Hyuga Clan — Expected by many to favor the Senju because of their reputation, but the Hyuga Branch Family instead joins the Uchiha alliance and attacks Senju forces. 38 49

Story Role

Conflict with the Uchiha

The Senju and Uchiha repeatedly fight without decisive results while their leaders and heirs confront one another directly. Madara and Hashirama are initially evenly matched, while Tobirama survives coordinated attacks from Izuna and Jobu through tactical use of Steel Wire and Body Flicker. 4

As the conflict worsens, Tobirama treats eliminating Uchiha fighters as a practical solution to the clans’ rivalry. His destruction of Izuna’s returned Sharingan triggers Madara’s unstable Mangekyō Sharingan awakening and escalates the war further. 19 22 23

Hashirama’s Peace Proposal

Hashirama believes that the Uchiha and Senju can create a village where clans and civilians live without fear of war. He argues that reconciliation between their clans could inspire others throughout the Ninja World to do the same. 44

“As long as we can put aside the hatred between the Senju Clan and Uchiha Clan, the other ninja clans will see hope.” 44

Madara rejects the proposal as fantasy, arguing that clan duty, betrayal, and survival make lasting peace impossible. His refusal leads to the Uchiha’s renewed declaration of war. 44 45

Uchiha–Senju War

The Senju mobilize more than 400 of their own ninja, backed by roughly 100 Uzumaki, over 80 Sarutobi, more than 50 Shimura, and additional allied clans—around 700 fighters in total. 46

Although the Senju coalition outnumbers the Uchiha side, Hashirama is occupied fighting Madara while Uchiha forces, later reinforced by more than one hundred Hyuga Branch Family ninja, inflict severe losses. 46 49 50

Tobirama responds by ordering a defensive retreat rather than a futile counterattack. He judges that preserving the Senju army is essential while Hashirama and Madara’s duel determines the war’s outcome. 50
