Yamamoto (山本?) is a fictional character in the manga series Spriggan created by Hiroshi Takashige and Ryōji Minagawa. He is the head of the ARCAM Corporation's Japanese branch. He is also linked to be a former Spriggan operative himself in his younger days.


Head of ARCAM's Japanese headquarters, he took in Yu Ominae in his youth as a ward after he found out that he was an ex-COSMOS child soldier rescued by Oboro in South America. He then trained Yu in military and guerilla tactics in order to let him be activated as a Spriggan agent while being his handler. He was responsible for calling Rie Yamabishi back to Japan after learning that she was related to Yu Ominae due to their history.[2]

Yamamoto became more and more involved with the company when he fought against COSMOS soldiers from raiding the interior of ARCAM's Japanese headquarters. Later on, he was forced to work with Henry Garnum when he went to the South Pole with Rie Yamabishi and other ARCAM personnel so as to harness the power of the Fire Snake from the South Pole Shrine. At the last minute, he and the others turned on Henry Garnum and Larry Markson, defeating their forces stationed in Antarctica and quelling the Fire Snake before it went out of control.

Non-canon appearanceEdit

Yamamoto played a minor role in Spriggan: First Mission when he debriefed Yu Ominae on locating and securing the Megiddo Flame from the Machiner's Platoon.[3]


Since his days as the chairman of the ARCAM Corporation's Japanese branch, Yamamoto is a known smoker who would always make it a point to take a cigarette during his office hours.[4] Aside from this, he cares for Yu's welfare like he was his own son ever since he became his ward, always making sure that Yu was all right before and after a mission was completed.


At the end of the series, Yamamoto was shown firing a Browning BDA 9 pistol to take out the barrels and selector switches of several assault rifles and submachine guns belonging to the Trident Corporation.[5]
