Tomitaro Horii was born in Hyogo prefecture, Japan.
He graduated from the Japanese military academy in 1911 and became an infantry officer.
During the First Battle of Shanghai in 1932, he was assigned to the headquarters of the Shanghai Expeditionary Army. He commanded the 55th Infantry Group, later renamed the South Seas Force, beginning in 1941, with which group he participated in many landings during Japan's southward expansion.
During the New Guinea campaign, Major General Horii achieved the impossible by leading a column of 8,500 men of the 144th Regiment across the Kokoda Trail over the treacherous Owen Stanley mountain range. Even though he achieved surprised and initially drove back the Australian defenders, logistics across the trail broke down, and his troops began to fight on empty stomachs. Mainly because of a change in the overall war situation, Horii was ordered to fall back onto the trail, marching all remaining soldiers back across the Owen Stanley for Buna on the northern coast. He knew it was no easy task to cross the trail once again, but the food situation rendered him without choice even if he did not receive the order to fall back. En route, Horii took a misstep while crossing the Kumusi River and drowned.
