The reason: at Tol Plantation on New Britain on 4 February 1942, he had authorised the bayoneting to death of 160 Australian prisoners.
The prisoners were military and civilian escapees from the Japanese invasion of Rabaul. Tired, hungry and demoralised after nearly two weeks in the jungle, they had decided to surrender. A couple of men miraculously survived the slaughter, and escaped to tell the story.
The Colonel, according to his peculiar code, was a man of honour. For him there was only one possible course: suicide.
He could not commit hara-kiri because his samurai sword had been confiscated by the Allies.
Death by drowning or jumping in front of a train would be improper. So he decided to end his life by starvation and exposure in the sub-zero weather.
While Allied authorities hunted him, Kusunose went to the foot of Fujiyama, to a deserted army barracks where he had soldiered as a youth.
He sat down facing the great mountain, which rose so steeply above him he had to bend his head back to see the splendor of the sunlit, snowcapped summit.
Kusunose sat down on December 9. On December 17 or 18, Death, which had been creeping nearer for nine days, sat down beside him.
As he sat dying, Kusunose covered 15 pages of his small black Japanese army notebooks with entries. He had been a soldier; he was dying as a soldier. The last entries concerned food and hunger.
On the last two days, he mentioned pains in his stomach and legs. His last entry was scrawled in red crayon: “Heaven will preserve Japan and the Emperor.”
When an Allied search party reached the barracks at the foot of Fujiyama, they found an old straw sandal, a chopstick and a rusty can. (Japanese lacking Kusunose's peculiar sense of honour had long since looted everything else.
The searchers also found Kusunose's body. But it no longer faced the sacred mountain. Before he died, Kusunose had found the strength to turn away. The diary explained why: “It would be disrespectful if I died in the presence of revered Fuji.”
Kusunose's left eye had been eaten away by rats.
