Here is an excerpt from the book Fall of Japan by William Craig,
After General Anami’s death, the Emperor had asked the senior officers to forget their personal feelings and devote themselves to the nation in the difficult days ahead.
His wife was shocked. For two days she brooded. A normally pleasant, even dispositioned lady, she usually radiated a genuine warmth to those around her. Plump and small, she reminded everyone of a smiling Buddha. But the women who greeted her husband when he came home on the night the 17th of August was far from even-tempered, She was almost hysterical as she berated him.
“When ae you going to commit suicide?” she asked in a shrill voice. The general looked closely at her. Here eyes were wide with excitement, her features flushed with anger. He was dumbfounded.
“I have a responsibility to the Emperor right now. I is important that I stay alive to serve him”
“It is more important that you atone for the surrender”, she cried.
The couple argued heatedly over the question of his death, and later went to bed in a strained atmosphere.
Each night thereafter the argument continued. After the servants had gone to bed, the women pressed her husband for an answer, and he put off the question. Neighbors noticed that Mrs. Sugiyama was becoming more distraught, more wild-eyed. She no longer smiled. She pouted in frustration.
On the seventh day, she confronted the general once more in his bedroom.
“When are you going to commit Hara-kiri?” she repeated.
After taking the officer’s tunic, the general had seated himself in a comfortable chair. Then he had pressed a service revolver to his white shirt and fired into his chest. Unlike Hideki Tojo, Sugiyama had found the mark and fallen unconscious.
Of course the Japanese of that era had a very strong code, death before dishonor. Still, it does seem odd for a wife to be goading her husband to commit suicide. I am not sure what to read into it. Comment at will
