Japan may have a low homicide rate but the infanticide rate seems to be increasing due to low wages causing households to have weak purchasing power. All this is caused by the weak yen and the fact that companies are underpaying their employees. This evil woman seemed to have suffered from stress probably originating from her own personality issues but also falling wages, low household income and poor relations with the husband.

Racist Japanese politicians as usual.

As a westerner, I have actually stopped buying Japanese products. My new car is a 2015 Hyundai Genesis 3.8L AWD. My new phone is an iPhone 6.

I'm very disappointed and angry at Japan's nationalistic nature.

She most likely suffered irreversible brain damage due to air embolism. I'm a medical doctor and nearly all cases of air embolism in the brain have resulted in severe, debilitating disabilities, such as inability to walk, lack of touch/vibration sensation and lack of speech. It depends on which cerebral artery the embolus occluded, however in this case, it is most likely the anterior or middle cerebral arteries and/or branches of them. This would have resulted in a huge infarct over a vast area if thrombolytics weren't given (and most likely they weren't). Her frontal and/or temporal lobes are most likely irreversibly damaged.

She most likely suffered irreversible brain damage due to air embolism. Some of you are treating this as if it's just a minor case like not being able to breathe or minor oxygen deprivation. Air embolisms can cause infarcts over a vast area of brain tissue. Her not being able to talk may mean that the frontal and temporal lobes may be affected.

She's just another psychopath, nothing to do with her being Japanese.

Lock her up for life.
