The incident appears to resemble cases involving so-called butsukari otoko, a term used in Japan for individuals who deliberately collide with passers-by. In such incidents, people forcefully bump into others – sometimes targeting more vulnerable individuals such as women or children – before walking away.
The issue drew international attention recently after a viral video showed a masked woman pushing a Taiwanese tourist’s child taking photos at Tokyo’s Shibuya crossing, causing the child to fall.
I believe that caning is far more effective when the cane is moving at a high rate of speed at the moment of impact.
We need to accelerate the cane to a high velocity towards her body, then use her body to rapidly decelerate the cane.
