John Derbyshire (an Englishman) mentions two criminals executed in Japan despite the leftyish Justice Minister’s abolitionist stance, and says at the end:

Executions in Japan are by hanging: The Japanese at least understand that capital punishment is an act of state violence, not a medical procedure, as in the dishonest and despicable system of “lethal injection.”

The condemned prisoner also does not know the day of his execution. This is the same as the old French system, if I recall my Camus correctly. Amnesty International says this is cruel, but I’m not sure I agree.
