According to Japanese law, after the death penalty is pronounced, there is a long appeal procedure. Jurors are generally reluctant to vote for the death penalty because the thought of possible misjudgment will bring them a very heavy psychological burden. Even if the death penalty is imposed, it must be executed by the Minister of Justice. Many ministers of justice refused to sign execution orders because of political views or other personal reasons. There was once a minister of justice who did not sign an execution order during his term of office. Therefore, there are very few cases of actual execution of the death penalty in Japan. Many people have been sentenced to death for 20 years, but they have not been executed yet.

There are also great differences in the understanding of law and morality between Chinese and Japanese people. Japanese people attach great importance to moral judgment, which has existed in Japanese society for a long time. However, the long-term judicial practice has accumulated a large number of precedents, which has gradually formed a certain understanding of criminal cases in Japanese society: that is, following precedents. Everyone can master criminal law and criminal law precedents, and the judicial examination repeats these questions every year. Lawyers and defenders have a * * knowledge of the trial results, which will not be much different from expectations.

The Japanese public's expectation of a big turning point in the trial results is low, and actions like signature appeal are "unrealistic" for the Japanese, so they don't get much response. Japanese media reports are based on a high understanding of the law first, and will not make large-scale and high-density reports before the judgment. Generally, suspects will not be required to be sentenced to heavy sentences.
