Article 1 of Japan's Lawyers Law stipulates that lawyers have two major missions: one is to support basic human rights and realize social justice; The second is to maintain social order and improve the legal system on the basis of performing duties honestly. Since World War II, Japanese lawyers have done a lot of work to accomplish the above mission. First, they initiated and organized the "Human Rights Publicity Conference". So far, the association has held more than 20 congresses. Secondly, Japanese lawyers are also extremely sensitive to public hazards and drug harm, and they have waged an indomitable struggle against these public hazards and won some victories. Third, Japanese lawyers have done a lot of work in improving the legal system, such as legislation on minors. Because of the lawyer's opposition, the legislative intention of dealing with juvenile criminal cases severely has not been realized. These actions by lawyers have won considerable support from Japanese nationals.
The responsibilities of lawyers stipulated in the Lawyers Law mainly include: participating in litigation cases, representing citizens, institutions and groups, and defending criminal defendants; Providing legal aid for non-litigation cases to the society; Acting for tax, etc.
