Based on the gender discrimination in Japan, we had found some problems including unfair towards women. In perspectives of men, they just only tools that must obey to the rules.
Discrimination is an assault on the very notion of human rights. Discrimination is the systematic denial of certain peoples' or groups' full human rights because of who they are or what they believe. It is all too easy to deny a person’s human rights if you consider them as “less than human”.
This is why international human rights law is grounded in the principle of non-discrimination.
The drafters of the Universal Declaration of Human Rights stated explicitly that they considered non-discrimination to be the basis of the Declaration. Yet discrimination due to factors such as race, ethnicity, nationality, class, religion or belief, sex, sexual orientation, gender identity, age or health status – or a combination of factors – persists in many forms in every country in the world.
Discrimination in law enforcement can mean that certain groups are viewed by the authorities as ''potential criminals'' and so are more likely to be arrested and imprisoned. It can also mean that they are more likely to suffer harsher treatment, possibly amounting to torture or other forms of ill-treatment, once in criminal justice system.
An individual’s identity or status may also affect the nature and consequences of their ill-treatment – for example, transgender women detained with male prisoners are particularly at risk of rape and other forms of sexual violence.Many individuals face discrimination based on more than one element of their identity – for example, Indigenous women face discrimination not only as women, but as Indigenous Peoples. Such multiple factors interact and change individuals’ experience of discrimination.
Violence is used to terrorize women in the home, at work, in custody and in conflict, where rape is often used as a “weapon of war”. Wherever it is inflicted, this violence is intimately linked to women's subordinate position in society and restrictions on women’s autonomy. Sometimes state officials perpetrate violence. Often they are complicit in the violence of others who may be employers, religious or customary authorities or family members.
Dozens of countries still have laws which criminalize homosexuality. Such discriminatory laws not only deprive a sector of the population of their human rights, they may also act as a license to torture or ill-treat those detained. By institutionalizing discrimination such laws can act as an official incitement to violence against lesbian, gay, bisexual and transgender people in the community as a whole. However, such concerns are not limited to countries where homosexuality is illegal. Institutionalized prejudice means that lesbians, bisexuals, gay men and transgender people who come into contact with the law for other reasons may be targeted for abuse.
