CCPR/C/JPN/CO/5 page 3 The State party should establish an independent national human rights institution outside the Government, in accordance with the Paris Principles (General Assembly resolution 48/134, annex), with a broad mandate covering all international human rights standards accepted by the State party and with competence to consider and act on complaints of human rights violations by public authorities, and allocate adequate financial and human resources to the institution. 10. While taking note of the State party’s explanation that “public welfare” cannot be relied on as a ground for placing arbitrary restrictions on human rights, the Committee reiterates its concern that the concept of “public welfare” is vague and open-ended and may permit restrictions exceeding those permissible under the Covenant (art. 2). The State party should adopt legislation defining the concept of “public welfare” and specifying that any restrictions placed on the rights guaranteed in the Covenant on grounds of “public welfare” may not exceed those permissible under the Covenant. 11. The Committee reiterates its concern about discriminatory provisions in the Civil Code affecting women, such as the prohibition for women to remarry in the six months following divorce and the different age of marriage for men and women (art. 2 (1), 3, 23 (4) and 26). The State party should amend the Civil Code, with a view to eliminating the period during which women are prohibited from remarrying following divorce and harmonizing the minimum age of marriage for men and women. 12. The Committee notes with concern that, despite numerical targets for the representation of women in public offices, women hold only 18.2 per cent of the seats in the Diet and 1.7 per cent of Government posts at the level of directors of ministries, and that some of the numerical targets set in the 2008 programme for accelerating women’s social participation are extremely modest, such as the 5 per cent target for women’s representation in positions equivalent to directors of ministries by 2010 (art. 2 (1), 3, 25 and 26). The State party should intensify its efforts to achieve equitable representation of women and men in the National Diet and at the highest levels of the Government and in the public service, within the time frame set in the Second Basic Plan for Gender Equality adopted in 2005, by adopting special measures such as statutory quota and by reviewing numerical targets for women’s representation. 13. The Committee is concerned about reports that women hold only 10 per cent of management positions in private companies and earn on average only 51 per cent of men’s salaries, that women account for 70 per cent of informal workers and as such are excluded from benefits such as paid leave, maternity protection and family allowance, are vulnerable to sexual harassment owing to their unstable contractual situation, and that they are often forced to work as part-time workers to sustain family life (art. 2 (1), 3 and 26). The State party should take measures to promote the recruitment of women as formal workers and to eliminate the gender wage gap, including (a) require all companies to take positive action to ensure equal employment opportunities for women; (b) review any deregulation of labour standards resulting in longer working
