Japan should ensure that its school textbooks and other teaching materials present issues in "a fair and balanced manner," a United Nations human rights committee said in a report released Friday.

The U.N. Committee on Economic, Social and Cultural Rights issued the call in a report evaluating Japan's record on human rights.

The report listed 23 areas of "concern" on human rights issues in Japan, including discrimination against Koreans and other ethnic minorities, gender inequality in the workplace and "excessive" working hours.

The U.N. committee, established under the International Covenant on Economic, Social and Cultural Rights, urged the Japanese government to set up a human rights assessment system and ensure that Japan's domestic laws reflect the human rights provisions Japan has committed to observe.
