Jorge Bustamante, U.N. special rapporteur on the rights of immigrants, has concluded his Japan visit and takes with him a sense that the government lacks a system to curb discrimination and better protect the human rights of foreigners.

Bustamante, on his first official fact-finding mission here, focused on the human rights situation of migrants and said he would submit a report to the U.N. Human Rights Council in September or October.

He spent more than a week in Tokyo; Nagoya; Toyota, Aichi Prefecture; and Hamamatsu, Shizuoka Prefecture; meeting with government officials as well as human rights organizations and various foreigners living in Japan.
