Activists who took part in an anti-apartheid movement years ago in Japan, while voicing support for those oppressed in South Africa, are featured in newly released university archives.

Newsletters, photographs and other records compiled between 1963 and 2015, available at Tokyo's Rikkyo University, show how activists reached out to socially vulnerable people in Japan while protesting injustices happening overseas.

The archives, which are on display at the university's Research Center for Cooperative Civil Societies, are meant to shed light on the grass-roots effort against apartheid and other discriminatory practices.
