Readers of these historical materials will encounter derogatory references to Japanese Canadians and euphemisms used to obscure the intent and impacts of the internment and dispossession. While these are important realities of the history, the Landscapes of Injustice Research Collective urges users to carefully consider their own terminological choices in writing and speaking about this topic today as we confront past injustice.
