During World War II, Kaslo became home to approximately 1100 Japanese Canadians. Seventy-eight people lived in the Langham building. The Japanese Canadians lost lives, homes, businesses and peace of mind with their internment to Kaslo and other "ghost towns". Families were broken apart and tight knit communities were cast to the winds of an unjust fate. The real story is the remarkable strength with which these people picked up the pieces, turning frustration and sorrow into new and honourable lives.

A portion of the third floor has been restored to circa 1941 thus forming an archival display representing the period of time during WW II when the building was used as an internment center for people of Japanese descent. The display includes artifacts, photographs, and story-boards. The focal point of the Museum is a room once occupied by the Konno family.
