Loved this episode. The fact it had a Japanese theme is somewhat irrelevant. Take out the politics and it is a wonderful character study. The real issue is how rumor and innuendo can cause fear and distrust among friends and neighbors within a community. Similar theme to the 1960 Twilight Zone Episode, The Monsters are Due on Maple Street. You could take this theme and place it anywhere at any point in time and it would still be relevant.
I also loved the fact it had 4 veterans of the old Charlie Chan movies: Philip Ahn from 1938's Charlie Chan in Honolulu; Key Luke, who was son Lee Chan in the 1930's; Benson Fong, who was son Tommy Chan in the 1940's, and Victor Sen Yung, who was son Jimmy Chan in the 1940's. It was wonderful seeing them all together.
