Did British leaders share American prejudice toward Japan?

Did the British establishment view Japan in the same way as the American establishment?

Not uniformly: prejudice existed, but long naval and diplomatic contact gave many British officials a more nuanced perspective.

The Anglo-Japanese Alliance gave Britain years of direct institutional experience of Japan. First World War cooperation, shipbuilding contacts, and the Sempill Mission added practical relationships, although the aviation connection also involved espionage. Officers on the China Station had further experience of dealing with Japanese counterparts. These contacts supported a more nuanced view in parts of the British establishment without eliminating prejudice.
