The List of Japanese ambassadors to Portugal started when Kasama Akio presented his credentials to the Portuguese government in 1932.
Japan and Portugal established diplomatic relations in 1860, but Japanese ministers to France and Spain concurrently served as minister to Portugal. The Japanese legation was opened in Lisbon in 1932.
This is a chronological list of Japanese diplomats.[1] [2]
