The 1966 Nippon Professional Baseball season was the 17th season of operation of Nippon Professional Baseball (NPB).
Nippon Professional Baseball or NPB is the highest level of baseball in Japan. Locally, it is often called Puro Yakyū (プロ野球), meaning Professional Baseball. Outside Japan, it is often just referred to as "Japanese baseball". The roots of the league can be traced back to the formation of the "Greater Japan Tokyo Baseball Club" in Tokyo, founded 1934 and the original circuit for the sport in the Empire two years later - Japanese Baseball League (1936-1949), and surprisingly even continued to play through the dark years of total warfare with Japan's invasion of Manchuria in 1931, and intervening in the Chinese Civil War in 1937 with the wider Sino-Japanese War (1937-1945), and into the greater World War II (1939-1945).
