Nippon Professional Baseball (日本野球機構 Nippon Yakyū Kikō) 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 of 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 (大日本東京野球倶楽部 Dai-Nippon Tōkyō Yakyū Kurabu) in 1934 and the original Japanese Baseball League.
