NPB
Extracted from the Wikipedia article Nippon Professional Baseball.
NPB consists of twelve teams divided equally in two leagues, the Central League and the Pacific League, a format which it has largely kept since 1957. It has seen several waves of expansion and contraction, sometimes at the same time, to keep it at those numbers; most recently, in 2005, the Osaka Kintetsu Buffaloes merged with the Orix BlueWave to form the Orix Buffaloes, while the Rakuten Golden Eagles were added as an expansion team. As is common in Asian baseball (and unlike North American leagues), teams are generally named after their corporate owners, such as Yomiuri and Softbank. NPB also oversees two affiliated minor leagues, the Western League and the Eastern League.
