Isonokami no Yakatsugu's Nara periodUntei (芸亭) is held out to be Japan's first public library, but private libraries, such as Kanazawa Bunko, remained the norm until modern times. The Imperial Library, one of the predecessors to the National Diet Library, was established towards the end of the nineteenth century. In 1948, during the Occupation, the National Diet Library Act (ja) was passed, creating Japan's sole national library,[1] followed in 1950 by the Library Act (ja), the twenty nine articles of which cover both public libraries (公立図書館) (Chapter II) and private libraries (私立図書館) (Chapter III).[2]
As of 2008, there were 3,106 public libraries in Japan, including: 1 regional library, 62 prefectural libraries, 2,433 city libraries, and 610 town libraries.[1]
