While the Joyo standards describe approximately 2000 common use kanji, used for government documents and taught in school “the number of different kanji employed in newspapers and magazines in general is approximately 3200-3300” (Daniels and Bright, 1996, 210). Furthermore Omniglot describes between 5000-10000 kanji used in Japanese writing, the number is most likely higher if one were to account for every possible usage of kanji, for the reason of variability “Number of Glyphs” is said to be 2000.
