How many Kanji symbols are used in Japan?

According to one of the most frequently used Kanji dictionary, it estimates to be roughly 50,000 Kanji characters. However, it is not necessary for even Japanese people to memorize all the Kanji characteres in the dictionary to lead a normal life. If you know approximately 2,000-3,000 Kanji characters, it is most likely that you can enjoy reading newspapers or magazines written in Japanese, though the knowledge of both Katakana and Hiragana is also required to fully understand what's written in them.
