General Japanese documents consist of about 2,000 characters based on Joyo Kanji, of which 1,000 characters are frequently used. We categorized those 2,000 Kanji into 3 levels based on how often used.
Level 1 555 characters Very frequently used
Level 2 555 characters Frequently used
Level 3 890 characters Less frequently used compared to the above 2 levels

According to our research 60% - 70% of Kanji that appear in newspaper and magazine articles or general business documents are covered by Level 1 Kanji. With 555 characters of Level 2 added, they cover over 90% of Kanji that appear in general documents overall.
Learning those 1,110 characters with priority is the most efficient way of Kanji learning.

Based on the research CosCom developed a unique Kanji material, Audio e-Book 2001.Kanji.Odyssey.
