(NOTE: This kanji page is an ongoing project to help me study, which means there could be mistakes though I try not to make them.)

The best advice I've received about learning kanji is from a Chinese friend who had the highest score in her class on the Japanese Language Proficiency Test. She said children learned the characters by creating stories for each of them, which is one way you can view mnemonics.

• Readings in capital letters = ON-YOMI (Chinese readings; Sino-Japanese pronunciation)
• Other readings = kun-yomi (Japanese readings; indigenous Japanese pronunciation)
