Example http://jisho.org/words?jap=%E6%97%A5%E6%9C%AC&eng=...

you will learn that 日本 is pronounced Nihon (にほん)

if you click on Kanji details, it shows you how to write it .

example: http://jisho.org/kanji/details/%E6%97%A5%E6%9C%AC

1. Japanese learn Toyou Kanji which is about 1865 Kanji used in everyday life. Most Japanese because of mobile phones and computers forget how to write but they can read and understand a majority of them.

2. When you study most Japanese books each Kanji will come with the on-yomi and Kun-yomi for each kanji. The on-yomi or Japanese reading is used for parts of adjectives, beginnings of verbs

e.g. the Kanji for eat is 食べる　or taberu. The onyomi is た（べる）as its a verb. The various endings will change while the root remains the same.

If its a noun it will be joined with other Kanji to form words etc and is pronounced しょく

食事　（しょくじ）　＝meal

定食　（ていしょく）　＝set lunch etc

This is the Kun-yomi at work. Some Kanji have multiple readings but you can usually tell what they are by the endings.
