Font Display
Most programs (such as Kmail, Firefox, etc) will typically display only Kana (the syllabic Japanese scripts). However, Kanji characters will display as small boxes with characters/numbers inside.
To read and see Kanji, Use Synaptic to install ttf-kochi-mincho-naga10 and restart your program.
For even more options, search Synaptic and install any of the other "ttf-kochi" or "ttf-sazanami" fonts
Fonts for PDF Files
Using Synaptic, install xpdf-japanese for Japanese font support in pdf files.
Study
Kanatest is a simple Japanese kana flashcard program for the study of hiragana and/or katakana.
It can be installed via Synaptic. You also need to install the Japanese fonts mentioned in the Display section above. Once installed, Kanatest can be started by going to Kmenu >>> Education >>> Languages.
