Declan's Japanese FlashCards is a fully configurable audio-based Japanese vocabulary flash-card program. The program has been designed to help students learn a large number of Japanese words as quickly as possible in a systematic but fun and simple way.

The program incorporates an audio feature that uses a native speaker's voice recordings of a word's pronunciation to aid the learning process. Word Files comprising over 4000 of the most frequently used Japanese words, each with a native speaker's voice recording of its pronunciation, are available for free download.

To be able to access more than three Word Files and Words Files of greater than 40 words, the program needs to be registered.
