One Second Japanese 1600 Complete Version

This application lets you memorize the Japanese words every seconds with voice. The difficulty of the Japanese words in the application is about the same as an entrance examination for a Japanese university. The book "One Minute English Words" for Japanese is million seller in Japan.

The words in :
the RED files : You will understand immediately.
the GREEN files : You will understand within three seconds.
the YELLOW files : You probably have ever seen before but cant remember the meaning.
the BLUE files : You have never seen or heard them before.

If the exam is coming tomorrow, you can study the words in RED files. If you practice everyday, do GREEN and Yellow files, not BLUE files. It takes a lot of minutes to memorize BLUE files.
The easiest method to raise your result is to memorize the word in your faint memory perfectly.
