The Japanese to English Dictionary is written in java, and so will require that you have the JRE installed prior to its installation & use. It is a hobbyist project of mine intended to address my admittedly narrow needs, and so will fall short of yours. If you have any suggestions for improvements, please let me know!
This open source application would not be possible without the Japanese-English dictionary and kanji files assembled by Jim Breen; it would also have taken a great deal...
