Apimac has released a Japanese-English translation dictionary for Mac OS X. Downloadable now, it costs $24.95 to register.
The dictionary provides grammatical notes with thousands of Japanese words and phrases with English translation. You can copy words from the dictionary and paste them into other application documents; you can also use the dictionary to help you study grammar.
Apimac said that English translations include information about whether a word is a non, adjective or verb; the dictionary will display dozens of Japanese adjectival nouns or quasi-adjective entries with their English translations.
System requirements call for Mac OS X v10.2 or later. It’s a Universal binary.
