I have studied japanese language for past two and a half years at a university. I dont have any japanese friends so don't get much opportunities to speak. I would like to improve my overall japanese language skills speacially spoken. As i am fluent in day to day conversation in japanese, but want to improve on a broad range of topics (business, technical terminology etc). Please suggest some good websites where i can get online speacialized dictionaries in Japanese to English and vice versa.
