As a Japanese interpreter, your job is to facilitate conversation and communication between a Japanese speaker and a speaker of another language. This job is usually English-Japanese translation, but there are openings for other languages as well. Success in this job requires deep familiarity with the meaning of phrases, a thorough understanding of Japanese culture and terminology, and the ability to provide simultaneous interpretation. Many Japanese interpreters also work with written text, formal documents, and other non-verbal types of communication. You are expected to translate things as faithfully and accurately as possible, and employers may test you on this part of the job.
