Japanese document review jobs exist in a variety of fields, but you can find the most opportunities in legal services or on staff with an attorney. Your duties in this career primarily cover written documents that you translate from Japanese to English or vice versa. The gravity of the position means that you must be fluent in both Japanese and English and understand the nuances and references of both cultures. Opportunities are also available in judiciary systems and detention facilities. If you do document review as a lawyer, you can either work in your own practice or as part of a team with a law firm.
