副大臣 (Senior Vice-Minister) is a political appointee ranking just below the minister. 政務官 (Parliamentary Vice-Minister) is a lower political appointee. 事務次官 (Administrative Vice-Minister) is the top career bureaucrat. In English, all three may be called 'deputy minister' depending on context, but 副大臣 is the most direct equivalent.
When translating 'deputy minister' into Japanese, consider the specific ministry and the nature of the role (political vs. bureaucratic). If unsure, 副大臣 is the safest choice for a political deputy.
