Translation guide
The English word "supervisor" can refer to a range of roles from a workplace manager to an academic advisor. In Japanese, the appropriate term depends heavily on the context—whether it's a company, school, part-time job, or research setting. Direct translations exist but are often too formal or specific; learners should choose based on the relationship and setting.

The English word "supervisor" is often used loosely for anyone who oversees your work. In Japanese, calling someone スーパーバイザー (supervisor in katakana) is rare and sounds like a specific job title in certain industries (e.g., retail). Stick to the context-appropriate terms above.
上司 is your hierarchical superior, while 先輩 is a senior colleague who may not have formal authority over you. In many Japanese workplaces, a 先輩 acts as a mentor and informal supervisor, but for official matters, use 上司.
