The annual salary figure on a Japanese job posting (求人票) is an easy default for judging whether a job is good, but salary is just one variable in the overall picture of compensation and workload. Two postings that both say "annual salary ¥5,000,000" can involve completely different actual hours, overtime intensity, and scope of responsibility. Here are 6 things postings tend to leave out that directly affect what the job is actually like.
Of that ¥5,000,000 annual figure, how much is base pay (fixed monthly salary × 12 + bonus) and how much is overtime pay bundled in ahead of time (fixed overtime pay)? Postings don't always spell this out — you need to confirm it directly during the interview or before accepting an offer. For the same total figure, the higher the base pay portion, the more stable that income actually is; if a significant chunk is fixed overtime pay, the number already assumes you'll be working a certain amount of overtime.
If the salary structure includes fixed overtime pay, confirm exactly how many hours of "deemed overtime" (みなし残業) that corresponds to, and whether the company pays extra once you go over that. This detail is rarely displayed prominently in the posting — you need to ask directly in the interview. See the companion article on fixed overtime pay for more on how to approach this.
Many companies apply different pay or employment terms during the probation period (usually 3–6 months) — some even hire you as a contract employee (契約社員) during probation, converting to full employee (正社員) status only afterward. If the posting only lists post-conversion terms, confirm directly what the probation-period conditions are and what the standard is for becoming a full employee.
If the company has multiple offices or nationwide operations, confirm whether the role carries a possibility of forced relocation and whether you can decline it. For anyone on a specific visa status or with family settled in a particular city, this detail is easy to overlook but has major consequences. Relocation terms are usually spelled out in the employment contract, but you should ask about it while you're still at the job-posting stage.
A posting that says "average overtime around 20 hours/month" may not match what a specific team actually experiences, especially during busy seasons or for particular roles. If you get a chance to talk with your future direct manager or future colleagues during the interview process, politely asking about the team's real overtime patterns and busy periods is far more useful than the headline number.
A high salary paired with an opaque evaluation system and unclear promotion path isn't necessarily the better long-term choice. You can ask in the interview what cycle and criteria evaluations run on, and whether there's an example of someone with a similar background who's grown in this role — questions like these also signal that you're seriously thinking about your long-term development, which works in your favor either way.
