Japan's Section Chiefs Average 49.5, Promoted at 38.6

A 45-year-old section chief in Japan is younger than most people in that seat. Most head offices outside Japan would read the same résumé as a career that stalled. The labor ministry's 2025 wage survey says the average person holding a section chief (kacho) post is 49.5, and the average department head (bucho) is 53.1. If you grade Japanese candidates by age, you will get most of them wrong.

What the two numbers count

They are the average ages of people who held a kacho-level or bucho-level post in June 2025. That is the age of the people in the seat. It says nothing directly about the age at which they were promoted, and the two get mixed up all the time.

The source is the Ministry of Health, Labour and Welfare's Basic Survey on Wage Structure (賃金構造基本統計調査) for 2025, published on 24 March 2026. The ministry sampled 79,321 establishments and got valid answers from 59,836, a 75.4% response rate. The published summary covers 52,242 private establishments with ten or more regular employees. The table by position counts only full-time workers on open-ended contracts. Part-timers and fixed-term staff are out. So are workplaces with nine or fewer people.

Each company decides who is "kacho level" based on its own titles. The kacho of a 15-person firm and the kacho of a 5,000-person firm sit in the same row.

How old are Japan's sitting managers?

Department heads average 53.1, section chiefs 49.5, subsection chiefs (kakaricho) 45.4, and people with no title 41.8. Their average tenure at the current employer is 22.6, 20.9, 17.5 and 10.8 years.

A second government survey lands in the same place. The National Personnel Authority's 2025 survey of private-sector pay, tabulated for companies with 100 or more employees, puts administrative section chiefs at 49.0 and department heads at 52.7. On the engineering side it is 49.5 and 53.3. Different agency, different sample, less than a year apart.

Look at the tenure column again. The average kacho is 49.5 and has been at the company for 20.9 years, which means joining before 29. Most Japanese section chiefs came up inside one company. Few were hired into the job.

The trend is the opposite of what you might expect. In 2020 this table was published for men and women separately, so compare men. Section chiefs went from 48.5 in 2020 to 49.5 in 2025. Department heads went from 52.9 to 53.1, subsection chiefs from 44.8 to 45.3. The ministry does not say in writing whether the two years tabulate positions on exactly the same basis, so treat this as a rough comparison. People have been saying for years that seniority is fading in Japan. It hasn't shown up in the age of the people in the seats. All three levels got older.

So when do they get promoted?

At 38.6 for kacho and 44.0 for bucho, according to the one international comparison I trust on definitions. Recruit Works Institute ran a five-country manager survey in 2014. It asked section chiefs and department heads in administrative and sales functions at companies with 100 or more employees. The analysis covered 1,553 managers, 429 of them in Japan and 308 in China.

In the same survey, managers in China reached section chief at 28.3 and department head at 29.8. In India it was 29.2 and 29.8, in Thailand 30.9 and 32.0, in the United States 34.6 and 37.2. Japan is ten years behind China at the first step and fourteen years behind at the second. The gap between the two steps is 1.5 years in China and 5.4 in Japan.

Japan promotes to section chief ten years later than China, and to department head fourteen years later

Promoted late, in the seat for a long time. That is how the average sitting section chief gets to 49.5 (MHLW, 2025). Age and title won't convert into a grade.

Discount this survey a little. It is from 2014 and I couldn't find a newer one with the same definitions. It also only asked people who had already been promoted, so everyone still waiting is missing. The 38.6 has probably moved since. I can't tell you which way.

Promoted at 38.6, average age in the seat 49.5. The two numbers fit together. Once promoted, people stay in the post for many years, and that pulls the sitting average toward fifty. What happens at the other end is in A third of ex-managers in Japan stepped down unexpectedly.

Where a foreign grade table misreads Japanese candidates

Reading by age fails in both directions.

It fails low first. A head office where people run departments at 32 sees a 42-year-old kakaricho and thinks: over forty and still not a manager. The grade comes out one level down. But the average kakaricho in Japan is 45.4. This person is early in the queue they are actually in, and the scope they carried at their last company may be what your grade table describes one level up. Candidates who are offered a step below where they are now rarely explain why they declined.

It fails high too. A 35-year-old kacho looks like a star who was fast-tracked. Sometimes the company is just small. The ministry's survey counts every workplace with ten or more people. The National Personnel Authority defines a kacho as the head of a section with two or more subsections, or ten or more members. Section chiefs above and below that line carry the same word on their business cards.

What I do is cover up age and title, write down the scope the person actually carried, and only then hold it against the grade table. I made the longer argument that grades belong to people and titles belong to seats in Grades Are Not Titles. Whether a person fits a role is something I check layer by layer with the five-level fit check, and age is in none of the layers.

The mismatch runs the other way as well. Send a country lead in their early thirties to Japan and the most experienced people on the team will be around fifty on average. So will the section chiefs across the table at customers. The presidents above them average over sixty. None of this means a young lead can't do the job. On the other side's scale, though, that age sits somewhere before kakaricho. A title won't close that gap. Written authority can. How large a contract can this person sign? Whose pay can they set? Will head office go around them?
