If you run an English school in Japan, you probably know the pattern.
A child joins at four, five, or six years old. They enjoy class. The parents seem happy. Then, around upper elementary school or junior high, the family says they are too busy. Juku has started. Club activities are more serious. Entrance exams are coming. English is the activity that gets cut.
It is easy to say, “That is just how it is in Japan.”
The 2026 student retention research from AAS Press suggests there is more to it. JOBS IN JAPAN helped support the survey by assisting with data collection, and the findings are useful for any English school owner trying to understand why students leave before they get the full benefit of years of study.
The full report, Don’t Leave: Understanding Student Retention in English Language Schools in Japan, is worth reading in detail. This article gives you the short version.
Students usually leave at predictable times
The AAS Press research gathered survey responses from 147 English language school owners and managers in Japan. The data is self-reported, so it should not be treated as a perfect national measurement. Still, the pattern is clear enough to matter.
Many students begin English study between ages four and six. The most common reported leaving ages cluster around 10 to 12 and 13 to 15. This article calls these two windows the danger years: the stretch of late elementary school and early junior high when families quietly decide English is no longer worth keeping.
That means many students are not leaving randomly. They are leaving during late elementary school and early junior high, exactly when juku, entrance exam preparation, club activities, and heavier school demands start squeezing the family schedule.
For owners, this is not only a classroom issue. It is a business issue. If students leave at the same stage every year, the school has to keep replacing them with new students. Marketing pressure rises, classes become less stable, and revenue gets harder to predict.
The main reason is not always lesson quality
The most common reason reported for students leaving was going to cram school. Other common reasons included scheduling conflicts, entrance exam study, moving away, being too busy, and low motivation.
That does not mean lesson quality is unimportant. Poor lessons will always hurt retention. But the research suggests that many students leave because English loses its place in the family’s priorities.
When a child is in kindergarten, parents may be happy if the child enjoys class and has a positive first experience with English. By upper elementary school, parents start asking, “What is this leading to?”
By junior high, the question becomes more direct: “Will this help my child at school, with exams, or in the future?”
If the school is still explaining the value of English in the same way it did when the child was five, parents may start looking elsewhere.
High-retention schools prepare before the drop-off happens
One of the strongest lessons from the case studies is that high-retention schools do not wait until families are already thinking about quitting.
Brian Shepherd’s i2i in Yamanashi responded to a Grade 3 and Grade 4 drop-off by creating the Explorers program for upper elementary students. Students still studied English, but they also joined experiential sessions and monthly activities such as camps, outdoor projects, cooking, science, journals, and reflection work.
The point was not just to make class more fun. It made English part of the student’s identity. Students became “Explorers.” They belonged to a group. They had memories, status, and a reason of their own to continue.
Claire Sezaki’s Sunshine English School in Kumamoto takes a different approach. Her school only accepts new students in Grade 1 and keeps them moving through a stable cohort. That model will not fit every school, but the principle is worth noting: retention starts before enrollment. Families understand the path from the beginning, and the school protects class level, expectations, and peer stability.
Ben Shearon’s Cambridge English School in Sendai rebuilt its teen program so junior high students had reading, speaking output, and school-English support in one clear structure. David Chandler’s ABCDAVID’S tracks junior high test results, offers grammar support, and intervenes when students need help.
Different schools, different systems. The shared point is that they make the next stage visible before families drift away.

Parents need proof that staying is worth it
Enjoyment helps, but it is rarely enough through junior high.
Parents need to see progress in a form they understand. That might be observation lessons, reading homework, Eiken milestones, school test scores, interviews, progress checks, or clear examples of what students can now do.
The exact method depends on the school. A conversation-focused school and an academic English school may show progress differently. What matters is that parents do not have to guess.
This becomes more important as students get older. A child who loved English songs at six may not show the same excitement at 12. That does not always mean they should quit. It may mean the school needs to show the student and the parents a new reason to stay.
JOBS IN JAPAN has a related employer article on the biggest problems in workspaces in Japan, which looks at teacher wellbeing and workplace pressure. For school owners, staff stability and student retention are connected. Families notice when a school is organized, consistent, and able to support students over several years.
Re-recruit families at each transition
A family does not decide once to stay for nine years. They decide again and again.
They decide when the child enters elementary school. They decide when homework gets harder. They decide when juku starts. They decide when lesson length, tuition, or expectations increase.
Good retention work means treating these moments as re-recruitment points.
- Before Grade 4: explain how the upper elementary program changes and why.
- Before Grade 6: show the junior high pathway in detail.
- Before a fee or lesson-time increase: explain what the family is getting in return.
- Before parents start comparing you with juku: explain how your school supports school English, Eiken, communication, or the specific outcome your program promises.
Do not wait until a parent says, “We are thinking of stopping.” By then, they may have already made the decision emotionally.
What school owners should do next
If you own or manage an English school in Japan, start by finding your own danger years.
Look at withdrawals from the past two or three years. Track age, grade, years enrolled, class type, reason for leaving, and month of withdrawal. If you do not have this data yet, start collecting it now.
Then ask:
- Where do students first start to leave?
- What changes in the family’s life at that point?
- Have we explained the next stage early enough?
- Are we showing progress in a way parents understand?
- Do older students feel they belong here?
- Are we giving families a clear reason to choose us over juku, clubs, or doing nothing?
The best retention strategy is not last-minute persuasion. It is building a school where staying feels like the natural next step.
