Summary
Cram school stocks are hard to judge if the only question is, "Which companies can still win despite Japan's declining birthrate?"
The real checkpoints are less flashy: student volume, pricing, and operating cash flow/FCF. Waseda Academy and Nagase remain names to keep checking, but with conditions. Riso Kyoiku needs proof that its high-unit-price portfolio can translate into better profitability. Johnan Shinken Holdings still needs a clearer margin recovery and turnaround scenario.
The education sector should not be sold mechanically just because the population is shrinking. But it is also not an area where investors can casually buy anything with an "exam demand" story attached to it.
The Risk of Looking for Simple Winners
When looking at cram school stocks, it is tempting to frame the discussion around "which companies can grow even as the number of children declines."
That instinct is understandable. When the demographic headwind is this large, investors naturally want to separate the survivors from the companies likely to fall behind.
But that framing is a little too rough.
The cram school industry cannot be explained by school-age population alone. At the same time, it is not as simple as saying, "Demand for difficult-school entrance exams is strong, so the business is fine."
What matters is much more mundane.
Are student numbers holding up? Is pricing improving? Is cash actually left over?
Without checking those three points, it is risky to line up Waseda Academy, Riso Kyoiku, Nagase, and Johnan Shinken Holdings and label them "promising" or "cautious." Anyone actually reading the earnings releases is unlikely to view them that mechanically.
At this stage, my provisional view is that Waseda Academy and Nagase deserve continued monitoring, but with conditions. Riso Kyoiku is a wait-for-profitability story. Johnan Shinken Holdings still needs clearer evidence of a credible re-growth scenario.
The First Numbers to Check
Looking at the full-year results for FY2026/3 or FY2026/2, the differences between the companies are already fairly clear.
| Company | Revenue | Operating Profit | Operating Margin | Net Profit | Equity Ratio | Operating CF |
|---|---|---|---|---|---|---|
| Waseda Academy | JPY 37.658bn | JPY 3.960bn | 10.5% | JPY 2.487bn | 63.2% | JPY 0.420bn |
| Riso Kyoiku | JPY 34.240bn | JPY 2.704bn | 7.9% | JPY 1.615bn | 53.8% | JPY 2.000bn |
| Nagase | JPY 64.183bn | JPY 5.979bn | approx. 9.3% | JPY 3.983bn | 37.7% | JPY 10.546bn |
| Johnan Shinken Holdings | JPY 5.621bn | JPY 0.077bn | 1.4% | JPY 0.004bn | 27.2% | JPY 0.123bn |
The two figures that stand out at first glance are Waseda Academy's 10.5% operating margin and Nagase's JPY 10.546bn in operating cash flow.
Still, an operating margin alone does not make a stock buyable. Cram school businesses can show a gap between earnings and cash because of advance payments, seasonality, school expansion, labor costs, and advertising expenses.
The sequence investors should use comes before operating profit. First, are student numbers holding up? Next, is pricing improving? Finally, is operating cash flow converting into FCF?
If you skip that sequence, the analysis can stop at "the margin is high" or "cash flow is strong." With education stocks, that is a fairly dangerous shortcut.
Why "Declining Birthrate" Is Too Simple
The difficult thing about cram school stocks is that the overall industry faces demographic pressure, while parts of the exam market remain relatively resistant to price erosion.
In areas such as junior high entrance exams in the Tokyo metropolitan area, difficult high school entrance exams, medical school preparation, and top university exam prep, household spending priority tends to remain high. These markets cannot be explained by population decline alone.
Regional and general remedial markets are different. When the student base shrinks, utilization can fall quickly. Classrooms still have fixed costs. Instructors are still needed. Advertising is not easy to stop. If student volume falls on top of that, profits can decline faster than sales.
That is the uncomfortable part of cram school stocks.
So the unit of analysis should not be "the cram school industry" as a whole. It should be broken down more finely:
- junior high entrance exams
- high school entrance exams
- university entrance exams
- individualized tutoring
- high-unit-price areas such as medical school, kindergarten, and elementary school entrance exams
- regional remedial education
Without that segmentation, broad industry discussion and individual company strength get mixed together.
The Three KPIs
For cram school stocks, KPIs are not a neat checklist. They are tools for questioning where revenue growth is actually coming from.
The first number to check is student volume. Then pricing. Then operating cash flow and FCF. That order works.
But each item answers a different question. Student volume tells us whether demand is still there. Pricing tests whether price increases are really sticking. Operating CF and FCF show whether accounting profit is turning into cash that can ultimately matter to investors.
1. Student Volume
Student volume comes first.
If revenue is growing while student numbers are falling and the entire story depends on higher unit prices, there is eventually a limit. Growth investors will look here first. Price increases can support one or two years, but if the base of students narrows, classroom utilization will eventually feel it.
Of course, a fall in student numbers is not automatically bad if the company is deliberately exiting lower-margin student segments and shifting toward higher-unit-price groups.
Even then, the key is which students are increasing and which students are falling.
For cram schools, student mix by grade and exam category matters. Are more upper-tier difficult-school students joining? Or is the company simply losing lower-unit-price general students? Are students per classroom holding up?
The meaning of revenue growth changes materially depending on that mix.
2. Student Unit Price
Next is pricing. This matters a lot, but investors should not take it at face value.
Are price increases actually being accepted? Is the average unit price rising because students are taking more courses? Is it being lifted by seasonal courses? Or is the company using discounts to defend headline student numbers?
The future margin profile changes significantly depending on the answer.
For exam-focused cram schools, spring, summer, winter, and last-minute exam courses can have a large impact on unit price. Investors need to separate structural pricing improvement from one-off seasonal demand.
3. Operating CF and FCF
Finally, cash.
Even if accounting profit is positive, long-term investors will struggle to assign a higher valuation if school investment, hiring, systems investment, and advertising consume the cash.
This is where Nagase's operating cash flow stands out. Waseda Academy, by contrast, has a good margin, but the gap between profit and operating CF deserves continued monitoring.
Cram school businesses can also look strong on operating CF because of advance payments. That is why operating CF alone is not enough. FCF after investing cash flow also needs to be checked.
What to Look For in IR Materials
There is no need to overcomplicate the screen. Simply lining up the following items can change how the companies look.
| KPI | Numbers to Check | How to Read Them |
|---|---|---|
| Student volume | enrolled students, YoY growth/decline, students per school, withdrawal rate | tests whether revenue growth is really backed by demand |
| Student unit price | revenue per student, seasonal course sales ratio, price increase rate, discount rate | separates real pricing power from course mix or discounting |
| Cash | operating CF, FCF, operating CF margin, FCF margin | checks whether profit is ultimately left as cash |
Revenue per student can be approximated by dividing revenue by average enrolled students. Operating CF margin can be estimated by dividing operating CF by revenue.
It is not a perfect analysis, but it is enough to spot inconsistencies across companies.
Company-by-Company View
Waseda Academy
Among the four companies, Waseda Academy is the easiest to read.
For FY2026/3, revenue rose 7.4% year on year and operating profit rose 11.6%. The operating margin was 10.5%. The earnings release also disclosed an average student count of 50,837, up 4.0% year on year. The margin is not floating on its own; student volume is also increasing, which makes the result easier to evaluate.
From here, though, the main issue is less profitability and more market share.
Waseda Academy cannot be understood in isolation. In the junior high entrance exam market, SAPIX, Nichinoken, Yotsuya Otsuka, and others compete intensely for upper-tier students. Even if Waseda Academy is improving its difficult-school acceptance results, that is not the same thing as proving sustained student inflow.
For long-term investors, the order of questions is probably not acceptance results first. It is whether upper-tier student numbers are rising, whether students per school are holding up, and whether instructor hiring costs are starting to pressure margins.
The numbers are not bad. In fact, Waseda Academy is relatively clean at this point. But if the share price begins pricing in further expectations, the next question will be how many years this margin can last.
My provisional view is B, conditional. If market share gains can be confirmed in the numbers, there is room for a higher assessment.
Riso Kyoiku
Riso Kyoiku is a company where I would look at margins before revenue.
Its portfolio is attractive in principle. TOMAS, Medic TOMAS, Shingakai, and Meimonkai give it exposure to high-unit-price areas. Individualized tutoring, medical school prep, and kindergarten/elementary school entrance exams are markets where household willingness to spend tends to remain relatively resilient. The company is positioned in areas where spending may survive even under a declining birthrate.
The question is how much of that high unit price remains as profit.
In FY2026/2, revenue rose 2.5% year on year, while operating profit fell 7.8%. Reading the earnings release, the pressure appears to come from instructor hiring and labor costs, higher fixed costs, and a revenue shortfall versus plan. In other words, even a high-unit-price service can lose margin quickly if instructor costs and classroom utilization move the wrong way.
This feels less like a pure growth stock and more like a profitability recovery story. Operating CF of JPY 2.000bn is not bad, but I would want to know how much remains after investing CF. I would also want to separate profitability by brand: TOMAS economics, utilization in medical school prep, and price retention in kindergarten/elementary school exam prep.
This is not a case of "high unit price, therefore strong." It is a company where the key question is: if the unit price is high, why has the margin not yet recovered?
The provisional assessment is B-C, waiting for profitability conversion. The portfolio is interesting. But for institutional investors to get comfortable, another step in margin recovery and FCF confirmation is needed.
Nagase
Nagase should be viewed first through operating cash flow.
Operating CF of JPY 10.546bn is conspicuous among education stocks. Revenue rose 16.2% year on year and operating profit rose 22.9%. The operating margin was about 9.3%, close to Waseda Academy.
That said, net profit movements should not be taken too literally for Nagase. Equity-method effects and impairment-related rebound factors can distort the surface-level profit trend.
The more important issue is whether its cash generation, including the advance-payment structure, can continue.
Nagase operates Toshin High School and also has the Toshin Satellite School network. Its cash structure is not the same as a direct-operated classroom-heavy cram school.
Video-based instruction can have high marginal profitability once content investment has been recovered. On the other hand, if student growth stalls, fixed costs and systems investment can remain heavy.
So the strong operating CF is worth valuing, but it should not be the end of the analysis. Dividend investors may find the cash generation attractive, while growth investors will likely want to break down high school market share and Toshin's ability to maintain unit pricing.
The items to watch are room for expansion in franchise schools, the marginal profitability of the video-class model, high school market share under demographic pressure, Toshin's pricing power, and whether the sports business integration is actually improving margins.
Can the Toshin brand maintain student numbers and pricing in the high school segment? Is the sports business really contributing to operating margin improvement? Those are the points I would keep watching.
The provisional assessment is B, conditional. Cash is strong. But the quality of earnings needs another layer of analysis before the assessment can be raised.
Johnan Shinken Holdings
Johnan Shinken Holdings is not yet a growth story. It is a turnaround verification story.
For FY2026/3, revenue was JPY 5.621bn and operating profit was JPY 0.077bn. Moving from an operating loss to a profit is progress, but the operating margin was only 1.4%. At that level, a small deterioration in the environment can erase profit quickly.
Operating CF was positive, but a stronger view requires a clearer path to margin improvement. Student numbers, pricing, instructor unit costs, classroom profitability: without knowing where the improvement is coming from, it is hard to build a re-growth scenario.
To take a more constructive view, I would want to see signs that the operating margin can improve at least toward the 3-5% range. A small rebound in student numbers is not enough. The key question is whether each classroom can absorb fixed costs and improve profitability.
This is a company where the key question is less short-term profitability and more which businesses it will keep and where it will actually earn money. If the operating margin starts to recover, the view can change. But at this stage, there is not enough evidence to say the winning path is visible.
The provisional assessment is C, cautious. The company is still in the process of rebuilding credibility.
How to Think About SAPIX and Tokyo Individualized
This is another area where it is easy to misunderstand the setup.
The fact that Tokyo Individualized has left the listed market does not automatically make the remaining listed cram school stocks stronger. It does, however, reduce the number of listed individualized tutoring comparisons, which can make investors pay more attention to names such as Riso Kyoiku, Waseda Academy, and Nagase.
SAPIX, meanwhile, is unlisted but cannot be ignored when analyzing the exam market. It matters not for profit comparison, but because it absorbs a meaningful share of upper-tier demand.
Waseda Academy, SAPIX, and Nichinoken each occupy different positions in the exam market. If investors look only at listed companies and ignore that structure, they will miss the reality of the market.
It is not enough to read only the earnings releases of listed companies. Investors also need to think about which student segments the major unlisted schools are taking.
Demographic Pressure From 2027 Onward
The decline in school-age population from 2027 onward is a theme the cram school industry cannot ignore.
But it will not hit all regions in the same way.
In the Tokyo metropolitan area, demand for integrated junior/senior high school and difficult-school exam prep is likely to remain relatively resilient. Pricing may also hold up better. In regional areas, the decline in the student base may hit first. Price increases will be harder, and classroom maintenance costs will feel heavier.
Another point to watch is the polarization of education spending.
Even if the number of children declines, education spending will not necessarily fall evenly. Spending on difficult-school exam prep and medical school prep may remain resilient, while remedial education markets face stronger contraction pressure.
The more important question may not be population decline itself, but which households keep spending on education and which segments see spending cut.
Without looking at regional differences and income-level differences, analysis of cram school stocks becomes very rough.
Overall View
It is risky to analyze cram school stocks as a simple search for companies that can "win despite the declining birthrate." Even among these four companies, all in the same education sector, the key questions are quite different.
For Waseda Academy, I care more about sustained share in the junior high entrance exam market than the current margin. For Riso Kyoiku, I want to know why margins have not fully recovered despite its high-unit-price services. Nagase's operating CF is impressive, but the advance-payment structure and video-instruction model need to be broken down. For Johnan Shinken Holdings, classroom profitability matters more than the fact that it returned to operating profit.
Viewed this way, the biggest issue is not simply whether these companies can beat the declining birthrate.
It is whether they are capturing the segments where education spending remains. Whether unit prices are rising in a sustainable way. And whether profit is actually staying in the business as cash.
At this point, Waseda Academy and Nagase remain names to keep monitoring with conditions. Riso Kyoiku needs confirmation that its high-unit-price portfolio is converting into profitability. Johnan Shinken Holdings still needs its re-growth scenario to be tested again.
Personally, in the next round of results, I would focus less on headline revenue growth and more on the combination of student volume and classroom profitability. If that holds, these companies can withstand some of the broad declining-birthrate narrative. If it breaks, then phrases like "difficult-school demand" and "high-unit-price segment" will not be enough to support the investment case.
Cram school stocks are tempting to buy on story. In the end, though, the analysis comes back to rather unglamorous numbers.
