The Official Story ("Make People Rest") vs. the Real Story ("Keep the Company Running")
On paper, paid leave is a worker's right under Japanese law.
But on the ground, it's a system that's pretty hard to feel good about.
"Paid leave is your right." "But it disappears after 2 years." "And the company generally can't buy it back." "Companies must make you take at least 5 days a year." "But beyond that, at some workplaces, it's hard to take any."
Line it up like that and the obvious thought is:
Is this really a right that exists for workers?
In this article, we'll go through why paid leave expires after 2 years, why the minimum required is 5 days, and the gap between the official rationale and what actually happens at work.
1. The short answer: the official reason for 2 years is "to make people rest"
The direct reason paid leave vanishes after 2 years is the statute of limitations in Article 115 of Japan's Labor Standards Act.
According to the Ministry of Health, Labour and Welfare (MHLW), the right to claim annual paid leave expires after 2 years. In practice, leave you're granted can usually be carried over into the next fiscal year, but after that the time limit runs out and it's gone.
But here's the important part: "2 years" wasn't picked because it's the ideal length of time for rest, medically speaking.
The reasoning on the system's side goes like this:
Paid leave isn't a right for stockpiling. It's a right to take time off in that year.
So instead of letting people pile it up forever, the idea is to have them use it in the year it's granted, or at the latest the year after. That's the official logic.
When the statute of limitations in the Labor Standards Act was revisited in 2020 to match the revised Civil Code, annual paid leave was left at 2 years. The MHLW has said that leave is best taken within the year it's granted, and that, from the standpoint of raising usage rates, there's no need to extend it the way the right to claim unpaid wages was extended.
In other words, the official explanation is:
You're supposed to take paid leave every year, so a longer time limit would go against the purpose of the system.
In pretty words: "to make people rest."
But from the shop-floor point of view, it looks a lot more like this:
If your workplace lets you rest, then rest. If it doesn't, your leave gets incinerated after 2 years.
2. So why "2 years" exactly?
This is the part that bugs people the most.
Why not 3 years, 5 years, or 10?
When you dig into it, the 2-year limit on paid leave is a very old mechanism that goes back to just after the war. The Labor Standards Act was enacted in 1947, and a government notice from December of that year already treated the right to claim paid leave as being limited to 2 years under Article 115.
Materials from the Labor Policy Council explain that the old Article 115 set a 2-year limit on claims such as wages and compensation for workplace accidents, from the viewpoint of protecting workers and keeping business transactions stable.
So the number 2 is basically a design built around legal practice and labor administration:
- Settle claims in the employment relationship early
- Balance worker protection with legal certainty for employers
- Don't leave old rights and obligations between employers and workers hanging around forever
- If you can't use leave in the current year, you can still carry it into the next
Put the other way around, nobody chose "2 years" for the sake of workers' mental recovery or long breaks.
Two years isn't the best length of time for workers to rest. It's closer to the length of time it takes to tidy up an employment relationship.
That's what's infuriating.
Paid leave is explained as "a chance to refresh your mind and body." But dig into why it expires in 2 years, and what you smell is less about rest itself and more about sorting out legal claims, making things manageable for companies, and stabilizing labor-management relations early.
3. In 2020 there was a chance to change it. Paid leave was left alone
What's even more annoying is that in 2020 there was a real chance to revisit the time limits.
Alongside the Civil Code revision, the statute of limitations for wage claims was extended: 5 years in the text of the law, and 3 years for the time being.
But annual paid leave stayed at 2 years.
The MHLW's explanation is that paid leave is something that "should ideally be taken within the year it's granted," and that a longer limit would not fit the purpose of the system and could run against the policy goal of raising usage rates.
So the official logic is:
If we extend it to 5 years, workers might hoard their leave. Then it stops being a system where you rest every year. So we keep it at 2 years.
At first glance, that makes sense.
But in real workplaces, here's how it plays out:
You can't take time off, so it piles up. When it piles up, it expires. And because it expires, the cost of the company being understaffed gets pushed back onto the workers.
That's the garbage part of the structure.
If the point is "make people take time off every year," then the law should be putting much stronger obligations on companies: staffing that makes time off possible, backup coverage, and workloads designed with leave in mind.
In reality, even at workplaces where nobody can rest, leave still expires after 2 years.
At that point, paid leave stops being a "right to rest" and, depending on the workplace, turns into points with an expiry date.
4. Why is the minimum required leave "5 days"?
Next, let's look at the "5 days of paid leave a year" requirement that started in 2019.
Since April 2019, for workers who are granted 10 or more days of paid leave a year, the company has been required to make sure they take 5 days a year, even if that means the company has to pick the dates itself.
The Ministry of Health, Labour and Welfare explains the background like this: paid leave is meant to let workers refresh their minds and bodies, taken at times the workers request, but in reality usage rates were low because people felt awkward toward coworkers or hesitated to ask, so boosting usage had become a policy issue.
In other words, even the government knows:
Just giving people a right on paper doesn't mean they'll actually take paid leave.
So it imposed an obligation on companies to make sure at least 5 days get taken.
Why 5, though?
In the official materials, I couldn't find a clear one-line explanation of "why the number 5." But looking at how the system is built, a fair amount becomes visible.
Reason 1: The first grant of paid leave is 10 days
Under the Labor Standards Act, once you've worked continuously for 6 months from being hired and have attended at least 80% of all working days, you are generally granted 10 days of annual paid leave.
The people covered by the 5-day requirement are workers granted 10 or more days of paid leave a year.
So 5 days is exactly half of the minimum grant of 10 days.
That makes it easy to apply uniformly to everyone covered.
Reason 2: It's a bare-minimum enforced line, not "take all your days"
If the law had required "make everyone take all 10 days," the burden on companies for staffing, shift scheduling, and covering absences would suddenly get a lot heavier.
At restaurants, care facilities, hospitals, factories, shops, and small teams, the setup often isn't designed on the assumption that everyone can freely take 10 or more days.
So the system started by making the bare minimum of 5 days the company's obligation.
That looks less like worker protection and more like a minimum adjustment that won't break the company.
Reason 3: 5 days is close to "one week"
For someone working 5 days a week, 5 days is roughly one week of working days.
Of course, in practice you don't have to take them all in a row. But as the system looks from the outside, 5 days tends to become the line of "at least about one week off."
Still, that's hard to call enough rest.
Five days is less "enough days for a worker to recover mentally" and more "the lowest line that's easy to impose on companies."
5. Official story: "make people rest." Real story: "keep the company running"
Looking at all this, paid leave has quite a gap between the official face and the real motive.
| The official line | What looks like the real motive |
|---|---|
| Paid leave is a worker's right | But take it only as far as the company can keep running |
| It's so people can rest every year | If it could be saved up for a long time, the company's leave liability would blow up |
| It's to raise usage rates | But the minimum requirement is only 5 days |
| It's to refresh your mind and body | At workplaces where nobody can rest, unused leave still expires after 2 years |
| It's not a system for hoarding leave | Even when the reason you couldn't use it is the company's fault, it still gets burned |
That's what makes people angry.
Sure, if you could save up 5 years of paid leave, it would cause trouble for companies.
Everyone might take several months off before quitting. At shift-based workplaces, "there's nobody here today" could actually happen. The companies that didn't let people rest would end up carrying a huge leave debt later.
So I understand why companies like the 2-year limit.
But put the other way around, it also means:
Through 2-year expiry, the "bill for not letting people rest" that the company should be paying gets handed back to the workers.
6. Should "leave you couldn't take" really be erased?
If the system were truly designed to protect workers, there are other ways to do it, even if leave doesn't need to be stored forever.
One example is a "reserve leave" or "accumulated leave" system that saves up expiring paid leave.
MHLW materials also introduce company examples where expired annual leave is accumulated at up to 4 days a year, to a maximum of 40 days, and can be used for illness, nursing care, caring for family members, childcare, volunteer work, and so on.
So the system can be built.
The problem is that this isn't a nationwide legal obligation, but something closer to an optional company program.
If the goal were really to protect the right to rest, a design like this would be easier to accept:
- Make sure regular paid leave is taken properly every year
- Leave that couldn't be taken because of company circumstances, understaffing, or busy periods gets moved into reserve leave
- Reserve leave can be used for illness, mental health problems, caregiving, childcare, before retirement, and reskilling
- A cap is fine, but don't just burn it
- Departments with lots of unused leave get audited for understaffing and excessive workloads
That way you could land between "the company blows up" and "workers' rights get incinerated."
But current law doesn't go that far.
So on the ground, it ends up like this:
At companies where you can rest, it's a perk. At companies where you can't, it's a paid-leave incinerator.
7. Conclusion: Paid leave expiring after 2 years is a "bug that assumes you can take time off"
Here's the summary of why paid leave expires after 2 years:
- Under Article 115 of the Labor Standards Act, the right to claim annual paid leave expires after 2 years
- Behind that is an old system design aimed at settling employment-related rights early
- In 2020, the time limit for wage claims was revisited, but paid leave stayed at 2 years on the grounds that it's "something you should take every year"
- The 5-day requirement was introduced in 2019 as a response to the reality of low usage rates
- Five days is half of the minimum 10-day grant, and can be seen as the lowest line that's easy to make mandatory for companies
- But at workplaces where nobody can rest, 2-year expiry becomes an incinerator for rights, driven by company circumstances
The official purpose of the system is to let workers rest.
But from the shop-floor point of view, it looks like this:
Rest in name. Keep things running in truth. Burned leave.
If it were really for the workers, it would have to include not only "erase it after 2 years" but also "how do we change workplaces where people can't take it."
At an understaffed company, you can't take paid leave.
The leave you couldn't take expires after 2 years.
The company squares things up with just the minimum 5 days.
The rest gets burned.
That looks less like a worker's right to rest and more like a system that lets people rest the bare minimum so the company can keep running.
That's why these labels fit:
A paid-leave incinerator.
A right to rest, on paper.
A "you can obviously take time off" bug.
Paid leave is your right.
But at a workplace where you can't rest, it burns up after 2 years.
At that point, it's less a right than points with an expiry date.
