Japan’s Labor Standards Act has protected menstrual leave since 1947. If a woman says her period makes it hard to work, the company legally can’t refuse. There’s no limit on days, and you can even request it by the hour.
In theory, it’s one of the progressive workplace protections out there. In practice? A lot of women still feel weird about taking it — and some get called out when they do.
The viral post that hit a nerve
On August 1, an office worker posted that HR pulled her in for a talk. She was the only person in the company using menstrual leave every month.
They basically told her, “You’re the only one who takes it every single month.”
She fired back that her periods come with violent diarrhea so bad she ends up lying on a futon next to the toilet. If they wanted her at the office, that’s what they’d be dealing with. HR went quiet.
The post blew up — tens of thousands of likes and millions of views — under the hashtag “We want to talk about our periods.” A lot of women related hard. Some shared their own stories of being questioned or made to feel like they were abusing the system. Others pointed out the obvious: if the leave exists, why shame people for using it?
Why so few people take it
The numbers are pretty stark. One ministry survey found only 0.9% of eligible women used menstrual leave in fiscal 2020. That’s a massive drop from 26% in the early 1960s.
A few reasons for that:
- In about two-thirds of companies, the leave is unpaid. So a lot of women just use regular paid vacation days instead — no income hit and no need to explain why.
- Asking for it often means telling a male boss or HR about your period. Many people simply don’t want to.
- Workplaces are frequently understaffed, so taking extra time off feels like burdening colleagues.
- Better painkillers, pads, and birth control have made symptoms more manageable for a lot of women compared to decades ago.
But “more manageable” isn’t the same as “no big deal.” Severe cramps, heavy bleeding, endometriosis, PCOS, and period-related digestive issues are still very real for plenty of people. Working through those days isn’t always an option.
Some companies are trying to fix the stigma
A few places are experimenting. One IT company started offering one paid day of menstrual leave per month and ran company-wide education sessions. Another Osaka firm rebranded it as “Life Support Leave” — a gender-neutral category that also covers fertility treatment and other life stuff. Usage there is much higher.
The idea is simple: if you make it less awkward and less of a financial hit, more people will actually use what they’re entitled to.
Japan has had this right on the books for nearly eight decades. The fact that taking it can still feel like a risk says a lot about how far workplace culture still has to go.
