Japanese Prime Minister Sanae Takaichi has sparked a national debate over work-life balance after revealing she typically survives on zero to three hours of sleep per night. The admission, shared via social media during a July public holiday weekend, has led critics to question the sustainability of her leadership schedule.
The controversy began when the Prime Minister used her X account to describe her activities during a three-day weekend ending July 20, which included Marine Day on the last day. While many Japanese took advantage of the summer holiday by heading to beaches and seaside destinations, Takaichi reported spending her time catching up on policy documents and handling household chores.
In a post that attracted more than 31 million views, Takaichi noted that she had finally managed to get a full five hours of sleep for the first time in ages
. She clarified that since taking office, a regimen of zero to three hours of sleep has become the norm
.
The Domestic Burden: Chores and Dawn Work
Takaichi’s sleep deprivation is not solely the result of official duties, but a collision between high-level governance and domestic labor. She detailed a grueling weekday routine where her return to the official residence is immediately met with household responsibilities.
According to reporting by ABC News, Takaichi explained that the hours following these chores are consumed until dawn with reading materials brought back from the Prime Minister’s Office or prepping for question time. Even during her brief holiday respite, she spent time ironing undergarments, sewing worn-out skirts and reinforcing loose buttons on her jackets.
This approach is consistent with a pattern established upon her ascent to leadership. Takaichi previously announced she would scrap her work-life balance in favor of a relentless work ethic, and she has faced past criticism for summoning aides for meetings at 3am.
Political Backlash and National Security Concerns
The Prime Minister’s admission has shifted the public conversation from her work ethic to her cognitive fitness. Opponents have warned that extreme sleep deprivation could impair judgment and affect national crisis management, with some critics framing the situation as a national security risk.
Yuichiro Tamaki, leader of the Democratic Party for the People, explicitly criticized the lack of support from the Prime Minister’s staff during a press conference on July 21.
“Resting is part of her job. I wonder, would it be better to focus her valuable time on decisions and tasks that only the prime minister can handle?”

Tamaki further questioned why Takaichi’s entourage does not provide more support to ensure she can make important decisions with a fresh mind
. Conversely, some colleagues have defended the Prime Minister. Deputy foreign affairs minister Ayano Kunimitsu wrote on X that each person has their own circumstances and asked for understanding provided that public duties are fulfilled.
The Cognitive Cost of ‘Karoshi’ Culture
The debate over Takaichi’s schedule mirrors a broader systemic issue in Japan. The country’s corporate culture of extreme hours has led to the term karoshi
, or death by overwork, which describes deaths resulting from strokes, heart attacks, or by taking their own lives. While reforms were introduced in 2022 following a doctor’s suicide, the Prime Minister’s own habits suggest these pressures persist at the highest levels of government.

The physiological implications of Takaichi’s schedule are significant. Bruno van Swinderen, a researcher at the Queensland Brain Institute and professor at the University of Queensland, stated that someone maintaining such hours would be extremely sleep deprived
.
According to van Swinderen, a brain with massive sleep debt prioritizes deep, slow-wave sleep for repair, often at the expense of rapid eye movement (REM) sleep. This deficiency is particularly critical for a national leader because REM sleep governs emotional regulation and cognitive flexibility.
While Takaichi is not the first world leader to maintain a sparse sleep schedule—with figures like Margaret Thatcher, Emmanuel Macron, and Angela Merkel cited as having similar habits—the transparency of her current routine has turned a personal habit into a public debate over the sustainability of Japan’s leadership culture.
