Core Event: Prime Minister Discloses Minimal Sleep
Japanese Prime Minister Sanae Takaichi revealed on X that she typically sleeps “zero-to-three hours” each night since taking office in October 2025. She added that after returning to the prime minister’s residence she spends her limited private time on household chores before resuming “late-night hours… until dawn” reading policy documents and preparing for question time.
Background & Context: Overwork, “Karoshi,” and Reform Efforts
Japan’s corporate culture has long featured long workdays, a factor behind the term “karoshi” (death by overwork). Official statistics show hundreds of deaths each year linked to overwork-related health crises. In response, the government introduced a four-day workweek for Tokyo municipal employees last year, aiming to improve work-life balance amid rising burnout and a declining birthrate. Governor Yuriko Koike has promoted flexible schedules as a way for both women and men to align work with personal circumstances.

- A Randstad 2025 Workmonitor survey found 74 % of Gen Z workers rank work-life balance above pay when choosing an employer.
- Microsoft Japan’s 2019 four-day-week trial reported a 40 % increase in productivity.
