The growing income gap, known as the "Tama River Divide," between different regions in Tokyo has been causing distress among working mothers, dubbed "WarMamas." The lack of affordable childcare in wealthier areas forces many of them to travel far for affordable services. The issue is stirring debate over Japan's social and economic policies, and highlights the challenges working mothers face in managing their careers and raising children amidst escalating living costs.

In Japan, addressing the needs of working mothers and curbing income disparity are high on the sociopolitical agenda. The Tama River Divide refers to income disparity in Tokyo's different wards. The lack of affordable childcare in wealthier regions points to a broader problem of social resources being unevenly distributed, leading to stress and inconvenience for working parents, particularly mothers.

In the US or EU, childcare issues and income inequality are also top concerns. Government-sponsored programs and legislation aim to help working parents with childcare, though the level of success varies by country and region. Solutions like flexible work schedules or work-from-home options are becoming more common, but affordability and accessibility of childcare remain significant obstacles to achieving work-life balance.
