Among 1,225 male employees in four Japanese organizations, we randomized a two-hour work-life balance training and an information treatment correcting misperceptions of colleagues' support. Training increased fathers' weekend childcare by about one hour per day in young-child households and raised spouses' reported paid work; spouses' housework also fell. Training strengthened beliefs that paternity leave benefits workplace functioning but not leave intentions. Information modestly shifted perceived support but affected neither intentions nor information-seeking. Employer training can affect household allocation without changing formal rights or work arrangements. %K workplace intervention %K paternity leave %K household time allocation %K second-order beliefs %K field experiment
