Kurumin certification くるみん

The government certification for employers that support staff raising children. Also written Platinum Kurumin, Try Kurumin, Kurumin Plus.

Kurumin is awarded by the Minister of Health, Labour and Welfare, through the prefectural labour bureaus, to employers that complete an action plan under the Act on Advancement of Measures to Support Raising Next-Generation Children and meet a set of criteria. The law has been extended to 31 March 2035. There are three tiers: Try Kurumin, Kurumin and Platinum Kurumin. A separate Plus mark can be added at any tier for support with fertility treatment.

The criteria were raised for applications from 1 April 2025, and the thresholds that matter most are for men taking childcare leave:

All tiers also require at least 75% of women, now including fixed-term women, to take childcare leave. Kurumin and Platinum add a working hours test: average monthly overtime and holiday work below 30 hours for all full-time staff, or below 45 hours for full-time staff aged 25 to 39. Applications under the old standards are accepted until 31 March 2027. Platinum Kurumin holders publish their results annually instead of filing new plans.

For context, the government's Basic Survey on Equal Employment found that 50.9% of eligible men took childcare leave in fiscal 2025.
