At RIKEN, we strive to ensure that both male and female personnel can achieve an ideal work-life balance so that they can make the most of their talents. Here is an introduction to the systems we have in place. However, please be aware that some support systems are available selectively depending on employment type, for example.

Individual consultations

Individual support coordinators

Individual support coordinators can provide individual consultations in response to various circumstances. Consultations are available on an as needed basis, and they will propose appropriate support to ensure that the employee can continue to work smoothly. Depending on circumstances, they raise issues with related departments and the Gender Equality Promotion Committee to get outcomes reflected into overall measures.

Systems related to work style

During pregnancy, employees commuting by train or bus can work up to one less hour either at the beginning or the end of their prescribed working time.

Commuting relief, etc.

During pregnancy and up to the child’s first birthday, female employees who have been examined by a doctor or midwife under the Maternal and Child Health Act and received guidance can make use of special measures such as mitigation of commuting, extra breaks, restrictions on duties, shortened working hours, or a leave of absence.
