The Perinatal Mental Health Consensus Guide 2017 in Japan consists of recommendations and explanatory text on 20 clinical questions. The guide not only describes guidelines and methods of support, but also the support structure, such as organizational structure and collaboration, that is a prerequisite for support provision. For example, Clinical Question: CQ5 refers to the role of the receiving psychiatric hospital and its response to outpatient treatment and hospitalization. CQ6 also states that when child abuse is suspected, collaboration should be handled not by individuals but by organizations such as the hospital's child protection team.
 In utilizing the principles and guidelines of the guide, Gakujikai Kimura Hospital serves as a recipient of postpartum mental health care collaboration for mild to severe cases. For mild cases, the hospital provides expert advice to municipal public health staffs, and for moderate cases, it opened a women's outpatient clinic and a stress care ward in July 2017, creating a system that can promptly provide medical care. In addition, the hospital takes on severe cases through psychiatric emergency admissions, albeit with the limitation that there are no obstetric complications. Since the opening of the specialized outpatient clinic, a total of 338 eligible patients have been treated through the end of June 2022, five years after the clinic was opened. In order to smoothly provide psychiatric treatment for postpartum women, the following are required: (1) a full-time medical team consisting of physicians, psychologists, and others, including social workers who are familiar with local resources and networks for maternal and child health, (2) hiring staff who can provide childcare and childcare, (3) improving the facility environment (dedicated waiting rooms, consulting rooms, nursing rooms, etc. ), and (4) "Family Support Team: FAST" to work in close cooperation with the Child Guidance Center, and (5) establishment of opportunities for regular training, study, and information sharing with the maternal and child health care side.
