Low wages, long working hours, and an increasing burden due to the excessive demands of parents cause a shortage of childcare workers. There is also the NIMBY problem, where residents’ opposition to the construction of childcare facilities has forced them into poor conditions, such as under elevated railway tracks. All of these problems are caused by the fact that childcare is regarded as someone else’s business. A binary pits child welfare against economic activity and living conditions and excludes it. We tear away the asphalt that is paved by egoism. The soil opens up childcare, which used to be on the “other side” of the wall, to the city through activities such as composting, fieldwork and, children’s play in the soil.
