Japanese culture values family harmony and cooperation, which extends to child-rearing practices such as where babies sleep. The traditional Japanese sleeping arrangement for infants involves co-sleeping with parents or grandparents in a small crib-like bed called a "shokibed" or "akachan bed". While co-sleeping has benefits such as promoting bonding and making nighttime feedings easier, it also comes with risks such as suffocation and an increased risk of sudden infant death syndrome (SIDS). To address these risks, Japanese parents take precautions such as using firm mattresses and avoiding soft bedding. Safe sleeping practices are crucial regardless of where babies sleep. Cultural differences in baby sleeping arrangements exist across the world, and foreign parents living in Japan may find traditional co-sleeping arrangements challenging due to cultural differences and language barriers. Co-sleeping remains a controversial topic among experts and parents alike.
