Japan clarifies rules for sleeping in vehicles at rest stops

Japan's Ministry of Land, Infrastructure, Transport and Tourism has clarified that sleeping in vehicles at roadside stations (Michi-no-Eki) and highway service areas (SA/PA) is not entirely prohibited but is restricted. Short naps for driver fatigue recovery are permitted as these facilities are designated rest areas. However, overnight stays for accommodation purposes are discouraged and considered non-compliant with intended use. Some stations offer dedicated overnight spaces, but travelers should check local rules and avoid activities that could disturb others.
