Yes, regular passenger train services in Japan do not operate continuously through the night; most commuter lines, subways, and high-speed Shinkansen bullet trains stop running around midnight and resume operations early in the morning around 5:00 AM. This nightly shutdown window is essential for conducting strict track maintenance, safety inspections, and infrastructural upgrades necessary to maintain the world-famous punctuality and safety record of the Japanese railway system. Consequently, travelers stranded late at night must rely on taxis, late-night buses, or capsule hotels until morning service resumes.
