Tokyo's trains are legendary for their extreme congestion, particularly during the morning rush hour (7:30 AM to 9:30 AM) and evening rush (5:00 PM to 7:30 PM). In 2026, despite increased remote work options, major lines like the Yamanote, Chuo, and Saikyo lines still regularly exceed 150–180% of their designed passenger capacity during peak times. In these conditions, commuters are packed shoulder-to-shoulder, and "oshiya" (train pushers) may still be seen at major hubs like Shinjuku and Ikebukuro to ensure doors can close safely. Outside of these peak windows, however, the trains are remarkably efficient, clean, and often quite spacious. For tourists, the best strategy to avoid the "crush" is to travel mid-day (10:00 AM to 4:00 PM) or late at night. Even when crowded, the experience is notably orderly and quiet, as social etiquette in Japan strongly discourages talking on phones or making loud noise while on public transit.
