Especially when visiting large cities such as Tokyo and Osaka, you will want to avoid traveling during rush hour. Throughout Japan, rush hour typically lasts from 7 AM to 9 AM each morning, and 5 PM to 7 PM each evening. These are the times when many residents and going and coming from secular employment.

In 2026, you should strictly avoid long-distance train travel in Japan during the three "Great Holidays": Golden Week (late April to early May), Obon (mid-August), and the New Year period (late December to early January). During these times, the Shinkansen (bullet trains) are booked to capacity months in advance, and "unreserved" cars become extremely cramped with standing passengers. On a daily basis, you should avoid "Rush Hour" in major cities like Tokyo or Osaka, typically between 7:30 AM – 9:00 AM and 5:00 PM – 7:00 PM. During these windows, local commuter lines like the Yamanote Line reach "crush load" capacity, which can be overwhelming for travelers with luggage. Additionally, it is wise in 2026 to avoid the last train of the night (around midnight) on weekends, as they are often packed with revelers. If you must travel during peak periods, the 2026 recommendation is to book a "Green Car" (first class) seat well in advance to ensure a comfortable and stress-free journey.
