Japan uses a sophisticated, multi-layered train system dominated by the Shinkansen (high-speed "bullet" trains) and an extensive network of conventional lines. The Shinkansen, which translates to "New Main Line," operates on dedicated standard-gauge tracks and reaches speeds up to 320 km/h (200 mph). It is world-renowned for its punctuality, safety, and frequency. Complementing the Shinkansen is a vast network of conventional lines (often narrow-gauge) operated by Japan Railways (JR) Group companies and dozens of private railway operators. In major cities like Tokyo and Osaka, these are supported by efficient subways and monorails. The system is highly integrated, allowing passengers to use a single "IC card" (like Suica or Pasmo) to tap in and out across different companies and modes of transport. In 2026, Japan continues to push boundaries with the development of the Chuo Shinkansen Maglev, which aims to connect Tokyo and Nagoya at speeds exceeding 500 km/h.
