To travel from Tokyo to Osaka via the Shinkansen (Bullet Train), you must go to Tokyo Station or Shinagawa Station. Both stations serve the Tokaido Shinkansen line, which is the most frequent and popular route in Japan. Tokyo Station is the "starting point" and offers the best chance of finding unreserved seats, while Shinagawa is often more convenient for those staying in the southern part of the city. You will be traveling to Shin-Osaka Station, as the "regular" Osaka Station does not have Shinkansen platforms (they are connected by a short 4-minute local train ride). In 2026, the fastest train is the Nozomi, which completes the journey in approximately 2 hours and 30 minutes. You can buy tickets at the "Midori-no-madoguchi" (Green Window) counters or via the SmartEX app, which allows you to use your mobile Suica or IC card to tap through the Shinkansen gates for a truly seamless, paperless 2026 travel experience.
