In 2026, the Nozomi is the fastest service on the Tokaido Shinkansen line, but the "speed" is measured in travel time, not just top velocity. All three main train types—Nozomi, Hikari, and Kodama—reach the same top speed of roughly 285 km/h (177 mph) on the Tokyo-Osaka stretch. However, the Nozomi is "faster" because it skips almost all intermediate stations, stopping only at major hubs like Nagoya and Kyoto. A trip from Tokyo to Shin-Osaka on a Nozomi takes about 2 hours and 22 minutes, whereas the "all-stop" Kodama takes nearly 4 hours. That makes the Nozomi roughly 60% faster in terms of total duration. A supportive 2026 peer tip: if you are using the JR Pass, remember that the Nozomi requires a "supplemental ticket" fee, whereas the slightly slower Hikari (which takes about 2 hours and 53 minutes) is usually included in the base pass.
