The Nozomi is the fastest and most frequent service on the Tōkaidō and San'yō Shinkansen lines in Japan, reaching a top operating speed of 300 km/h (approximately 186 mph). On the Tōkaidō segment between Tokyo and Osaka, the speed is slightly capped at 285 km/h due to the age and curvature of the tracks, but on the San'yō segment toward Fukuoka, it hits the full 300 km/h mark. Using the latest N700S series trainsets, the Nozomi can travel from Tokyo to Kyoto in just about 2 hours and 15 minutes, and to Osaka in roughly 2 hours and 30 minutes. It achieves these high speeds while maintaining an incredible record for punctuality and safety, with average delays often measured in mere seconds. Unlike the Hikari or Kodama trains, the Nozomi stops only at the largest major stations, making it the preferred choice for business travelers and tourists looking for the quickest transit. It is important to note that the Nozomi is generally not covered by the standard Japan Rail Pass, requiring a supplementary "Nozomi-Mizuho" ticket for pass holders.
