On the route from Shinagawa to Osaka, travelers can utilize the Shinkansen services, primarily the Nozomi and Hikari trains. The Nozomi Shinkansen is the fastest option available, operating at speeds of up to 300 km/h (186 mph) and completing the journey in approximately 2 hours and 30 minutes with fewer stops. Key stations along this route often include Shin Yokohama, Nagoya, and Kyoto. On the other hand, the Hikari Shinkansen, which serves the same route, makes additional stops and usually requires around 3 hours to reach Osaka. While both trains cater to passengers with Ordinary and Green class seating, the Nozomi is preferable for those prioritizing speed, while the Hikari provides a chance to visit intermediate stations. Both trains maintain high standards of service with onboard facilities. Green Class offers enhanced comfort for those desiring more space during their journey.
