Traveling from Odawara to Nagoya can be efficiently accomplished using the Shinkansen services. The primary train serving this route is the Hikari Shinkansen, which operates at speeds of up to 285 km/h (177 mph). This service typically makes fewer stops compared to local trains, allowing for a travel time of approximately 2 hours and 30 minutes to 3 hours, depending on the specific service chosen. The Hikari makes scheduled stops at major stations such as Yokohama and Nagoya, providing access to those key locations. Additionally, the Kodama Shinkansen operates on the same route, which is slightly slower, reaching speeds up to 240 km/h (149 mph) and stopping at more stations, resulting in a longer journey time of around 3 to 4 hours. Both services feature comfortable seating options in Ordinary and Green classes, ensuring a pleasant trip for passengers. For travelers prioritizing speed and less frequent stops, the Hikari is the superior choice, while those looking for regional access might prefer the Kodama.
