The journey from Nagoya to Aioi is served primarily by the Shinkansen, specifically the Hikari and Kodama services, both known for their reliability and speed. The Hikari Shinkansen typically reaches speeds of up to 285 km/h (177 mph) and can cover the distance in approximately 50 minutes, providing an efficient option for travelers. In contrast, the Kodama trains operate at a lower speed of around 110 km/h (68 mph) and take around 1 hour and 30 minutes to complete the journey, as they make stops at various stations, including Toyota and Aioi itself.
Both services offer comfortable seating with options for Ordinary and Green class, ensuring a pleasant travel experience. The Hikari Shinkansen is preferred for those looking to minimize travel time, while the Kodama train is ideal for passengers interested in sightseeing or making additional stops along the route. In summary, if speed is a priority, the Hikari Shinkansen is the best choice, whereas the Kodama provides a more leisurely travel pace.
