On the Atami to Okayama route, travelers typically have access to the Shinkansen services, which include the Nozomi and Hikari trains. The Nozomi Shinkansen is the quickest option, cruising at speeds up to 300 km/h (186 mph) and covering the distance in approximately 3 hours and 50 minutes, with fewer stops primarily in major cities like Nagoya and Osaka. On the other hand, the Hikari Shinkansen also serves this route but takes around 4 hours and 10 minutes due to additional stops, providing access to smaller stations along the way.
Both services offer comfortable seating arrangements ranging from Ordinary to Green class, catering to different travel budgets and preferences. Passengers can expect amenities such as spacious seating, power outlets, and onboard refreshments. The choice between Nozomi and Hikari largely depends on whether the traveler prefers a faster journey or is looking to visit more regional areas during their trip.
