Travelers journeying from Okayama to Atami can choose between the Sanyo Shinkansen and the Tokaido Shinkansen. The Nozomi service on the Tokaido Shinkansen is the fastest option available, reaching speeds of up to 300 km/h (186 mph) and covering the distance in approximately 4 hours and 30 minutes.

Both services feature Standard and Green class seating (Economy and First) to cater to different travel preferences. Onboard amenities enhance the experience, providing comfortable seating and food options for all passengers.
