Travelers on the Okayama to Akashi route can choose between the Shinkansen and the Special Rapid service. The Sanyo Shinkansen line features the Nozomi and Hikari trains, with the Nozomi reaching speeds up to 300 km/h (186 mph) and covering the distance in approximately 1 hour and 10 minutes, while the Hikari takes about 1 hour and 35 minutes due to additional stops. The Special Rapid service provides a slower option, with speeds around 120 km/h (75 mph), taking approximately 2 hours and 15 minutes to reach Akashi from Okayama.
Both the Nozomi and Hikari trains offer reserved and non-reserved seating options, making it easy for passengers to select their preferred travel style. Amenities such as free Wi-Fi, vending machines, and restrooms are available on board, promoting a comfortable journey. The Nozomi is best for those prioritizing speed, whereas the Hikari offers a slightly longer, yet comprehensive route to the Akashi area. If budget-conscious travelers are considering their options, the Special Rapid is a more economical choice.
