Traveling from Aioi to Shinagawa is primarily serviced by the Shinkansen (bullet train) network, notably the Nozomi and Hikari trains. The Nozomi Shinkansen provides the fastest option with speeds reaching up to 300 km/h (186 mph), covering the journey in approximately 1 hour and 30 minutes, with minimal stops. In contrast, the Hikari Shinkansen takes about 1 hour and 50 minutes to complete the same route, as it makes additional stops at cities like Okayama and Hiroshima.
Both train services offer Ordinary and Green class seating, allowing passengers to choose between standard and premium comfort levels. Travelers aboard the Nozomi enjoy quicker transit times at the cost of more limited intermediate stops, making it ideal for those on tight schedules.

Amenities on both trains include comfortable seating, onboard refreshments, and restrooms, ensuring a pleasant travel experience.
