Traveling from Shinagawa to Fukuoka is best accomplished via the Shinkansen, specifically the Sakura and Mizuho services, which are part of the Nozomi family. The Mizuho Shinkansen is the faster option, reaching speeds of up to 300 km/h (186 mph) and completing the journey in approximately 5 hours and 10 minutes, with limited stops, offering a direct route to Hakata Station, Fukuoka's main station.
The Sakura service, although slightly slower, with speeds of up to 240 km/h (149 mph), takes around 5 hours and 30 minutes and makes a few more stops, including at cities like Hiroshima along the way. Both trains feature comfortable seating options with Ordinary and Green class accommodations available, allowing travelers to choose between economy and first-class experiences.
Amenities include onboard refreshments and spacious seating, ideal for long-distance journeys. The Mizuho service suits those prioritizing speed, whereas the Sakura provides a bit more accessibility with regional stops.
