Riding the Shinkansen from Tokyo to Osaka

The train starts in Tokyo.

It rushes west past towns, fields and hills. It stops in the big city of Nagoya. Then it arrives in Osaka.

The Tokaido Shinkansen links Japan's three largest city areas: Tokyo, Nagoya and Osaka. Trains run west from Tokyo, through Nagoya, to Shin-Osaka station in Osaka.

The trains get their power from overhead wires, so they are electric. In fiscal year 2023, about 432,000 passengers rode the line each day.

JR Central describes the Tokaido Shinkansen as the transportation artery linking Japan's three largest metropolitan areas, Tokyo, Nagoya and Osaka, and credits it with supporting the country's economic growth. The trains are electric multiple units, drawing their power from an overhead wire system.

Beyond Osaka, the Shinkansen continues west to Okayama and to Hakata in Kyushu, and the fastest trains make the trip from Tokyo to Hakata in about five hours. For the Tokyo to Osaka trip itself, JR Central compares the train with air travel in energy use, as described below.

The Shinkansen can go 285 kilometers in one hour!

That is much faster than a car on the road. The fastest trains get from Tokyo to Osaka in less than two and a half hours.

When the line opened in 1964, the trains had a top speed of 210 km/h. Better tracks and trains have made them faster. Today, on the Tokaido Shinkansen, the maximum speed is 285 km/h.

The fastest trains travel from Tokyo to Shin-Osaka in 2 hours and 21 minutes (March 2023 timetable). That is less than two and a half hours for a trip of more than 500 km.

The original trains reached a top speed of 210 km/h. Improvements in track, rolling stock and other components have since raised maximum speeds across the Shinkansen network to between 240 and 300 km/h, and some trains on other lines began running at 320 km/h in 2013. On the Tokaido Shinkansen, JR Central gives the maximum as 285 km/h.

As of the March 2023 timetable revision, the fastest Tokyo to Shin-Osaka journey takes 2 hours 21 minutes. High speed requires careful engineering: Britannica notes that each car has brakes with cast-iron discs and metallic pad linings designed not to distort under emergency braking.

Shinkansen trains leave very often.

In busy times, a new train leaves every 10 minutes or less. Lots and lots of people ride every day. Each train has more than a thousand seats.

Between Tokyo and Osaka, trains leave very often. In the morning and evening rush hours, they depart at intervals of 10 minutes or less.

In fiscal year 2023, the Tokaido Shinkansen ran 372 trains a day and carried about 432,000 passengers a day. Each train has about 1,300 seats.

The line is named after the Tokaido, or Eastern Sea Road, an old highway that travelers used hundreds of years ago. The railway follows much the same route.

Frequency is the line's defining feature. Britannica notes that the most frequent service on the whole Shinkansen system is between Tokyo and Osaka, where trains depart at intervals of 10 minutes or less in the morning and evening rush hours. JR Central reports 372 train services per day in FY2023, including extra trains, and an average of 432,000 passengers a day.

Capacity per train is high: 1,318 seats, or 1,314 on the N700S type. Across the whole Shinkansen system, Britannica says, several hundred trains run each day. The line takes its name from the Tokaido (Eastern Sea Road), the highway used especially in the Edo period (1603 to 1867), which the railway generally follows.

Shinkansen trains are almost always on time.

In one year, they were only a tiny bit late on average. A control center in Tokyo keeps watch over every train.

In fiscal year 2023, the average delay on the Tokaido Shinkansen was just 1.6 minutes per train, and that includes delays caused by natural disasters.

JR Central says no passenger on board has been killed or injured in a train accident since the line opened in 1964. All train movements on the Shinkansen are watched and controlled from a central computer center in Tokyo.

JR Central reports an average delay of 1.6 minutes per train in FY2023, a figure that includes delays caused by natural disasters. It also states that there have been no accidents resulting in fatalities or injuries of passengers on board since operations began, and lists staff education and training and continual investment in safety-related facilities alongside that record.

Britannica explains part of the technical system: because of the high speeds, elaborate safety features were needed, and all train movements are monitored and controlled by a central computerized facility in Tokyo. The original line was built for the exclusive use of streamlined electric passenger trains.

The Shinkansen runs on electricity.

It uses much less energy than an airplane for each seat. It makes much less carbon dioxide, too.

Shinkansen trains are electric and can seat 1,000 passengers or more. JR Central compares the train with an airplane on the same trip between Tokyo and Osaka.

For each seat, the train uses about one-eighth as much energy as a plane. Its carbon dioxide emissions per seat are about one-twelfth of a plane's. Inside, the N700S type has 1,314 seats.

JR Central compares the Tokaido Shinkansen with aviation on the Tokyo to Osaka route: energy consumption per seat is approximately one-eighth that of an aircraft, and the CO2 emission rate about one-twelfth. These are the operator's own figures, given per seat.

The trains are electric multiple-unit sets that seat more than 1,000 passengers, 1,318 on standard Tokaido trains and 1,314 on the N700S. Combined with frequent service and a dedicated, high-capacity line, this is how the Shinkansen moves hundreds of thousands of people a day between Japan's largest cities.
