Maglev Japan (リニアモーターカー) is a cutting-edge transportation system that uses magnetic levitation technology to achieve high speeds and energy efficiency. The technology has been under development in Japan for many years, and the country’s Central Japan Railway (JR Central) has been at the forefront of this innovation. Maglev trains are significantly faster than traditional trains, as traditional trains rely on friction between the wheels and tracks to move forward, which creates drag and limits speed. Maglev trains, on the other hand, use magnetic levitation technology to float above the tracks, eliminating friction and allowing for much faster speeds.
History
The development of Maglev technology in Japan began in the 1960s, with early research into magnetic levitation and propulsion. In the 1970s, the Japanese government began funding research into the technology, and in the 1980s, the first successful Maglev test track was built in Yamanashi Prefecture.
The ‘L0 Series Maglev’, which uses superconducting electromagnets to achieve magnetic levitation, was launched in 2015. The train set a new world speed record of 603 km/h (375 mph) during a test run in 2015. The train has since undergone extensive testing and is set to enter commercial service in 2027. The L0 Series Maglev will connect Tokyo to Nagoya, a distance of approximately 286 kilometers (178 miles), with a journey time of just 40 minutes. The train will travel along a route that is 90% underground, at speeds averaging around 505 km/h (313 mph).
How Maglev Japan Works
Superconducting electromagnets
Maglev technology uses superconducting electromagnets to achieve magnetic levitation and propulsion. The train has two sets of superconducting electromagnets; one set on the bottom of the train and the other set on the sides. These magnets interact with the guide track, which contains coils that are electrified to create a magnetic field. This interaction causes the train to float above the track, which reduces friction. The interaction between the magnetic fields of the coils and the magnets on the train creates a powerful force that propels the train forward at extremely high speeds.
Safety features
Maglev trains have several safety features, including sensors that detect obstructions on the track and automatic controls that slow down or stop the train if an obstruction is detected. The trains also have emergency brakes and redundant control systems to ensure passenger safety.
Energy efficiency
Maglev trains are also more energy-efficient than traditional trains. The lack of friction between the train and the tracks reduces energy consumption, and the regenerative braking system allows the train to recover some of the energy used during acceleration. Maglev technology has the potential to reduce carbon emissions and create a more sustainable future for transportation.
Construction Costs & Economic Benefits
The cost of building and maintaining a Maglev system is very high, due to the complexity of the technology and the need for specialized infrastructure. The Chuo Shinkansen (リニア中央新幹線) for example, is estimated to cost around 9 trillion yen (approximately 82 billion USD) to complete. This high cost has been a major point of contention for those opposed to the technology.
Despite the high cost, Maglev technology has the potential to create significant economic benefits, particularly in terms of reducing travel times and improving connections between cities. The Chuo Shinkansen is expected to create more than 400,000 jobs during its construction and will improve access to major cities like Tokyo, Nagoya, and Osaka.
Planned Routes and extensive use of tunnels
The Chuo Shinkansen will be built primarily in underground tunnels, which will minimize the impact on the surrounding environment and reduce noise pollution. The tunnels will be constructed using advanced tunneling technology and will be lined with a specialized concrete that is designed to withstand the high temperatures and pressures generated by the Maglev trains. Stations will be located at key points along the route.
Planned stations between Tokyo and Nagoya are as follows:
- Shinagawa (Tokyo)
- Hashimoto (Kanagawa)
- Kofu (Yamanashi)
- Iida (Nagano)
- Nakatsugawa (Gifu)
- Nagoya (Aichi)

Timeline for construction and completion
The construction of the Chuo Shinkansen is expected to take many years, with the Tokyo to Nagoya segment set to open in 2027, as previously mentioned. The Nagoya to Osaka segment is expected to be completed by 2045. The construction timeline is subject to change based on various factors, including funding and regulatory approvals.
Expansion plans beyond Tokyo – Nagoya – Osaka
Beyond the initial Tokyo to Nagoya and Osaka route, there are plans to expand the Maglev system to other parts of Japan. One proposed route would connect Tokyo to Sapporo, a distance of approximately 831 kilometers (516 miles), with a journey time of just over 3 hours. Another proposed route would connect Tokyo to Fukuoka, a distance of approximately 1,011 kilometers (628 miles), with a journey time of around 4 hours.
Opposition and criticism
Despite the potential benefits of the Maglev Chuo-Shinkansen project, there has been some opposition and criticism, particularly from Shizuoka Prefecture. The controversy centers around the impact on the local environment around the Tanna Tunnel, which is planned to be built under the Southern Japanese Alps.
Some local officials and community groups are calling for a reassessment of the project and greater consideration of the environmental impact. Despite the opposition however, the Chuo Shinkansen Maglev line is still planned to move forward, with construction already underway in some areas.
Heita Kawakatsu, the governor of Shizuoka Prefecture, has been a vocal opponent. He has been critical of the government’s handling of the project, calling for greater transparency and public engagement in the decision-making process. He has also expressed concerns about the high cost of the project and the potential for it to divert resources away from other important public priorities.
