Why is the Shinkansen so quiet?

The train's tilting mechanism to lean into curves at high speed and the high-quality airtight body minimize vibration and provide a smooth, quiet ride.



The Shinkansen, or Japanese "Bullet Train," is engineered for silence using advanced aerodynamics and noise-dampening technology. The most striking feature is the long, bird-beak-shaped nose, designed to prevent "tunnel boom"—a loud shockwave caused by air displacement when entering tunnels at high speed. The trains also use low-noise pantographs (the arms that collect electricity) and sound-absorbing "skirts" along the sides to muffle track noise. Additionally, the tracks themselves are built on high-quality concrete slabs with heavy-duty noise barriers lining the routes in residential areas. Inside the cabin, an airtight body and advanced suspension systems minimize vibration, creating an environment so quiet that passengers are expected to follow "manner mode" customs, such as speaking in hushed tones and keeping phones on silent. In 2026, the newer N700S models have further refined these features to provide the smoothest, quietest rail journey in the world.

Not Being Noisy on the Train is an Iron Rule There is no rule against talking in the train car, but if your conversation is loud enough to be heard by those around you, it is considered rude and annoying. Japanese consider discussing private matters in public to be unseemly and rude.

Talking loudly on trains is considered bad mannered and ranks highly amongst the most annoying behaviors on trains in Japan. Don't talk on the phone. Only on long-distance trains on the decks between cars is talking on the phone acceptable. Set your phone to silent mode.

In Japan, the high-speed Shinkansen trains spray water onto snowy tracks to prevent the snow from blowing up into the undercarriage and re-freezing. In all areas with extreme winter conditions, de-icing, like in the airline industry, is essential.

Eating and drinking on Japanese trains You should eat on trains only when taking a long-distance train, such as the Shinkansen. These types of trains have a tray and cup holder at every seat, and snacks are sold from a vendor trolley. When taking this type of train, it is also acceptable to bring your own food.

The ATC system prevents high-speed passenger train-on-train collisions and excessive speeds. The advanced ATC system exercises complete control over the entire dedicated track and every operating train, preventing train-on-train collisions and excessive speed.

Big pressure changes outside the train can have an effect in the carriages themselves, particularly where there's not much clearance between the top of the train and the roof of the tunnel. This is why your ears sometimes pop when travelling through tunnels at high speed.

Kodama (???, Echo) is one of the three train services running on the Tokaido and San'yo Shinkansen lines. Stopping at every station, the Kodama is the slowest Shinkansen service for trips between major cities such as Tokyo and Osaka.

No, The Shinkansen which is Japan's bullet train rail network, has never had an accident in its 59-year history. In case of earthquake, Shinkansen operation is stopped immediately when the seismometers detect the primary wave of an earthquake.

Yes, not only is it ok, but they actually sell beer on the trains. Originally Answered: Is it ok to drink alcohol on the Shinkansen? Don't they sell beer and sake on the Bento trolley that goes down the aisles? Yes, its OK to drink on the train.

The Glacier Express is the world's slowest train, taking more than eight hours to travel between Zermatt and St. Moritz in Switzerland at an average of 18mph. Along the way, it passes over nearly 300 bridges, travels through 91 tunnels and takes in endless stunning Alpine views.

Rail in the US is dominated by freight movements, the passenger sector is very much and afterthought and doesn't receive much investment. As a result their lines are slow, dominated by freight, and their rolling stock is old and low tech. Japan, in contrast, has one of the best and most modern railways in the world.

MORE DETAILS

Most trains do not operate 24 hours; for example, in Tokyo they do not run in the early morning 01:00-05:00, and the Shinkansen never runs overnight. If you are planning to be out late and are relying on the train to get home, be sure to find out when the last train is leaving.

When riding the Shinkansen or on a long train ride in a green car (reserved seating) you are allowed to eat and drink. The seats actually have tables and cup holders. There are also food, drinks, and snacks being sold in these train cars. But on commuter trains, avoid eating.

Firstly, the design of Shinkansen trains emphasizes safety and performance, rather than aesthetics. The smaller windows reduce the risk of shattering in the event of an earthquake or a collision, which is a significant concern in Japan due to its frequent earthquakes and mountainous terrain.

The early earthquake warning system detects a P-wave (Primary Wave) of an earthquake, alerts the control center that there is an earthquake coming. Within seconds, the power of the overhead wire of the Shinkansen will be cutoff. Shinkansen relies current on the track to detect railway signals.
