According to data from the Tokyo District Meteorological Observatory’s Climate of Tokyo and surveys by the Japan Meteorological Agency, Tokyo averaged 9.3 days of snowfall per year between 2022 and 2024. January records the highest average snowfall, with 3.7 days. Historically, the dates most likely to see snow are January 25 and March 8.

Snowfall in Tokyo does not always result in accumulation, but it can still cause major transportation disruptions. Because snow is relatively rare in the Greater Tokyo area, railways are not fully equipped with snow-melting systems due to the dense network of train lines and maintenance challenges.

When it snows, trains are forced to slow down and reduce service to prevent accidents. Snow removal relies heavily on manual labor, which is time-consuming and labor-intensive. Once snow reaches a certain level, restoring normal train operations can take a long time, making snowfall one of the main reasons traffic grinds to a halt in Tokyo.

The Japan Meteorological Agency is known for its high accuracy in forecasts. Before planning any trip to Japan, it's best to check their website for the latest weather updates! The website offers interfaces in Japanese and English, facilitating easy access for international travelers. Here, we also introduce some commonly used terms in Japanese weather forecasts.

The Japan Meteorological Agency's website offers more than just weather forecasts. It provides comprehensive data on rainfall, snowfall, snow accumulation, and historical weather information. When it comes to mobile apps, Japan has several weather apps available, such as the "Yahoo! Weather APP." Each app offers similar content, so choosing one based on personal preference and usage habits is advisable.

If there's a chance of snow during your travel period, it's wise to have multiple backup plans, like opting for indoor sightseeing/shopping or visiting attractions within walking distance from your accommodation to avoid the dilemma of being stuck on a train and unable to return to your hotel. Some attractions and businesses may close early due to snow, so keep that in mind. Additionally, if there's enough snow, building snowmen and having snowball fights outdoors can be great fun, just be careful not to disturb those around you who may be clearing the snow.

When planning your itinerary, check weather conditions online in advance. Before heading out, confirm with your airline that flights are operating normally, and consider travel insurance to cover unexpected situations.

While in Japan, stay updated by watching television broadcasts, checking airline websites, or following online news. Mobile apps for train operations are also useful for tracking the status of transportation services in real time.

If snow is forecast on your departure day, leave for the airport earlier than usual or consider changing your flight. Missing a flight due to snowfall can quickly turn into a major hassle.

Most train stations and platforms have electronic boards showing arrivals, destinations, and departure times. If no schedule is displayed, it often means delays or reduced service.

In more severe situations, station access may be restricted, or trains may depart without reaching their final destination after long waits. In such cases, adjusting your plans is usually the safer choice.

By using a train-specific route guidance app (like Navitime), not only can you check train schedules and transfer information, but you can also quickly grasp the current operating status of trains directly through the app.

Dress Warmly
Many people associate snow with extreme cold, but the chilliest moments often come when the snow starts to melt. Dress warmly when heading out, keeping in mind that indoor spaces and trains in Japan are well heated, so layering in an “onion-style” works best.

Protect exposed skin with gloves, scarves, beanies, earmuffs, or masks to reduce the risk of frostbite. Carry rain gear, switch to rubber-soled snow boots or shoes with anti-slip features, and consider rain boots if you are worried about wet feet. Heat packs are also a simple but powerful ally against the cold.

Walk Carefully
Staying warm is important, but so is watching your step. Snow that has partially melted or turned to ice can be extremely slippery, so walk slowly with small steps and keep your center of gravity slightly forward.

Keep your hands out of your pockets for balance, watch out for falling snow from rooftops, and avoid cycling when possible. If you are driving, use snow chains for better traction and reduce your speed.

And Don’t Forget These Tips!
Cold weather drains batteries faster than usual, so phones, cameras, and other devices may run out of power quickly. Carry spare batteries or limit outdoor use when possible.

Since hot drinking water is uncommon in Japan and hot water stations are rare, bringing a Thermos can help you stay hydrated. With the right mindset, extra time in your schedule, and a bit of flexibility, winter travel in Japan can still be safe, comfortable, and enjoyable.
