Tokyo Map: A Smarter Way to Explore Tokyo Safely

When visiting Tokyo, most travelers rely on familiar maps and navigation apps to find restaurants, train stations, tourist attractions, and hotels. But what if you could use a map to answer a different kind of question?

Where can I find water on a hot day? Where can I go to cool down? Or sometimes more pressing questions such as what areas could be affected by flooding? What should I know about earthquake risks around the places I am visiting?

For these kinds of questions, there is a useful resource provided by the Tokyo Metropolitan Government (TMG): Tokyo Map.

Web browser view of Tokyo Map

Until now, map information covering areas such as disaster prevention, the environment, digital services, welfare, and water services have been provided across the websites of different departments and organizations in the Tokyo Metropolitan Government umbrella. Finding information for a particular purpose therefore often meant visiting multiple websites. Since the full version release of Tokyo Map on August 20, 2026, with the collaboration of GovTech Tokyo (GTT), it has combined all these map resources together while allowing users to overlay multiple types of information on a single map.

How to Access Tokyo Map

Tokyo Map is a browser-based website that is free to use. To use it, simply open Tokyo Map in your preferred web browser, such as Google Chrome, Firefox, Microsoft Edge, Safari, or another browser, on your computer, tablet, or smartphone.

Accessible from desktops to smartphones

At present, Tokyo Map does not have an official version besides Japanese. International users can nevertheless use the site by taking advantage of the automatic translation feature available in many modern web browsers. When you open Tokyo Map, use your browser’s translation function to translate the page into English or your preferred language.

This can also be done on a smartphone. However, the exact steps and wording of the translation option vary depending on the browser and device so may need some tinkering on the users end to find. Most standard web browsers tend to have translation options readily available after tapping the options icon.

Stay Comfortable and Prepared

Different options available for customizing Tokyo Map to your needs

Tokyo’s hot and humid summers can be challenging for visitors and residents alike, but Tokyo Map can help you plan ahead. Its heat-related information includes the Tokyo WBGT Map to show heat stress levels and the risk of heat-related illness, Tokyowater Drinking Stations, facilities where people can take refuge from the heat, and the TOKYO GREEN BIZ MAP, which shows parks and other green spaces. Users can use these layers to check conditions around their destination and find nearby places to get water or take a break.

Tokyo Map also provides disaster-prevention information. The “Check your actions to prepare for an Earthquake” and “Check your actions to prepare for Flooding” themes bring together information such as earthquake damage assumptions, flooding and expected inundation areas, disaster-time water supply stations, and TOKYO FREE Wi-Fi. Flood maps also provide information such as expected water depth and the possible duration of flooding.

You do not need to study every map before your trip. Simply checking the area around your accommodation or a planned destination can give you a better understanding of your surroundings and help you know where to look if conditions change.

Stay Connected with TOKYO FREE Wi-Fi

If you have ever forgotten to buy a sims card or started to bump dangerously close to your data-limit before while traveling, you’ll know that having access to ready, free Wi-Fi can be a lifesaver. This is where Tokyo Map’s TOKYO FREE Wi-Fi locations come into action. Through the click of a button, locations with free Wi-Fi can be looked up while at a café or hotel room and then marked down so that while traveling about, you can have a general idea of where to stop if you need to check train schedules, translate some text you found, or search travel destinations.

This can be especially helpful for those who want to stay connected while keeping mobile data usage to a minimum or want a convenient place to reconnect while exploring.

Find Regular Spots to Cool Down

Particularly during Tokyo’s hot and humid summer, finding a place with air conditioning can make a huge difference to your every-day enjoyment of the city. Tokyo Map includes information on facilities where people can take refuge from the heat, helping those of us who may not do well after long periods under the sun to identify places where they can cool down and take a break.

By checking these locations before or during a day of leisure or sightseeing, you can build cooling breaks into plans rather than waiting until the heat becomes uncomfortable. Combined with the Tokyo WBGT  Map, drinking water locations, and other heat-related information, these features can help with planning a more comfortable day in Tokyo.

Find Barrier-Free Facilities

Tokyo Map also includes barrier-free information for wheelchair-accessible toilets. Visitors and residents can use the map to find locations around Tokyo and check available accessibility features. The information covers facilities at public buildings and railway stations, making it useful when planning sightseeing routes or choosing places to stop along the way.

Because this information can be viewed together with other map layers, users can, for example, check wheelchair-accessible toilets alongside heat-related information, Wi-Fi locations, or disaster-prevention information if they like to have a detailed plan in place before heading to their destination.

A Particularly Useful Feature: Ready-Made Themes

Three themes to quickly narrow down what’s important for you

One of the things you can do with Tokyo Map is freely combine 10 maps covering areas such as disaster prevention and the environment and view them together on a single screen. By overlaying different map layers, users can examine their destination from several perspectives.

Another particularly convenient feature of Tokyo Map is its ready-made themes. Instead of selecting individual map layers, you can start with a situation that interests you and see the relevant information together, allowing you to check the information you need at once.

“Protect Yourself from the Summer Heat”
•    TOKYO GREEN BIZ MAP
•    Tokyo WBGT Map
•    Tokyowater Drinking Station
“Check your actions to prepare for an Earthquake”
•    Tokyo Damage Assumption Digital Map
•    TOKYO FREE Wi-Fi
•    Disaster Water Supply Stations
“Check your actions to prepare for Flooding”
•    TOKYO FREE Wi-Fi
•    Flood Hazard Map
•    Disaster Water Supply Stations

These themes make it easier to explore Tokyo without needing to know which government agency provides each type of information. You can simply choose a theme, select your destination, and explore the information around it.

Tokyo Map: More Than Just a Map

Seeing how easy navigation can be using the browser translation

Tokyo has no shortage of maps and navigation apps. But Tokyo Map serves a different purpose. It brings together information that can otherwise be scattered across different government websites and lets users view multiple kinds of information together.

You might use your usual navigation app to find the fastest route to a destination, then use Tokyo Map to understand the environment around it. On a hot day, it can help you find water or a place to take a break. When planning a sightseeing route, it can provide useful information about the area. And if an earthquake, flood, or other emergency occurs, being familiar with Tokyo Map in advance can help you quickly access relevant information.

So whether you are coming to Tokyo for a short trip and would like quick information on the barrier-free facilities, water refill stations, etc. or you live and work in Tokyo and would like to plan more thoroughly with disaster preparedness information through earthquake and flooding statistics, Tokyo Map has you covered.
