What ImaTetsu can do
1Real-time weather for every station
For every railway station in Tokyo, spatial completion technology estimates and displays the current weather. Check what the sky looks like "right now" before you head out.
2Comfort, expressed through a character
Sigmeow, a character whose expression changes with the weather, gently conveys how comfortable each station feels. Even if you're not familiar with weather details, you can grasp conditions intuitively.
3Signyaru's Weather-Based Sensations
On the "Nearby Station" and "Favorite Stations" cards, as well as the Tokyo weather section, Signyaru drops by with friendly comments! It shares how the weather actually feels at specific stations in an approachable tone.
Signyaru has two comment modes: "Normal Mode" and "Disaster Prevention Mode." When warnings or advisories are issued by the Japan Meteorological Agency, it automatically switches to "Disaster Prevention Mode" to deliver helpful caution messages.
4Top-Page Cards & Precipitation Forecasts
The top page features card-style displays for nearby stations (via GPS) and your saved favorite stations. Each card includes a "1-Hour Precipitation Forecast" graph, allowing you to instantly see when rain will start or intensify.
Note: You can view your list of favorite stations anytime from My Page.
5Sora MAP (Real-time Weather Map)
"Sora MAP" lets you view Tokyo's overall weather conditions (such as temperature and precipitation) on a color-graded map. It helps you get a broad overview of weather patterns along your daily commute or at your destination.
6Rain MAP (Precipitation Forecast Map)
"Rain MAP" visualizes the movement of rain over the next hour (precipitation intensity) based on real-time rainfall data. Combined with the simplified graphs on the station cards, it helps you avoid sudden rain and time your movements better.
It's an indicator of rain strength, showing how much rain is expected to fall in one hour. Higher numbers mean heavier rainfall.
