Why hotter or colder than the forecast?
Then the perceived temperature may be more practical for Tokyo. So ℃ocochi was created.
℃ocochi informs you of the perceived temperature using figures, colors, and voice
based on updated meteorological data. Take a look before going out or receiving guests.

℃ocochi retrieves meteorological data from the internet, using a Heat Index^*
developed specifically for Tokyo to display the perceived temperature.

Tokyo Heat Index (for ℃ocochi only)

（℃）

Developed from the historical highest (49.8℃) and lowest (-7.3℃) percieved temperatures in Tokyo.

The perceived temperature is also indicated by colors as adopted by the US National Weather Service. So you can grasp the perceived clearly and intuitively without feeling at odds with the actual temperature. The perceived temperature is also effective for heat stroke prevention.

* ℃ocochi is a prototype.
