A Stroll Through Japan’s Hottest Record: Drawing “HOT” GPS Art in Isesaki✨
On August 5, 2025, Isesaki City in Gunma Prefecture marked Japan’s highest temperature ever recorded—an astounding 41.8°C—earning its place as the “hottest town in the country.” This 4km short walking route lets you commemorate that scorching moment by drawing the word “HOT” with GPS tracking. Starting from the meteorological observatory area, it’s an art experience that paints the heat directly onto the map.

The mix of everyday life and quaint scenery becomes the perfect backdrop for your GPS masterpiece. By the time “H-O-T” emerges on your map, you might just find the day’s heat a little easier to love.
Designed to be completed in a short distance, this course is perfect even in midsummer’s intense heat. Come experience Isesaki’s “heat” with all your senses in this one-of-a-kind fusion of digital art and real-world exploration.
