While some regions in Japan, such as Hokkaido, may be less humid than others, the majority of the country experiences high levels of humidity at some point throughout the year. Visitors and locals should take precautions to stay hydrated and wear appropriate clothing. It's worth noting that Japan's humid climate allows for lush vegetation and stunning scenery, and many Japanese traditions have been developed to cope with the heat and humidity. Climate change may impact Japan's climate in the future, potentially making it even more humid.
