With flu season in full swing, here’s what travelers need to know before visiting Japan

Japan remains one of the world’s safest travel destinations, but like anywhere, it comes with seasonal risks—especially in winter, when flu and norovirus cases spike. Crowded trains, busy tourist attractions, and indoor heating all contribute to the rapid spread of infections.

However, Japan’s strong culture of hygiene, like frequent handwashing, mask-wearing, and the use of antiseptic mouthwash, offers valuable lessons for travelers looking to stay well. Simple habits, smart precautions, and local knowledge can make all the difference.
