August is considered the height of Japan’s summer festival season, when the country bursts into color and sound. Nearly every region holds its own celebration, ranging from small neighborhood Bon-odori dances to massive, city-wide spectacles, like the Aomori Nebuta Matsuri.

In Tokyo, you might catch the Asakusa Samba Carnival, a fun parade blending Japanese flair with Brazilian rhythms. In eastern Japan, the Nagaoka Fireworks Festival in Niigata Prefecture is one of the largest in the country, lighting up the night sky with thousands of spectacular bursts. Kyoto hosts the Daimonji Gozan Okuribi on August 16, where giant bonfires shaped like Chinese characters are lit on surrounding mountains to send ancestral spirits back to the afterlife.

At many of the summer festivals, expect to see elaborately decorated floats, yukata-clad dancers moving in unison to folk songs, and food stalls offering a variety of summer street foods.

Especially for first-time visitors, viewing (and even joining) a local festival isn’t just a fun activity; it’s a great chance to connect with Japan on a different level and make a lasting memory.
