August is one of the most exciting months to visit Japan. It’s the peak of summer festival season, filled with energetic dances, dazzling fireworks, ancestral traditions, and regional celebrations that attract millions of visitors. From cultural rituals to vibrant street parades, August offers some of the most unforgettable experiences in Japan.

Here is your complete guide to the major Japanese festivals and traditions in August.


Obon is one of Japan’s most important spiritual traditions. It is a time when families honor their ancestors, who are believed to return to the world of the living for a short visit.

Typical Obon dates:

  • August 13–16 (most regions)
  • July in some parts of Tokyo and Okinawa

Key Obon traditions:

  • Bon Odori (traditional group dance)
  • Visiting family graves to clean and decorate with flowers
  • Lighting lanterns to guide spirits home
  • Family gatherings and special meals

Many towns host Bon Odori festivals, where anyone—including tourists—can join the circle dance.


Awa Odori is one of Japan’s biggest and most joyful festivals, attracting over a million spectators.

What makes Awa Odori special:

  • Energetic dance groups (ren) parading through the streets
  • Live shamisen, taiko drums, and flutes
  • Lively chants of “Yatto-sa! Yatto-yatto!”
  • Colorful traditional costumes

Visitors can also join beginner dance sessions. It’s one of the best ways to experience Japan’s summer spirit.


The Aomori Nebuta Festival is famous for its massive illuminated floats shaped like warriors, gods, and mythical creatures.

Festival highlights:

  • Enormous hand-painted lantern floats
  • “Haneto” dancers who shout “Rassera!”
  • Spectacular fireworks on the final day

If you want a festival that is both traditional and visually stunning, Nebuta is unforgettable.


Performers balance huge bamboo poles adorned with dozens of lanterns—some over 12 meters tall—using only their palms, shoulders, or hips.

This festival symbolizes a prayer for a good harvest and showcases incredible skill and strength.


While Tanabata is officially on July 7, many regions celebrate it in early August. Sendai hosts Japan’s largest Tanabata Festival.

Expect:

  • Beautiful paper decorations hanging from huge bamboo displays
  • Live performances and parades
  • Nighttime fireworks

The entire city becomes covered in vibrant colors and handmade ornaments.


August is the height of fireworks season in Japan, with shows happening almost every weekend.

Well-known August fireworks:

  • Nagaoka Fireworks Festival (Niigata) — one of Japan’s top 3
  • Omagari Fireworks (Akita) — national competition
  • Tokyo Sumida River Fireworks (late July or early August)

Japan’s fireworks are known for intricate designs and huge bursts that fill the sky.
