Summer in Japan wouldn't be complete without hanabi taikai (firework festivals). From spectacular riverside displays and centuries-old traditions to unique handheld fireworks and castle backdrops, the Tokai region offers some of Japan's most memorable summer events. Whether you're based in Nagoya or exploring Aichi, Gifu, and Mie prefectures, these festivals are well worth adding to your itinerary.

The highlight is an enormous 600-meter-wide Star Mine that stretches across the river, while giant shells burst overhead against the backdrop of Mt. Kinka and Gifu Castle.

Nagoya Port Festival (Minato Matsuri) (Nagoya)
Date: July 20, 2026 (Monday, National Holiday – Marine Day)
The Nagoya Port Festival (Minato Matsuri) is one of Nagoya’s most beloved summer celebrations and has been welcoming the arrival of summer every year on Marine Day (Umi no Hi). First held in 1946 to help restore community spirit following World War II, the festival has grown into a major waterfront event that brings together local traditions, entertainment, and spectacular fireworks.
Throughout the day, visitors can enjoy parades, traditional performances, community Bon Odori dancing, and various stage events around Nagoya Port. As evening arrives, the festival reaches its climax with a dazzling fireworks display over the harbor, featuring synchronized music, colorful lighting effects, and large-scale fireworks reflected across the water.
One of the most unique parts of the festival is the log rafters’ contest, a traditional event that celebrates Nagoya’s historical connection to the timber trade. During the Edo period, Nagoya Port played an important role as a distribution center for wooden logs used in the construction of castles, temples, and shrines throughout Japan. In this exciting competition, participants balance on floating logs and compete to see who can remain standing the longest without falling into the water.

Maruyama Senmaida Insect Repelling Festival (Kumano, Mie)
Date: Early June
One of the Tokai region's most enchanting early summer traditions takes place at Maruyama Senmaida, widely regarded as Japan's most beautiful terraced rice fields. Nestled in the mountains of Kumano, the landscape consists of approximately 1,340 tiny rice paddies cascading down the hillside. Their intricate layout has inspired the local saying, "If you think one rice paddy is missing, it's simply hidden beneath your hat."
The Insect Repelling Festival (Mushi Okuri) is a centuries-old agricultural ritual held each year to pray for a healthy rice crop and a plentiful autumn harvest. As dusk falls, the peaceful rice terraces are transformed into a magical sea of light when 1,340 candles—one for each rice paddy—are illuminated. Volunteers carefully relight any candles extinguished by the evening breeze, creating a mesmerizing glow that ripples across the mountainside.
At 7:00 p.m., the festival's most important ceremony begins at nearby Maruyama Shrine. Led by an amulet blessed at the shrine, a procession of local children carrying flaming torches walks through the narrow paths between the rice fields. Accompanied by the rhythmic sound of drums and bells, they chant, "Here comes the insect-repelling lord!" as they carry the protective amulet to the highest rice field, symbolically driving away harmful insects and ensuring a successful harvest.
Once the amulet has been placed, a rocket firework is launched into the night sky to announce the successful completion of the ritual. The children return through the glowing terraces to warm applause from spectators gathered throughout the valley.
The evening concludes at around 8:00 p.m. with the firing of ceremonial cannons, signaling the end of the festival. As darkness settles over the mountains, visitors linger to admire thousands of candle flames flickering among the terraced fields—a breathtaking scene that beautifully reflects Kumano's deep connection to nature, agriculture, and local tradition.

- Location: Maruyama Senmaida, Kumano City, Mie Prefecture
