Okazaki Castle Town Ieyasu Summer Festival: 78th Fireworks Display

Summary

Okazaki, the birthplace of Tokugawa Ieyasu, marks summer with its 78th fireworks display on August 1, 2026. The tradition traces to Edo-period festivities at Sugo Shrine, when decorated festival boats floated on the river, and the event today supports the continuation of Mikawa fireworks, the city's traditional craft. The banks of the Oto and Yahagi rivers host the show for 90 minutes from 19:00; the shell count is not published. Paid seating and traffic updates are posted on the official site, and Higashi-Okazaki, Okazaki-Koenmae or Nakaoka stations are each a ten-minute walk away.

Overview

The 78th Okazaki Castle-Town Ieyasu-ko Summer Festival fireworks fill the banks of the Oto and Yahagi rivers in Okazaki, Aichi, on August 1, 2026, running 90 minutes from 19:00 to 20:30. Rooted in the Sugo Shrine festival of the Edo period, the event carries the Mikawa fireworks tradition forward as the centerpiece of the castle town's summer. The shell count is unpublished. Arrive on foot from Higashi-Okazaki or Okazaki-Koenmae on the Meitetsu line, or Nakaoka on the Aichi Loop Railway — all ten minutes away; there is no parking at the riverside, so trains are the baseline. Check the official site beforehand for paid-seat guidance and day-of traffic notices, and decide which riverbank to enter in advance.
