Flow of the course
About this spot
The Okazaki Castle Town Ieyasu-ko Summer Festival Fireworks Display is a festival representative of an Okazaki summer, with fireworks launched from two locations: the bank of the Otogawa River (乙川) and the bank of the Yahagi River (矢作川). The sight of light reflected on the river's surface overlapping with the night view of the castle town associated with Lord Ieyasu is a scene unique to this event. From the launch's start at 19:00 to the finale at 20:30, the fireworks that keep coloring the summer night sky can be enjoyed with full impact from any area along the river. Another feature of this event is that the two venues, the Otogawa and the Yahagi, each offer launches from different angles. The moment the finale's barrage dyes the castle town's night sky is a sight fitting for the climax of the day.

Check Okazaki City's official announcements before the event for paid seating and free viewing areas. In case of bad weather, the event may be canceled or postponed, so check official information on the day for whether it will proceed. Afterward, the routes back to Meitetsu Higashi-Okazaki Station and JR Okazaki Station become extremely crowded. It's reassuring to wait a while after the finale before moving, or to research a route in advance that avoids the crowds. Some areas underfoot are dark, so carry a light.
