The Hakodate Dynamite Summer Fest is a southern Hokkaido entertainment festival held every year over the three-day weekend that includes Marine Day in July, taking place throughout the city of Hakodate. With the motto “If it’s not fun, it’s not an event,” it’s loved as a lively summer festival that brings together music, activities, and food, and has been a staple of Hakodate’s summer since 2021. In 2026, it will be held from July 18 to 20 at Hakodate Green Plaza.

The Monbetsu Port Festival is a signature summer celebration of Monbetsu City, Hokkaido, originating from the prewar “Port Festival” and held annually since its first edition in 1955 to give thanks for the benefits brought by the Port of Monbetsu. Over 100 food and game stalls line the area around the former station-front street, and a wide array of events unfolds on the special stage and in the Honcho 4-chome pedestrian zone. The main highlight is the Okhotsk Fireworks Festival, which lights up the Okhotsk night sky. In 2026, it will be held over three days from July 24 to 26.
