2026 Oishida Festival Mogami River Fireworks Festival Full-Day Course

This one-day course centers on the Oishida Festival Mogami River Fireworks Festival (大石田まつり最上川花火大会), held from 7:00 PM on Sunday, August 16, 2026, on the Mogami River bank (downstream of the Ohashi bridge) in Oishida Town, Yamagata Prefecture. At midday, walk through Oishida Kashi (大石田河岸), which retains the atmosphere of its Edo-period boat-transport heyday, then experience art at the Oishida Town Mogami River Art Museum (大石田町立最上川美術館). In the afternoon, enjoy cuisine unique to this soba-noodle-making town at the shopping street in front of Oishida Station, and in the evening, secure a spot and have dinner at Mogami River Furusato General Park (最上川ふるさと総合公園). As dusk falls, the riverbank fills with spectators as fireworks light up the night sky. This plan generously packs in a stroll through boat-transport history and fireworks in the night sky, making it a fitting way to close out summer in Oishida Town.
