Lay out a leisure sheet in the riverbed and wait for the show, savoring the river breeze and sunset
About this spot
A green space developed along the Mogami River's riverbed and the main viewing area for the Nagai Water Festival Mogami River Fireworks Display. Spread out your leisure sheet along the expansive lawn embankment, and wait for the display while gazing at the Mogami River flowing before you. As the sun sets, the river's surface changes color moment by moment, and the silhouettes of the mountains on the far bank emerge—the twilight hour is another joy before the fireworks. Food stalls and vendors line the area around the venue, allowing you to experience the festive atmosphere firsthand. When night falls, a cool breeze blows along the riverside, so keep a light jacket handy for peace of mind.
Fireworks details
Name: ながい水まつり 最上川花火大会
Date & time: 8/8 (Sat) 19:30–
Venue: 長井市・最上川河川緑地公園
Shells: approx. 3,500
2026年8月8日(土)19時30分開始、ながい水まつりのクライマックスを飾る最上川花火大会です。最上川の川上から打ち上がる約3,500発は、山形の大河・最上川の川幅いっぱいに広がり、川面に映る光の揺らぎとともに夜空を彩ります。川沿いの会場は周囲の建物が低く視界が広いため、大きな花火を遮るものなく正面から楽しめるのが最大の魅力です。山形の夏祭りの伝統を受け継ぐ水まつりの夜は、地元の人々と一緒に川の風と花火の音に包まれる、旅の忘れられない1ページになるはずです。フィナーレの連発が川と空を同時に照らす瞬間を、家族全員でじっくり見届けましょう。
Tips
荒天時の開催可否は長井市・長井商工会議所の公式発表で必ず確認してください。終了後は会場周辺の道路と長井駅方面が混雑するため、フィナーレ後は河川敷でしばらく余韻を楽しんでから移動するのがおすすめです。フラワー長井線の帰りの電車時刻は事前に確認しておきましょう。足元が暗いので小さなライトがあると安心です。
Tips
On the fireworks festival day, crowds increase from around 6 PM, so secure your spot by no later than 6:45 PM. Use restrooms before the show starts as they get crowded. After the display, expect heavy congestion during departure, so it's easier to enjoy the moment a while longer before moving.
Best time to visit
Approximately 40 minutes required. Slowly enjoy the color changes of the river around sunset.
