Enjoy a leisurely afternoon rest and riverside scenery at a spacious park along the Mogami River

About this spot

This expansive park in Oe Town spreads along the banks of the Mogami River and features well-maintained grass fields and walking paths, making it an ideal place for families to spend time leisurely. You can get close to the river itself and enjoy the flow of the Mogami River and the countryside scenery up close. Under the summer sun, you can spread out a packed lunch and feel the cool breeze from the riverbank, or let children run around the spacious grounds—everyone can spend time as they wish. By taking time to carefully observe the Mogami River during daylight hours, which will be the stage for tonight's lantern floating and fireworks, your anticipation for the nighttime scenery increases even more. The park has abundant greenery and scattered shaded rest spots throughout.

Fireworks details

Name: 水郷大江夏まつり灯ろう流し花火大会

Date & time: 8/15 (Sat) 19:00–20:50

Venue: 大江町・最上川河川敷（楯山公園・千本原）

水郷大江夏まつり灯ろう流し花火大会は、終戦の日である8月15日に戦没者を偲んで最上川に灯ろうを流す行事と花火大会が合わさった、大江町の夏を代表する祭りです。川面を流れる無数の灯ろうの光は、夜の最上川を静かに、そして美しく彩ります。19時の花火打ち上げが始まると、灯ろうの揺らめきと花火の光が最上川の上で重なり合い、他の花火大会では味わえない独特の幻想的な光景が広がります。山形の里山に囲まれた最上川から打ち上がる花火は、川面に映り込みながら夜空に大きく開き、夏の夜の澄んだ空気の中に鮮やかな光の花を咲かせます。灯ろう流しに込められた祈りの意味を感じながら、家族で静かに花火を見上げる時間は、夏の大切な記憶になるでしょう。

Tips

荒天時の開催可否は大江町の公式発表で事前に確認してください。終了後は周辺道路が混雑するため、花火終了後は少し時間をおいてから移動するのがおすすめです。河川敷は照明が少ない場所もあるため、小さなライトを必ず持参してください。帰りの車・公共交通の時刻は事前に確認を。
