2026年8月2日(日)開催、箱根園湾を舞台にした夏の花火大会です。芦ノ湖の湖上から約3,000発の花火が次々と打ち上がり、周囲の山々に音が反響して体の芯まで響く大迫力を生み出します。静かな湖面に映る花火の光も見どころで、山あいの湖ならではのスケール感が楽しめます。標高が高い立地のため、真夏でも涼しい夜風の中で花火を見上げられるのも魅力です。

Tips

荒天時は中止または内容変更となる場合があるため、当日は主催者の発表を確認しましょう。終了後は駐車場や周辺道路が混み合うため、少し余韻を楽しんでからの移動がおすすめです。夜は冷え込むので羽織ものを忘れずに。

Tips

Located within the Hakone-en grounds, it's close to the ropeway station for smooth transfers. It's recommended to visit soon after opening during the summer vacation period, as it can get crowded.
