Begin your afternoon stroll at the park where historic Gion Castle ruins remain
About this spot
Shiroyama Park (城山公園), located in the central part of Oyama City, is a historic park that was developed from the ruins of Gion Castle (祇園城跡), which was built by the Oyama clan in the Muromachi period. The remains of earthen walls and moats are preserved throughout, allowing visitors to walk while feeling the weight of history. The spacious gardens are filled with trees, and in early October, the autumn greenery is pleasant, making it ideal for families to take leisurely walks. You can also feel the flow of the adjacent Omokawa River, and experience the atmosphere of tonight's fireworks venue during the daytime. There are also open grass areas where children can run around, making it perfect for a digestion walk after lunch.

おやまサマーフェスティバル（小山の花火）は、栃木県小山市の思川河畔を会場に開催される、約20,000発を誇る北関東有数の大花火大会です。広い河川敷から打ち上げられる花火は遮るものがなく、夜空の高いところまで大輪が開く迫力は格別。秋の澄んだ空気の中で見上げる花火は、夏の大会とは異なる凛とした美しさがあります。川面に映る光の帯と、体に響く花火の音が一体となる河畔観覧ならではの体験は、1日の締めくくりにふさわしいクライマックスです。家族でこの瞬間を共有した記憶は、きっと長く心に残るでしょう。
Tips
荒天時の開催可否は大会公式発表や小山市の情報で確認してください。終了後は会場周辺の道路と駐車場が大変混雑します。フィナーレ後は河畔でしばらく余韻を楽しんでから移動する時間差帰宅がおすすめです。小山駅への帰りは臨時バスや徒歩ルートを事前に確認しておきましょう。足元が暗い場所があるため、ライトを忘れずに。
Tips
About 15 minutes walk from Oyama Station (小山駅), or a few minutes by bicycle or car. Admission is free. Check the locations of restrooms and parking lots in the park in advance, as this information will be helpful for your return trip at night. It's efficient to have lunch near the station or close to the park before heading to this location.
Best time to visit
Approximately 1 hour 15 minutes required. From mid-morning to early afternoon in October, the sunlight is gentle and ideal for strolling.
