Panoramic views of Tokyo Bay Aqua-Line from observation tower

About this spot

An observation tower built on an elevated site overlooking Kisarazu Harbor is the park's symbol. From the observation floor, you can see Kisarazu Harbor, Tokyo Bay Aqua-Line, and on clear days, even the opposite shore toward Kawasaki and Mount Fuji - one of Kisarazu's finest viewpoints. The park is surrounded by greenery, and you can play and exercise below the tower. It's also recommended to view the direction where this evening's fireworks will light up the sea in daylight.

Fireworks details

Date & time: 7/20 (Mon) 20:30– ※7/22 (Wed)まで毎晩開催

Venue: 木更津市・龍宮城スパホテル三日月

東京湾に面した龍宮城スパホテル三日月で行われる、海上花火のショーです。2026年7月20日(月)から22日(水)までの3日間、毎晩20時30分から花火が打ち上がります。ホテルのシンボルである竜宮城をイメージした建物を背景に、東京湾の海上から花火が上がる様子は、木更津ならではの夜景です。海面に映る花火の光も見どころのひとつです。周辺のホテル利用者だけでなく、近隣からも花火を目当てに訪れる人がいる、木更津の夏の風物詩です。

Tips

打ち上げ時間や実施の有無は天候により変更となる場合があるため、当日はホテルの発表を確認しましょう。周辺は夕方から車が集中しやすいため、時間に余裕を持って移動するのがおすすめです。終了後は帰りの道が混み合うことがあるので、少し余韻を楽しんでからの移動も一案です。
