Experience Oarai's Ocean at Japan's Largest-Class Shark Display and Black Tide Large Tank
About this spot
A representative aquarium of Ibaraki Prefecture where you can fully experience Oarai's Pacific-facing ocean. The facility's symbol, the "Black Tide Large Tank," is a powerful open space where rays and sharks glide gracefully, and the towering tunnel tank makes both children and adults pause in wonder. The shark display corner, boasting one of Japan's highest variety of species, is especially popular with children who love reference books. Dolphin and sea lion shows are held multiple times daily, allowing you to fully enjoy the afternoon before the fireworks festival. The facility features restaurants and comfortable rest areas throughout, so you can explore at a leisurely pace.
Fireworks details
Name: 大洗花火大会
Date & time: 9/26 (Sat) Time TBA
Venue: 大洗サンビーチ・東茨城郡大洗町
Shells: approx. 20,000
大洗サンビーチを舞台に繰り広げられる、約20,000発の大規模花火大会です。遮るものがない太平洋の広い空いっぱいに開く花火は、内陸の花火大会とはまったく違う開放感があります。海の上で炸裂する大輪の花火は音の反響も豊かで、砂浜に座って見上げると光と音が体全体に届く迫力。スターマインや尺玉など多彩なプログラムが夜空を彩り、フィナーレに向けて次々と打ち上がる連発は観覧客を大いに沸かせます。9月の夜の海風とともに楽しむ、大洗の1年で最も盛大な夜です。
