Spend your summer with Sumikkogurashi at Aqua World Oarai

We will be holding a collaboration event with "Sumikko Gurashi," a character immensely popular with people of all ages, from children to adults, from July 16th (Thursday) to September 23rd (Wednesday/Holiday), 2026. This year marks the fourth consecutive year that we have held this event, and we will be offering a variety of activities, including a special exhibition focusing on the "tails" of various sea creatures, "The Tails of the Sea Exhibition," as well as the annual in-house rally, collaborative food, and collaborative merchandise sales. Enjoy a special time discovering new charms of living creatures together with the Sumikko characters.
