Kashiwajima and Tatsucushi Coast: Transparent Blue Sea and Submarine Observatory Tour

A scenic all-sea driving date course through Tosashimizu City and Otsuki Town at the southwestern tip of Shikoku in Kochi Prefecture. In the morning, meet the sea creatures of Ashizuri at Ashizuri Marine Museum SATOUMI on Tatsucushi Bay, then take a scenic walk around the Tatsucushi Coast's rock formations carved by waves and wind. At the Ashizuri Submarine Observatory, where you can peek underwater while fully clothed, colorful fish come right up to the window at 7 meters depth. In the afternoon, experience the highly transparent blue sea of Kashiwajima Island, where boats are said to appear floating in the air. The time spent gazing at the crystal-clear sea together will surely become an unforgettable memory. The finale is a late lunch at Michi-no-Eki Otsuki and the signature sweets. An aquarium, rock formations, underwater viewing, and breathtaking beach—a greedy full-day sea tour immersed in "blue" throughout.
