2026 Makado Sea Marine Park (Saltwater Aquarium at Yokohama Municipal Makado Elementary School) Full-Day Course

Makado Elementary School in Naka Ward, Yokohama, is home to Makado Sea Marine Park (まかどシーマリンパーク), a saltwater aquarium that is a rarity for an elementary school. It is not open year-round; you can visit during public open houses held several times a year on Saturdays (for example, June 6 and July 11 in the 2026 school year, 9:30-11:30), and admission is free. Meeting sea creatures inside a school is a unique experience that will be an unforgettable memory for children. Open-house dates are announced on the school website, so be sure to check before planning your trip. Since the open house is in the morning, start your day with a scenic walk at nearby Honmoku Sancho Park (本牧山頂公園). After the open house, spread out a picnic lunch at a park in the Honmoku area for a full day of fun.
