A family and couple-friendly amusement park and aquarium integrated park, located in Yokohama, Kanagawa, Japan. It takes about an hour by car from Tokyo via the highway. It is a seaside amusement park with four aquariums and various attractions such as white-water rafting, roller coasters, mazes, and rotating games for children. As it is an island, visitors can row their own boats or take a boat ride to enjoy the scenery. The focus is on the aquariums, with four of them rotating various performances. My child loves watching dolphin shows the most. There are also light shows in the evening, as well as dolphin feeding, touching and interacting with dolphins, but reservations are required in advance. If you don't want to go outdoors in the summer, you can just buy tickets for the aquarium. There are also all-inclusive tickets, but I recommend buying individual tickets because it's hard to experience everything with a lot of people. The aquariums are all indoors and not hot, and the various sea animal performances are very entertaining. There is also a small zoo with some animals that can be touched and children are very excited about it. There are also food options available, averaging around 1000 yen per person. Going in the morning and returning in the evening allows visitors to enjoy many attractions without getting bored. Highly recommended!
