The Shimoda Floating Aquarium, known locally as Shimoda Kaijū Suizokukan (下田海中水族館), is a distinctive marine aquarium constructed within a natural seawater environment. Unlike conventional aquariums, much of its structure, including the main dolphin habitat, floats directly in a protected bay. This unique design allows for a more expansive and seemingly natural setting for some of its larger inhabitants, particularly the dolphins, which are a major draw for visitors.
Visitors frequently highlight the captivating dolphin and sea lion shows as the main attraction. Reviewers consistently praise the close proximity to the animals during performances, noting that it feels more immersive than typical shows. Many appreciate the opportunity for direct interaction, such as feeding penguins, sea otters, and even dolphins (for an additional fee). The staff's enthusiasm and the apparent bond between trainers and animals are often commended, contributing to a friendly and engaging atmosphere. The jellyfish display also receives positive mentions for its beauty.
For a comfortable visit, plan to spend around 2-3 hours, which allows ample time to see the shows and explore the exhibits without feeling rushed. Weekdays are generally less crowded, offering a more relaxed experience. While the aquarium is suitable for all ages, families with children tend to enjoy the interactive elements the most. Consider bringing a light jacket, especially in cooler months or on windy days, as parts of the aquarium are exposed to the elements. Animal feeding opportunities are popular but often incur an extra cost, so budget accordingly if you wish to participate.
The aquarium is conveniently located a short walk from Shimoda train station. Reviewers mention a pleasant 500-700 meter stroll, which includes passing through a small tunnel under a mountain to reach the bay. Public transport is the recommended way to get there, as parking information is not consistently mentioned in reviews. The walk itself is described as scenic and straightforward.
A recurring concern among some visitors is the perceived small size of certain animal enclosures, particularly for the sea turtles and some penguins. Reviewers describe the sea turtle tanks as 'tiny' or 'kiddy-baths,' leading to strong negative reactions regarding animal welfare. While the main dolphin area is generally well-regarded for its spaciousness, those sensitive to animal confinement might find other exhibits distressing. To mitigate this, focus on the dolphin and sea lion shows, which are widely praised, and be aware that some smaller exhibits may not meet modern animal welfare expectations for all visitors.
