This natural history museum presents a variety of waterfront scenes, including a huge waterfall, a small stream, and an aquatic stage. It introduces the waterfront of the Akutagawa River, which flows through the center of Takatsuki City, through displays of freshwater fish ecology in large aquariums and diorama exhibits featuring models of birds and plants. There is also a wide selection of stuffed and specimen specimens of birds, mammals, and insects from Takatsuki City, allowing visitors to learn about the nature and history of Takatsuki.

Aquapia investigates, studies, and records the nature around us, and preserves the materials to pass them on to the future, working together with everyone involved in the museum ("everyone"). By sharing the results of our activities with as many "everyone" as possible, we hope to help people realize how closely nature is connected to our lives. We hope that by recognizing and correctly understanding the nature around us, and by connecting people through nature, we will come to love our communities and enrich the daily lives of "everyone." Aquapia aims to be a "museum" that helps make this a reality.
*When Aquapia thinks of "everyone," it refers to museum staff, visitors, volunteers, people who provide information about nature, and people who come to ask questions.
