Osaka City Sewerage Science Museum

The Osaka City Sewerage Science Museum is a science museum focused on wastewater systems and urban water infrastructure located in Takami. Exhibits spread across multiple floors and use interactive displays to explain how sewage is treated and how these systems support city operations.

The museum opened in 1995 to commemorate 100 years of modern sewage operations in the Osaka region. It was built at the location of an existing treatment plant that itself represents decades of urban water management development.

The exhibits show how sewerage systems shape daily urban life and connect people to the engineering that keeps cities functioning. Visitors see the invisible infrastructure that makes modern living possible and discover the pride local engineers have in solving practical problems.

The museum is free to enter and easily accessible, making it a welcoming place for all visitors. The exhibits are designed to be interactive, allowing you to engage directly rather than simply reading information.

The top floor contains a heated botanical garden where plants grow in water without soil using heat and water produced by the treatment process. This demonstrates a practical way the facility recycles its own resources.
