Tokyo metropolitan government's Sewage Bureau spent about 34 million yen having a new set of badges made for staff uniforms after a problem was found with the logo on an original batch of 20,000. The new uniforms were ordered during the spring, after the design got a go-ahead from managers.

This was deemed a violation of the bureau's basic design manual, and new badges were subsequently ordered at a total cost of 34 million yen.
