Project to Eliminate Blue-Green Algae at the Outer Moat of the Imperial Palace Hibiya, Tokyo

The Algae problem of the Imperial Palace Moat, Tokyo, has been reported on many occasions in the Japanese media, especially the Hibiya Outer Moat, which is the main focus of this project. Located at the water gate output point, it has a problem not only with Algae layers, but also odour in the main entrance of the Royal Palace. The Japanese Government investigated many solutions, but finally decided that Anzai Kantetsu Co. Ltd., should be involved in this project, using its patented nano-bubble technology.
