Govt to clean water in Tokyo Bay

Publication Date : 25-08-2014


Japan's Environment Ministry plans to clean up the water of Tokyo Bay as part of efforts to promote Japan’s environmental technology and natural scenery ahead of the 2020 Tokyo Olympic and Paralympic Games.

The ministry included about 3.6 billion yen (US$34.63 million) in its 2015 budgetary request for measures to help put on an Olympics that is sensitive to environmental problems.

Tokyo Bay is planned to be used for the swimming leg of triathlons at the Olympics, but the quality of the water declines during the summer.

Tokyo Gov. Yoichi Masuzoe has expressed concerns about such matters as the large amount of fecal coliform bacteria in the bay.

Therefore, the ministry plans to remove sludge, soil and sand from the bottom of the bay and experiment with using the mud to create wetlands to provide a home for a wide variety of living creatures. It also intends to prevent polluted water from flowing into the bay by improving its treatment facilities for household effluent.

The ministry further plans to clean the water in the outer moat of the former Edo Castle in Chiyoda Ward, Tokyo, which is close to an Olympic marathon course, as a preventive measure against the massive proliferation of blue-green algae and offensive odors from the moat.

In preparation for the many people who will visit Japan from overseas, the ministry also included in the budgetary request money to make national parks more accessible to foreigners by placing Western-style toilets in public lavatories and setting up signs in various languages.
