Think about life by seeing Lake Biwa

Lake Biwa reflects our lives. We learn a lot from experiences such as the red tide problem and the soap movement, so let’s keep on working hard to protect and corporate with Lake Biwa for our future.

Think of Lake Biwa - July 1st ” Lake Biwa day” -

In 1977,a large-scale freshwater red tide occurred caused by excessive growth of the phytoplankton and the people of Shiga initiated a movement to use natural soap instead of detergents containing phosphorus.
Supported by the citizen’s great movement for saving Lake Biwa, Shiga Prefecture put the Ordinance for the Prevention of Eutrophication of Lake Biwa into effect ont July 1, 1980.
In the following year, July 1 was designated as ”Lake Biwa Day”. Many events and activities have been held to remind people of the importance of the Lake around Lake Biwa Day every year.
Let’s keep the soap movement int mind and keep working on what we can do to live in prosperity with Lake Biwa.
