Biwako / Lake Biwa

is the biggest lake in Japan, at most points you can see only the horizon. my son keep on calling it the sea. 
for many years it was vastly polluted but action taken for many years and on going. have got the lake to a clean state. still some Invasive fish species are the cos of nature imbalance. most beaches are usually packed with people during July-August and sometimes you cant really see much with all the BBQ smoke. i personally love coming here during off season May to beginning of june or in Sep. if your lucky you might just have a privet beach.
