Our family went Lake Kasumigaura where is the second largest lake in Japan and did a bike tour around the lake. There is also famous for Una-don, eel rice bowl, and of course we enjoyed it.
It was amazing because the lake was known as a contaminated lake for a long time ago, but now it becomes beautiful place and eel came back by the efforts of many many people.
Thanks for such people and we should keep its future.
