Lake Hamana – A large ‘Ocean Lake’ full of surprises

Lake Hamana in Shizuoka is a large brackish lake that stretches inland from the coast with a unique ecosystem that provides a wide variety of experiences & activities. 

It was a freshwater lake until a 1498 earthquake that connected it to the Pacific Ocean, so it is technically a lagoon.

The water in Lake Hamana is brackish. It means the water is a mix of salt water from the Pacific Ocean and fresh water that flows down from the Japanese Southern alps. Therefore, the lake water does not have the same amount of salt content as the ocean.
