If you are a visitor at the Congres Center or tourist of Hamamatsu and looking for a running/jogging/walking route to the Pacific Ocean, this will suit the purpose. You will be passing nice lookin, suburbs of the city following the river/water systems. Very little traffic - you can pass the highway on small tracks. Don't count on swimming in the ocean - it is unfortunately too rough and in my opinion dangerous.
