Jyonanto marine park was opened in 1991 with the facilities of camp ground, dog run, sandy beach and boardwalk, offering resort mood right in the middle of urban area. Air plane-watch can be enjoyed as it adjoins the Haneda airport. You can also gather shellfish at low tide at Tsubasa beach (approx. 440m).
For this project, we executed an artificial beach construction to recondition the beach that became sterile due to the erosion with our barge unloader, that is capable for this kind of work.
This technology is one of the important technologies for the seashore in Japan, where many beaches are getting sterile due to the dam and concrete revetment.
