Combine your visit with a walk along the adjacent Shibukawa Beach for views of the Seto Ohashi Bridge.
Check the local tide charts if you plan to visit the outdoor exhibits or walk the shoreline nearby.
The facility is small, making it an ideal short stop rather than a full-day excursion.
Don't visit during mid-summer weekends if you want a quiet experience, as the adjacent beach attracts large crowds that can make parking difficult.
