Build a new one. I’ve been there several times. It reminds me of the Civil War cemeteries and battlefields that I’ve also visited. Quiet and reverent. I took my Grand Parents and two of their friends there in 1979. Grandparents were respectful and their friends were loud and obnoxious. Grandparents and I talked about this and I never saw their friends again.
I’ll always remember the quiet.
I also went in 1979, with my Mom and one of my brothers, a Marine. It was solemn, until a loud group appeared. Everyone glared at them until they left. I wonder how often that happens.
I visited a few times when I lived in Hawaii in 2010-11. There were more Japanese tourists than US citizens on each visit.
