As we followed the tourist path, we found something there that was very sobering and very interesting to these American tourists' eyes and hearts.
We visited a peace park on Okinawa's main island. It had once housed the Imperial Japanese Navy's underground command center, which was finally overrun by the American invasion of Okinawa near the end of World War II.
It contained a set of intricate tunnels and historic displays of photographs, information, and furnishings, meticulously preserved and maintained as a dedicated national peace park.
This downward and dimly lit staircase sort of gives a sense of the general mood down there.
