Nice catch! Hmm..., looks a lot like the entrance to Yokosuka Harbor.
I had my OK Scupper Pro TW with me when I did a C7F tour in 00-03. Launched out of the Yoko Yacht Club and fished the breakwater and out around Monkey Island. Caught lots of Aji, an occasional suzuki, and was routinely harassed by the local commercial fishermen.
