Minabe Shougase is a deep boat wall dive in Wakayama where the draw is the marine life on the wall rather than an easy shoreline entry. The site is known for giant anemones and anthias at depth, plus clownfish and other macro life on the structure above them. It is part of a popular Minabe day-trip area with local operator support, so it fits best as a guided deep dive rather than a casual shore swim. Plan conservatively for depth, boat handling, and seasonal visibility swings.
