A visitor can recognize Jeju’s haenyeo by their diving suits and floats without understanding the work behind the image. These women harvest seafood without breathing apparatus. Their culture also includes learning from other divers and knowing winds, tides and harvesting grounds. FAO describes that shared knowledge as central to the fisheries system. The Haenyeo Museum in Gujwa offers another entry point. Its special exhibition, ‘20 Years of Sumbisori, Capturing Memories of the Sea,’ uses objects, photographs, video and records gathered over two decades. Sumbisori is the breath made after resurfacing. Our reading is that an archive can shift the visitor’s attention from an impressive dive to the lives and communities sustaining it. This is living work, not just an inherited costume. In UNESCO’s 2023 interviews, divers describe family teaching, supporting other divers and environmental pressures. Those are individual accounts, not a survey of every village or current population figures. For a visit, the museum lists 09:00–18:00, with ticketing until 17:00, and regular Monday closures. A September 23 operator notice additionally identifies October 6, 2026 as a closure date. Recheck the operator’s notices before traveling. The exhibition does not promise a live diving demonstration. The museum’s guide-reservation page, checked October 1, states that guided commentary is offered only in Korean and must be requested three days in advance. This language limit applies to that guided service; English/Japanese exhibition labels and audio guides remain unverified.
