Katsura-hama is a popular beach 12km south of central K身chi at the point where K身chi's harbour empties out into the bay. Strong currents prohibit swimming, but it's a lovely spot to stroll, with a small shrine perched on an oceanside promontory. Just before the beach itself is Sakamoto Ry身ma Memorial Museum, with exhibits dedicated to the life of a local hero who was instrumental in bringing about the Meiji Restoration in the 1860s.
Public buses run to Katsura-hama from K身chi Station (?690, 35 minutes, six daily) and Harimaya-bashi (?620, 25 minutes, frequent). The My-Y迂 bus runs as far as Katsura-hama before heading back to K身chi.
