The Kamakura Swimming Association holds the Japan Swimming Federation-certified swimming ability test three times a year. Successful applicants will receive a swimming ability certificate and badge from the Japan Swimming Federation.
One of these events is held as a special swimming ability test (Nichirei Challenge) after application and approval was obtained from the Japan Swimming Federation. Here, Olympians provide model swimming techniques and one-point instruction to help improve swimming ability, and many people have passed the exam. After the competition, each Olympian receives encouragement from the Olympians, presents them with a certificate, and holds a photo and autograph session, which is gaining popularity as it increases motivation for the next time.
