A local resident contacted police at around 8:45 a.m. on Feb. 21 to report that she had found "a large, round object" on Enshuhama beach in Hamamatsu's Nishi Ward. Shizuoka Prefectural Police officers confirmed an iron ball-like object was on the beach. The force's bomb disposal unit X-rayed the ball, and found that it was hollow and not in danger of exploding. According to Hamamatsu Nishi Police Station, the apparently metal object's surface is brown with rust, and it has two protrusions that look like eyes for hooks, but little more about its nature is known. Part of its bulk is buried beneath the sand.
