The M135 Frogman was an underwater construction labor produced by Hishikawajima Heavy Industries. The airtight Frogman was capable of working underwater at depths of up to 50 meters. Thanks to its large air tank, the Frogman had a longer operation time than other labors that performed underwater work. When the Tokyo police’s SV2 labor tried to nudge a stray humpback whale out of Tokyo Bay, driver Hiromi Yamazaki was sent underwater in a Frogman to broadcast whale song and lure the whale out to the open sea. However, the effort proved ineffective because the whale was guarding her baby.
