Mr Watanabe Shinya, a first grade office of the Nippon Coast Guard office in Obama City, has devised a simple and inexpensive floating harness that can be used to retrieve Crew Over Board (COB).
The harness is made from a length of 3-strand laid
rope, a polyethylene pool noodle, and a snap shackle. The cost is low: a few US dollars, a few hundred Nipponese yen.
Mr Watanabe designed the harness solve the problem of winching aboard a vessel a COB without injurying the COB. The COB must be either: (1) conscious and able to help themself into the harness; or (2) assisted into the harness by a swimmer. The need for the harness was demonstrated in an incident in which a simple
rope harness was used to
winch a COB aboard, but which caused injuries.
The harness has so impressed Nippon Coast Guard that they are recommending
fishing boats and pleasure craft to carry one. The harness is called the "Anshinya" for convenient reference.

The Tsuruga station of the Nippon Coast Guard has placed a pdf with instructions for making two versions of the Anshinya - a three section harness (with two eyeloops, either of which can be used for winching aboard); and a four section harness (with three eyeloops, either of which can be used for winching aboard). The eyeloops provide convenient lodgements for a boathook, so the 4-section Anshinya might be better.
For your convenience, I have attached a pdf with the instructions (2020909 anshinya.pdf, about 468 KB). The URL for the pdf is:
