Umeno Sumiyama and Koume Kodama have broken the record set by late Japanese twin sisters Kin Narita and Gin Kanie.
Umeno and Koume, both described as sociable people, were born on 5 November 1913 on Shodoshima island.
The announcement was made on Monday to coincide with Respect for the Aged Day - a national holiday in Japan.
Due to the current situation with Covid-19, and as a precaution, the sisters - who live in different parts of Japan - were sent their official certificates to be presented by staff at their separate care homes.
