The twins, who live in separate care homes, were presented with their certificates via mail due to the COVID-19 pandemic.
The record was previously held by fellow Japan residents Kin Narita and Gin Kanie. Kin Narita died at age 107 years,175 days in 2000.
Care home workers said Sumiyama became emotional and was in tears when she was presented with the certificate. Kodama, whose memory has been deteriorating, was unable to comprehend the significance of the certificate, Guinness said.
