The world’s oldest person, Kama Chinen, of Okinawa, Japan, died on Sunday just a week short of her 115th birthday, Guinness World Records reports.

Chinen was the world’s oldest living person for almost eight months following the September 11, 2009, death of American Gertrude Baines, according to a Guinness statement. It said it is researching who is now the world’s oldest living person.

The all-time record for longevity is France’s Jean Louise Calment, who died in August 1997 after living 122 years, 164 days, Guinness said.
