The world's oldest person has died nearly a month after celebrating her 117th birthday.

Misao Okawa.

Her nursing home says Misao Okawa died of heart failure today.

Okawa, born in Osaka on March 5, 1898, was recognized as the world's oldest person by Guinness World Records in 2013.

Her Osaka nursing home says she lost her appetite about 10 days ago. She stopped breathing as her grandson and nursing home officials attended.

Okawa, the daughter of a kimono maker, said at a birthday celebration last month that her life seemed rather short.
