Limbo is a term used for supercentenarians who have "disappeared", don't have a confirmed death date, or don't have any reports for a long time, usually over one year. Most of these cases turn out to be deceased. Many, but not all, of these cases are from Japan as the government there tends to report supercentenarians who are living on Respect for the Aged Day (the third Monday of every September) but only publish follow-up death reports in certain cases (for example, the death of Japan's oldest living woman or man or the oldest living woman or man in the prefecture).
