On 1 September 2023, an interview with Hisao Ikeda (池田久雄), the oldest living man in Yokohama, Kanagawa (and also the oldest man in Kanagawa prefecture) was released, on the occasion of the Great Kantō Earthquake having been 100 years ago on that date (1 September 1923). The interview seems to have been conducted in June 2023. Mr Hisao Ikeda was born on 2 November 1912.

In addition to Mrs Yagida, there are two 109-year-old women living in the city. This means that an anonymous woman born in December 1912 has entered limbo. As the document can take us back to January 2023, where we can see two 110-year-olds (Mrs Yagida + someone else), we know that this woman has made it to supercentenarian status. In February 2023, the number of 110-year-olds was back to one, so this second woman entered limbo in January 2023, aged 110.

EDIT: never mind, the above info about the 110-year-old anonymous woman was already known.

Toki, Gifu reports a 113-year-old woman as its oldest living citizen (as of 31 August 2023). This concerns Okagi Hayashi (林おかぎ), who will have turned 114 two days later (born 2 September 1909). Mrs Hayashi is both LQ- and GRG-validated, and is the oldest living person in Gifu prefecture.

Here is the PDF file, in case the webpage disappears. On the first page of this thread, the correct names of the people have been rendered.

This document mentions that Mrs Masa Matsumoto (松本まさ) of Yokohama, Kanagawa, aged 113, born on 29 November 1909, both LQ- and GRG-validated, will be visited by the mayor of the city on 13 September 2023. She is the oldest living person in the prefecture.

This means that a woman from Tabuse, born in late 1911, has entered limbo, as well as a woman born in 1911 or 1912, residing in Shimonoseki.
