Chiba (千葉県)
For the third consecutive year, the oldest living person in Chiba Prefecture is a 113-year-old woman of  Kimitsu City whose name has not been disclosed. As you all probably know, she has already became ''the oldest person ever to have lived in Chiba Prefecture''.
Also, the oldest living man is also 109-year-old Mr. Eito Kowase (強瀬衛人), of Minamibōsō City, marking the third consecutive year he has held this distinction. (It seems he moved from Tateyama City to Minamibōsō City.)
In addition, there are one 112-year-old woman, one 111-year-old woman, three 110-year-old women, and four 109-year-old women living here.
