Sū Yamada (Japanese: 山田スウ) was a Japanese supercentenarian whose age has been validated by LongeviQuest.


Yamada was born in Ōita Prefecture, Japan, on 16 January 1883. At the age of 19, she married Tokunosuke, a fisherman who lived nearby. The couple had five sons and three daughters.

Around the age of 107, her legs began to weaken, causing her to spend more time in bed, though she remained self-sufficient in her daily activities. She possessed a methodical personality, maintaining impeccable tidiness, and even at 107, it noted how she had a lot of black hair. However, shortly before her 111th birthday, her health deteriorated, leading to her hospitalization. During the time she resided with her daughter-in-law and grandchildren, she maintained a structured daily routine. She would rise at 6:00 in the morning and retire around 9:00 at night. Her diet consisted of three meals a day, with a preference for meat and fish. One of her hobbies was watching sumo wrestling.

Yamada passed away in the village of Yonōzu (now part of the city of Saiki), Ōita Prefecture, Japan, at 11:03 am on 26 March 1994, at the age of 111 years, 69 days. She was survived by around 90 descendants, including her great-great-grandchildren.
