Kane Tanaka, the oldest person in the Guinness world records, turned 117 in a rest home in Fukuoka, southern Japan, last January 2. In the previous year, she was listed as the oldest living person in the world. Tanaka had four children and an adopted child. She and her husband Hideo worked in a shop selling shiruko and udon noodles. She retired from work at the age of 63, while her husband and son died in the war.

Tanaka’s age is a sign of the fast-growing population of Japan. Based on Japan’s Ministry of Health, Labour and Welfare, the number of Japanese people over the age of 90 increased to two million for the first time in 2017 and expanded from 1.02 million to 2.06 million in 2004. The Japanese population over 65 years of age increased by 35.14 million or 27.7% in 2017, while the number of births decreased by one million for the first time in 2016. According to the report, young Japanese people are focusing on their jobs and avoiding marriage. On the other hand, the elderly have been living longer than before.
