Yasuko Tamaki, a Japanese professional from Osaka, has spent more than 65 years in the same role at the same company. Joined Sunco Industries Co., Ltd. in 1956 at the age of 26 and continued to work into her 90s. Her daily routine ran from 5:30 a.m. to 5:30 p.m., marking a career of rare dedication.
In November 2020, Guinness World Records recognized Tamaki as the world’s oldest office manager. Born on May 15, 1930, she was 90 years and 174 days old at the time of receiving her degree. Reports say she is still actively working in 2024, and a YouTube channel later claimed she was working in 2025 at the age of 95.
During her career, Tamaki has seen Sunco Industries grow from a small company with about 20 employees to a company with more than 430 employees. She worked in the Public Affairs Department, where she handled accounting, administration, and internal communications. She was promoted to department head at the age of forty.
Tamaki started learning computers at the age of 67 and mastered it by the age of 70. I continued to obtain certifications and learn new tools. At the age of 86, she was still pursuing her formal studies, and by the age of 90, she was using several social media platforms.

She reportedly wakes up at 5.30 a.m., practices yoga, and recites Buddhist sutras before walking, bus or metro to work. She enjoys reading, card games, mahjong, and taking the Japanese Kanji proficiency test to keep her mind sharp.
Upon receiving the award, Tamaki said she was deeply touched and believed that small efforts add up over time. She said her goal is to be useful to others and make her colleagues happy.
