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.
