A man in Japan who earns 30 million yen (US$203,000) a year from rent and investments insists on continuing to work as a janitor to stay healthy and active.
Koichi Matsubara, 56, cleans public areas and carries out basic maintenance in a block of flats in Tokyo, according to the Japanese media outlet The Gold Online.
Matsubara reportedly works a four-hour shift three days a week.
The janitor job gives him a monthly income of 100,000 yen (US$680), much lower than Tokyo’s average salary of 350,000 yen (US$2,400).
Despite his modest job, Matsubara may be one of the building’s wealthiest “invisible millionaires”.
