According to Oddity Central, the choice to live an extreme frugal lifestyle was driven by his desire for early retirement. He feels that the job he is currently doing is full of pressure. The 45-year-old man, who did not disclose his name, announced on social media that he has finally reached the FIRE (Financial Independence, Retire Early) stage or is financially independent and ready for early retirement after dedicating his life to frugal living for the past two decades.

"In the early 2000s, he managed to get a job but was constantly asked to work overtime, sometimes until after midnight. He had a decent salary of around five million yen per year. However, instead of quitting his job, he decided to face all the difficulties and save as much as possible to achieve his ambition of early retirement."

"In his effort to save 100 million yen as quickly as possible, he completely changed his lifestyle. He left his rented apartment and chose to live in a simple company dormitory. For this, he only paid 30,000 yen per month. He also did not buy the necessary equipment and furniture. Instead, he looked for them by scavenging or utilizing items discarded by others. "

"However, there are days when his dinner consists only of simple energy drinks. This man also never uses air conditioning in the summer and only uses a blanket and cloth to keep warm in the winter."
