A Japanese man recently shocked the internet after announcing that he managed to save 132 million yen ($640,000) over the last two decades with the goal of retiring early from his stressful job.

The unnamed 45-year-old man took to social media to announce that he had finally achieved FIRE (Financial Independence, Retire Early) after dedicating the last twenty years and ten months to this goal. In the early 2000s, he managed to secure a stable but very demanding job where he was constantly required to work overtime, sometimes past midnight. He had a decent salary of around five million yen ($32,000) per year, so instead of quitting his job and looking for something less stressful, he decided to push through all the hardships and save as much money as possible so he could retire early. However, the level of frugality he endured throughout the last two decades left a lot of people wondering if his efforts were worth it.
