A Personal Financial Simulation for Japanese Hospital-Employed Physicians.

Introduction Physicians in Japan are generally high earners, but many face challenges in accumulating sufficient financial assets due to a lack of financial education. This study aimed to examine the savings and investment strategies necessary for hospital-employed physicians in Japan to reach affluence. Materials and methods A financial simulation was conducted using average income data for hospital-employed physicians, considering different saving rates (5-40%) and annual investment returns (1-10%). The study also assessed the tax-saving effect of the Nippon Individual Savings Account (NISA). Results Hospital-employed physicians can accumulate 100 million Japanese yen in financial assets by saving at least 10% of their income with an annual return of 4% over 40 years. The use of NISA can further reduce taxes, increasing overall returns. Conclusions By adopting appropriate savings and investment strategies, including tax-advantaged options like NISA, hospital-employed physicians in Japan can build sufficient wealth for financial security.
