Did you know your employer also pays tax on your salary? It costs the employer 316,422 円 to pay you 31,391,793 円. In other words, every time you spend 10 円 of your hard-earned money, 4.60 円 goes to the government.
Real tax rate

So, with you and the employer both paying tax, what used to be a 45% tax rate now rises to 45.6%, meaning your real tax rate is actually 0.6% higher than what it seemed at first.
Summary
If you make 376,701,516 円 a year living in Japan, you will be taxed 169,619,070 円. That means that your net pay will be 207,082,446 円 per year, or 17,256,871 円 per month. Your average tax rate is 45.0% and your marginal tax rate is 46.1%. This marginal tax rate means that your immediate additional income will be taxed at this rate. For instance, an increase of 100 円 in your salary will be taxed 46.11 円, hence, your net pay will only increase by 53.89 円.
