Did you know your employer also pays tax on your salary? It costs the employer 155,372 円 to pay you 4,550,000 円. In other words, every time you spend 10 円 of your hard-earned money, 4.21 円 goes to the government.
Real tax rate
40.7%
So, with you and the employer both paying tax, what used to be a 38.7% tax rate now rises to 40.7%, meaning your real tax rate is actually 2% higher than what it seemed at first.
Summary
If you make 54,600,000 円 a year living in Japan, you will be taxed 21,107,192 円. That means that your net pay will be 33,492,808 円 per year, or 2,791,067 円 per month. Your average tax rate is 38.7% 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 46.10 円, hence, your net pay will only increase by 53.90 円.
Bonus Example
A 1,000 円 bonus will generate an extra 539 円 of net incomes. A 5,000 円 bonus will generate an extra 2,695 円 of net incomes.
