The average annual income of chefs working in Japan is 4,300,000 JPY before taxes (Its about 39,000USD).
Chefs at high-end sushi restaurants or Japanese restaurants may get paid more than 6 to 10 million JPY (55,000 to 91,000USD). Everyone wants to improve their situation when changing jobs, but it’s not easy to fully grasp the cost of living overseas.
For this reason, and to avoid problems after hiring, please explain as clearly as possible to the new recruit details such as the salary before and after taxes, local living expenses, health insurance etc. Honestly speaking, some people are ok with a lower salary if it turns out that they can save up more than when working in Japan.
