Japan Part-Time Job Income Calculator

Notes

This tool uses regional minimum wages as a conservative estimate. It does not represent every actual job offer. Late night generally means 22:00 to 5:00. In Japan, a statutory holiday is one day per week, not the two days off per week that many people may imagine. Which day counts as the statutory holiday depends on the company. The minimum hourly multiplier for statutory holiday work is 1.35x, and 1.6x if it is also late-night work. Because statutory holidays in Japan can be arranged flexibly and depend on the actual contract, this tool does not calculate that scenario. International students are generally limited to 28 hours per week under permission to engage in activity other than that permitted by their status. During school breaks, a higher limit may apply when the conditions are met. Actual working hours must still follow your residence status, school documents, employer arrangements, and Japanese immigration rules. It is also worth noting that even with school documentation, many companies do not accept international students working 40 hours per week. Some students therefore work two part-time jobs during summer vacation. Based on what Donggui Xishi has seen, working a full 28 hours per week is already quite demanding. Please pace yourself and keep your studies as the priority.
