Less than one year
Japan NTA guidance says many working holiday visitors staying less than one year are basically non-residents. Japan-source salary is generally withheld at 20.42% and the taxation is completed by withholding.

Estimate salary tax for Japan working holiday searches like “Japan working holiday tax refund,” “20.42% tax,” and “foreigner tax return.” The calculator separates the official under-one-year non-resident rule from a resident-assumption comparison.
How to read the estimate
Refund expectation
For that under-one-year salary case, NTA guidance says the non-resident cannot file a final tax return and cannot receive a refund of the salary withholding.
Resident assumption
The resident comparison uses salary-income deduction, basic deduction, and social-insurance input to show why actual tax residency facts matter.
