People in Japan often hear that year-end adjustment means most employees are 'done' for tax purposes and then assume their side income can only matter if it becomes huge. Please explain why the NTA still draws lines around who must file, why the well-known 200,000 yen idea is not a general permission slip, and why refund claims can reopen the logic anyway.
