Tax implications for leaving Japan?

Planning to leave my job soon, but the timing means I may still be in Japan for at least the first few weeks of 2026 even though I will stop working (and collecting a paycheck) in November or December.

What are the tax implications if I leave my job in Japan by the end of the year but stay here a few weeks into the new year?

Will I owe taxes for 2026 if I am in Japan but not earning a paycheck?
