Year 1 tax shock
Health insurance and resident tax are based on PRIOR year income. If you earned ¥8M last year and quit, you still owe taxes on ¥8M in your first year of no income.
!
Key money is non-refundable
Reikin (key money) of 1-2 months rent is a gift to the landlord. You never get it back. Budget ¥100-300K that’s just gone.
Guarantor company required
Most landlords require a guarantor company (hoshounin). This costs 50-100% of one month’s rent upfront, plus annual renewal fees.
Furnishing from scratch
Apartments come completely empty. No fridge, no washing machine, no light fixtures, no curtains. Budget ¥150-350K for basics.
