About
I built Japan Refactor to help foreign engineers easily navigate Japan’s complex tax, pension, and visa systems without the headaches.
Living and working in Japan as a tech professional comes with unique administrative challenges. I created this free suite of precision calculation tools to give immediate clarity on your finances and career milestones in Japan:
🚀 What’s inside:
Take-Home Pay (Salary) Calculator: Instantly estimate your net income after income tax, resident tax, and social insurance deductions.
Health Insurance Calculator: Simulate 2026 NHI premiums and resident tax time-lags to assess your readiness for transitioning to freelancing.
Pension Lump-Sum Refund Calculator: Calculate exact refundable amounts if you decide to leave Japan.
HSP Visa Points Calculator: Track your current score toward Japan's Highly Skilled Professional Visa.
Built for the builder and expat community in Japan—100% free and ready to use! Would love to hear your feedback or suggestions for new features.
