# 일본 면세 환급 계산기 (Japan Tax-Free Refund Calculator, Korean)

> Free Korean-language browser tool that explains Japan's new tax-free refund system starting 1 November 2026 (switch from instant tax-free purchase to post-purchase customs-verified refund) and lets visitors estimate their expected consumption-tax refund. Built for Korean tourists visiting Japan, who are the largest inbound nationality group (about 9.46 million visitors in 2025).

## Key facts
- From 1 November 2026, Japan changes its foreign-tourist tax exemption from "instant tax-free pricing at the register" to a "buy tax-included, then get verified and refunded at customs on departure" system.
- Minimum purchase to qualify: 5,000 yen or more at the same store on the same day (general goods and consumables combined; the old 500,000 yen consumables cap is expected to be abolished, subject to final rules).
- Standard consumption tax rate is 10%; a reduced 8% rate applies to food and non-alcoholic beverages.
- Refund estimate formula used by the calculator: refund = purchase amount × tax rate ÷ (100 + tax rate). This is an approximation; actual refunds may be reduced by service fees charged by refund operators.
- Missing the customs verification step at departure can mean forfeiting the refund, so travellers should arrive at the airport with extra time.
- All calculation runs client-side in the browser; nothing entered is uploaded or stored.
- This is an independent, unofficial guide, not affiliated with the Japanese government or customs authority. Details may change before the system takes effect; always confirm with the store or customs on the day.
