Medical Expenses Deduction
The deduction is applied to medical expenses that exceed either ¥100,000 or 5% of income, whichever is lower.
An official spreadsheet for tallying the medical expenses can be downloaded from the NTA by selecting 医療費集計フォーム from the tax return page (Japanese). This spreadsheet can be uploaded to eTax to automatically calculate the deduction and generate the relevant documents.
