Convert a price between including and excluding Japanese consumption tax - 10% standard or 8% reduced rate, no upload.
No. Everything runs in your browser - your file never leaves your device. How this is verifiable
Shohizei (消費税) is Japan's consumption tax, comparable to VAT. Since October 2019, a standard rate of 10 percent applies, alongside a reduced rate of 8 percent for most food and drink (excluding alcohol and eating in at a restaurant) and certain newspaper subscriptions. This tool converts an entered price in both directions: from tax-exclusive to tax-inclusive, or the reverse.
Enter your price, choose whether it already includes tax, and the matching rate - the tool instantly shows the tax-inclusive price, the tax-exclusive price and the pure tax amount. When converting FROM a tax-inclusive price, the net amount is rounded down to the whole yen, matching standard Japanese retail practice.

Does not check whether a specific product actually qualifies for the reduced rate (e.g. the alcohol/dining-in exceptions) - that judgement is yours to make. Not a substitute for tax advice, Japan only.
