Will this product make money in Japan?

Start with the product and its cost. Optional facts improve confidence.

Try an example

Official tax and FX rules are combined with clearly labeled estimates. This demo does not store the submitted product or financial values.

Your decision appears here

See the recommendation first, then selling price, total cost, profit, margin, break-even price, recommended minimum, and confidence.

Simple first, precise when needed

One answer, with every estimate visible.

The calculation combines Japan Customs tariff and valuation data, National Tax Agency rates, official Customs FX rates, and official channel fee pages. Shipping and logistics defaults stay labeled until you replace them.

Standalone
Product name and cost are enough for a provisional result.
Sellability compatible
Reuse category, origin, HS code, status, confidence, and sources.
Deterministic
Money is calculated by code, not generated by an LLM.

Replace the spreadsheet chain with one request.

Calculate first, then add actual freight, fee, and tariff inputs whenever you need more confidence.
