Shopping across Amazon JP, Rakuten, and Yahoo! Shopping means juggling three separate tabs, three different layouts, and three sets of prices for the same product. dealJP fixes that — one feed, the deepest discount surfaced automatically.
dealJP earns a small commission when you click through and make a purchase. This never influences which deals appear or how they are ranked — the price data comes straight from the marketplace APIs. See the full affiliate disclosure for details.
dealJP is an independent project — not a corporation, not a funded startup. It is designed, built, and maintained by a single developer who got tired of manually comparing prices. Feedback and suggestions are always welcome via the contact page.
