A TYPICAL SEARCH
“ヘッドホン”
Search Rakuten Japan for “ヘッドホン”. Crumb compares each detected product’s text with that search, including any stated model, material or product type. It hides clear mismatches and keeps plausible results when a detail is missing. The filter uses text; it cannot determine something shown only in a photo.
HOW IT WORKS ON RAKUTEN JAPAN
Three small steps.
Search Rakuten Japan as usual.
Open a supported search page in desktop Chrome and type what you want.
Clear the obvious mismatches.
Crumb checks detected product text as results load. Unchecked results stay visible.
Bring every result back.
Turn Crumb off using the page switch or extension popup. Hidden results return immediately.
Good to know
on Rakuten Japan.
Where it works.
Japanese product search results on search.rakuten.co.jp. Product links point to item.rakuten.co.jp. Desktop Chrome only. Other country storefronts, product pages, carts and checkout pages are not covered.
Sponsored results.
Relevance filtering uses product text. Localized advertising labels are not covered.
Cautious by design.
Borderline results stay visible, and so does anything Crumb hasn’t checked yet or couldn’t check. It would rather show one extra result than hide a good one.
