What to compare across Japan proxy sites
The useful comparison is not simply which proxy advertises the lowest headline fee. Compare marketplace coverage, whether the original Japanese listing remains visible, payment charges, storage rules, consolidation options, auction controls, shipping methods and the way estimates are separated from settled costs.
Match the proxy site to the marketplace you actually use
Mercari Japan, Yahoo! Auctions, Rakuma, retail stores and specialist hobby shops create different buying workflows. A strong Japan proxy site should preserve those differences instead of flattening every source into the same generic checkout.
Compare total landed cost, not one service-fee number
Item price, Japanese domestic shipping, proxy or payment charges, warehouse services, international freight and destination import costs can all affect the final amount. The cheapest advertised service can be more expensive for a particular basket if another cost layer is higher.
Check warehouse and consolidation rules before ordering
For multi-store shopping, storage time, arrival tracking, consolidation eligibility, repacking choices and parcel handling can matter as much as the purchase fee. These rules become especially important when buying several small collectibles or combining fixed-price purchases with auction wins.
Use marketplace-specific proxy guides for the final decision
After comparing Japan proxy sites at a high level, review the service in the context of the marketplace you plan to use. Mercari seller evidence, Yahoo auction bidding and retail-store inventory each need different checks before purchase.
