Best depends on the transaction you are actually making
A proxy that is excellent for one Mercari purchase may not be the best choice for a Yahoo auction, a ten-store collector haul or a fragile camera. Start with required marketplace access and operational reliability, then compare cost on the same basket.
Score six operational questions
- Can it buy or bid on the exact Japanese source?
- Does it preserve seller, variant and condition evidence?
- How is the service fee charged for this basket?
- What storage, consolidation, photo or inspection options are relevant?
- Can the warehouse pack this category appropriately?
- Which eligible carriers can quote the final parcel to your US destination?
Use a small trial order before a complex haul
A controlled first order exposes the full path: source capture, authorization, Japan-side purchase, warehouse receipt, any optional handling, packing and final carrier quote. That evidence is more useful than ranking services from fee banners alone.
Where to check current fee data
For a current side-by-side fee snapshot, use the dedicated Japan proxy service comparison . It keeps the four primary fee sources in one place so category pages do not repeat a stale table.
Example: the winner can change by basket
For one ¥8,000 store item, a fixed per-order purchase fee can be competitive. For eight separate Mercari sellers, per-item or per-request charges and storage become more visible. For a large figure, the proxy fee may be dwarfed by packing and dimensional freight. The “best” service can therefore change even for the same buyer across three months of different orders.
Keep a service-change log
When you test proxies, record the review date, official fee link, source basket, payment method, warehouse options and final packed quote. This prevents a comparison from becoming stale folklore and gives you a reproducible reason to stay with or switch services later.
