TrustpilotMercari is two separate marketplaces: Mercari US at mercari.com and Mercari Japan at jp.mercari.com, each with its own listings, currency and rules. Resellers use it to price inventory from what similar items actually sold for, and to run their selling accounts day after day. Both jobs go better with the right proxy, and the seller side matters most: Mercari pays close attention to how an account signs in.
How Mercari localises, limits and checks traffic, and what that means for your setup.
Mercari US and Mercari Japan do not share accounts, listings or currency. A Mercari US account is for the US market; for Mercari Japan research you need a Japanese exit IP and Japanese-language queries to see what local buyers see.
Asking prices on active listings are often far above what items sell for. Filter searches to sold items and record the sale price and date, not the list price, when you value inventory.
Mercari looks at sign-in location, device and payment details together. An account that hops between IPs or shares an IP with unrelated accounts is more likely to be asked to verify or be restricted.
Offers, likes and buyer messages run through the app's own flows. Keep them manual or at a human pace; automating them is where seller accounts most often run into Mercari's rules.
Our recommendation for Mercari, and when the second option is the better choice.
A Mercari seller account lives on its listings, offers and payouts, so you want it to sign in from the same place every day. A static ISP proxy gives each account one fixed US address on a home-ISP range, with unlimited bandwidth for photo uploads and relisting.
Dedicated static IPs registered to US and Canadian ISPs. The address stays the same for as long as you hold it, with unlimited bandwidth and HTTP(S) or SOCKS5 access.
For research across many search and item pages, such as checking sold prices for a product line, rotating residential proxies spread the requests across many IPs. Target the United States for Mercari US or Japan for Mercari Japan, where prices are in yen and listings are in Japanese.
Residential IPs in 190+ countries with country, state and city targeting. Rotate on every request or hold a sticky session for up to 90 minutes; GB never expire.
Every CleanProxies proxy connects over HTTP(S) with the credentials in your dashboard; ISP and ISP subnet proxies also run SOCKS5. Test them with the free proxy checker and convert lists with the proxy list formatter.
Buy one static ISP proxy for each Mercari US account you run and note which IP belongs to which account.
Load that IP into its own browser profile, or route the phone or emulator that runs the account through it, and never sign in to that account any other way.
Create a rotating residential plan targeted to the United States (or Japan for jp.mercari.com) and use it only for logged-out searches.
Store each sold price with the item condition, date and marketplace, so a US sale and a Japanese sale are never mixed in the same average.
Follow Mercari's Terms of Service and prohibited-conduct rules: collect only public listing data at a modest rate, keep your accounts within Mercari's rules on multiple accounts, and do not use proxies to return after a suspension, automate offers or messages, or manipulate listings. CleanProxies customers must follow our Terms of Service and the laws that apply to them; this page is general guidance, not legal advice.
