LINE Chat Commerce vs a Standalone Storefront: Where Should Japanese Shoppers Actually Buy?

Every comparison we have published so far about where to sell in Japan — Rakuten against Amazon, Yahoo! Shopping against Rakuten, a Shopify store against all three — is a comparison between search-driven storefronts. A shopper types a query or browses a marketplace category, lands on a listing, and buys. LINE breaks that pattern entirely, and most brands selling into Japan already have a foothold on it without having asked whether it is a sales channel: a LINE Official Account run for customer service, order-status messages or promotional broadcasts. The question this article answers is whether that foothold is worth turning into a place people actually buy — and what that costs, in money and in platform risk, against building a standalone store instead.

What LINE Chat Commerce Actually Means

"LINE chat commerce" is not a LINE product. It is a category of third-party apps that connect to a LINE Official Account and add a browsable catalogue and a checkout inside the chat thread. Two of them — Lineup and CHATY — we could confirm are currently active, with current published pricing. A third name that circulates in secondary write-ups about this category, BuyChat, we could not confirm is still operating as of this research round, so it is left out of the comparison below rather than listed as a live third option (see the cost section for what we tried). A shopper who is already a "friend" of your account taps a rich menu or a message, sees products without leaving LINE, and pays by card, PayPay or another supported method, sometimes in as few as two taps. The app is doing the work; LINE is providing the messaging surface and the audience relationship.

That distinction matters because of what LINE itself does not provide brands. As of August 2026, LINE for Business's own service pages, its published LINE Official Account pricing page, and its Product Guide PDF — the version we read is dated 8 June 2026 — describe no native storefront-building or checkout feature for merchants. There is a similarly named item that trips people up: a "Store & EC" bundle sold as part of LINE Notification Messages, a pay-as-you-go plan covering roughly 53 transactional message templates for things like shipment notices, reservation confirmations and payment reminders. It is a notification product for orders that already happened somewhere else, not a way to take an order. If you are searching for whether LINE itself sells you a shop, the honest answer is that it does not, and everything past this paragraph is about the apps that fill that gap.

LINE Has Already Shut Down Its Own Commerce and Payment Bets

Before weighing the third-party option, it is worth knowing what LINE has tried and abandoned directly, because it bears on how much you should lean on anything LINE runs itself rather than a partner app running on top of the platform. The most recent case closed while this article was being written. LINEショッピング (LINE Shopping), LINE's own shopping-search and price-comparison product, stopped accepting new orders on 16 February 2026, the service itself ended on 1 June 2026, and its customer support closes on 31 August 2026, according to LINE's own closure notice. LINEギフト (LINE Gift), a separate LINE-run product for sending gifts through the app, is unaffected and continues to operate — the two are not the same thing, and it is worth not conflating them if you searched your way here.

LINE Shopping is not an isolated data point. LINE Pay, LINE's own digital-wallet and payment product for the Japan market, was shut down on 30 April 2025, per LINE Yahoo's own notice to Official Account holders — which is also, not coincidentally, why none of the third-party chat-commerce apps we checked list LINE Pay as a payment option; PayPay, credit cards and Paidy have taken its place. Further back, LINE ran an earlier commerce push under the LINE FLASH SALE brand, launched in 2015, which was discontinued within roughly a year as LINE pulled back from consumer-to-consumer commerce more broadly — we did not independently re-confirm every date in that older episode this round, so read it as directional pattern rather than a precisely dated event the way the 2026 and 2025 cases are. The pattern across all three, precisely dated or not, is the same: LINE has repeatedly built and then walked away from doing commerce and payments itself. The layer that has proven durable is the one running on top of the Official Account via a partner app, because Official Accounts are the core product LINE has kept investing in rather than a side bet.

The Real Choice: A Third-Party Chat Shop vs a Standalone Storefront

With LINE's own role clarified, the actual decision is between two ways to sell that both work today: layering a third-party checkout onto an Official Account you already run, or building a standalone storefront — the Shopify-style model we cover in our Shopify Japan localization guide — that stands on its own domain and earns its own traffic. They are not mutually exclusive over time, but most brands are choosing where to put the next unit of build effort, not choosing a religion, so the comparison is worth making on the dimensions that actually move revenue: how you get someone to look, how they pay once they are looking, and what kind of buying pattern rewards each approach.

Acquisition Cost: Reusing Friends vs Cold-Starting Search and Ads

A standalone Japan storefront opens with zero visitors. Every one has to be earned — through Japanese-language SEO, paid search, paid social, or influencer work — in a market where none of that is a plug-and-play import from a home-market playbook, a point our Shopify comparisons have made about DTC launches generally. A LINE-embedded shop starts from a different position: if you already run an Official Account with a real friend list built from customer service, receipts or campaign sign-ups, that list is your day-one distribution, and the marginal cost of putting a product in front of it is close to zero. LINE's own scale supports why that list can matter — LY Corporation reported more than 100 million monthly active users in Japan as of December 2025 in a 29 January 2026 release — but the number that actually matters for your decision is not LINE's total reach, it is the size and quality of your own friend list. An account with a few hundred stale friends gains almost nothing from adding a checkout; the acquisition-cost advantage belongs entirely to accounts that have already done the work of building a real relationship.

Conversion Path: In-Chat Purchase vs Checkout Redirect

The two channels also differ in how many steps stand between "interested" and "paid." A chat-commerce app keeps the shopper inside the thread they are already in — browse, select, pay, done, often in a couple of taps, with no domain switch and no separate login to abandon at. A standalone storefront, by contrast, routes a shopper through a landing page, a product page, a cart and a checkout, each a point where they can leave — the same funnel every marketplace and DTC store runs, just without a chat interface's shortened path. That shortened path is chat commerce's genuine structural advantage for a shopper who already trusts the sender enough to be a "friend." It is a weaker advantage for a shopper being acquired cold, because a chat thread is a poor surface for the comparison shopping, filtering and browsing that a first-time, undecided buyer usually wants — which is the underlying reason chat commerce tends to convert existing relationships better than it creates new ones.

Where This Actually Fits — and Where It Does Not

Put the two factors together and the shape of the decision becomes clearer than "LINE is popular, so sell on LINE." Chat commerce tends to fit repeat-purchase, service-adjacent businesses: consumables and replenishment products, appointment-linked retail, or brands whose Official Account already functions as a customer-service channel where a purchase is a natural extension of an existing conversation. It tends to fit poorly for one-time acquisition pushes, wide catalogues that need filtering and comparison, and any launch strategy that depends on cold traffic finding you — which is precisely the job a standalone store, a marketplace listing, or a properly built Japan EC operation across Rakuten, Amazon Japan and Yahoo! Shopping is built to do. Treating a LINE-embedded shop as a replacement for demand generation, rather than as a monetization layer on demand you already generated, is the most common way brands over-invest in it.

What the Third-Party Tools Actually Cost

Secondary write-ups about LINE chat commerce tools tend to repeat a "zero setup, zero monthly fee, pay only when you sell" pitch. We priced the two tools with public, current pricing pages ourselves rather than trust that framing, and it is dated for at least one of them.

Lineup (lineup.market) currently lists a Standard plan at ¥0 setup and ¥3,000 a month including tax, with the first 30 days free and no minimum contract term. On top of the monthly fee, Lineup takes a 1.5% platform fee on order value, and payment processing runs a further 3.5–3.8% depending on method — 3.8% for PayPay, 3.6% for credit card, 3.5% for Paidy in what we read. A higher Pro tier is quote-only. On a hypothetical ¥100,000 month of card sales, that works out to roughly ¥8,100 in combined platform, transaction and processing costs against the fixed ¥3,000 — not free, and not commission-only.

CHATY (chaty.shop) is the clearer case of the "free until you sell" pitch going stale. Shops that registered before 22 April 2025 keep the older model: no monthly fee, a flat 5% commission plus ¥100 per transaction, restricted to LINE's in-app payment and subject to approval. Shops opened from that date onward are on a different structure entirely — a monthly fee that scales with LINE friend count, starting at ¥3,300 a month for up to 500 friends and rising through tiers to ¥110,000 for 50,001–100,000 friends and ¥220,000 for 100,001–300,000 friends, with a custom quote above that. On top of the monthly fee, the standard variant adds a 3% plus ¥100 per-transaction commission on card payments; a fee-only variant drops the transaction commission but gives up LINE's in-app payment method. Any brand large enough to have tens of thousands of LINE friends is, under the current model, paying a five- or six-figure monthly yen fee before a single sale, which is the opposite of the commission-only story still circulating in secondary coverage.

A third name, BuyChat, shows up in secondary write-ups about this category alongside Lineup and CHATY. We are not including it in the comparison above: its site (buychat.shop) did not resolve during our research session, no secondary source carried current pricing, and — unlike Lineup and CHATY, where recent activity and current pricing pages are easy to confirm — we could not establish that it is still operating as of this round. Read its absence here as unverified, not as a verdict that it is defunct; check the vendor's own current status directly before including it in any comparison.

Lineup and CHATY both sit on top of a LINE Official Account, which carries its own separate cost once your friend count or message volume outgrows the free tier. LINE's own published plans (lycbiz.com, checked August 2026) are Communication at ¥0 a month for 200 free messages, Light at ¥5,000 a month excluding tax for 5,000 messages, and Standard at ¥15,000 a month excluding tax for 30,000 messages, with tiered per-message pricing beyond the Standard plan's quota. LINE Yahoo has separately announced that the pricing for messages beyond quota will be revised from 1 October 2026 — we confirmed the revision itself on LINE Yahoo's own pricing page, though we relied on a vendor's secondary summary for the specific post-revision per-message rates, so treat those exact new numbers as reported rather than independently confirmed by us. None of this changes what the embedded-shop apps charge on top; it is the cost floor underneath them.

How to Decide, in Order

1. Look at your actual friend list, not LINE's user base. A large, engaged Official Account friend list is the entire case for chat commerce's acquisition-cost advantage. Without one, you are paying a vendor's fees to rebuild a cold-start problem a standalone store already has for free.
2. Match the channel to your purchase pattern. Replenishment, appointment-linked or service-adjacent buying rewards an in-chat checkout. Comparison-heavy, wide-catalogue or one-time-acquisition selling does not.
3. Price the real fee stack, not the vendor pitch. Monthly platform fees, per-transaction commissions and payment-processing fees stack differently across Lineup and CHATY, and CHATY's own pricing has already moved once, in April 2025. Re-check current numbers before committing rather than trust a blog post's summary, ours included.
4. Treat chat commerce as a layer, not a foundation. Use it to monetize a relationship you already built through customer service or campaigns; use search, marketplaces and paid acquisition to build the relationship in the first place.
5. Keep your data portable. Given LINE's own record with Shopping and Pay, plan around exportable product and customer data rather than assume any embedded tool's access terms are permanent.

Where we fit is deliberately narrow. We run Japanese storefronts and marketplace operations for overseas brands — the listings, the Japanese-language customer contact, the campaign calendar, the platform work — across Rakuten, Amazon Japan, Yahoo! Shopping and Shopify. We are not a LINE tool vendor, we do not resell or receive referral fees from Lineup, CHATY or any similar app, and we do not broker payments. What we do is help a brand sequence which Japan channel to build next based on where its actual customers and acquisition spend already sit. If you want that mapped against your own account and catalogue, tell us what you sell and what your LINE presence already looks like. Scope and pricing are quoted against the work rather than published as a rate card.
