Switching or Exiting a Japan EC Agency: What You Actually Keep

The decision to change agencies is usually easy. Sales are flat, reporting is thin, your questions take four days to answer in a language you cannot audit. What is not easy is discovering — three weeks into the switch — that the store account is in the agency’s name, that your Japanese product pages are their copyright, and that your contract needed two months of written notice you did not give.

This article is about that second part, written from the position brands are actually in when they search for it: already signed, already live, wondering how much of the last eighteen months is portable. If you have not signed yet, read it as a list of things to fix before you do. Our guide to how to choose a Japan EC agency covers the selection side; this is the exit side of the same relationship. Nothing here is legal advice — the Japanese rules below are summarised with sources, but your position depends on your contract, and the clauses that matter at exit are the ones worth paying a Japanese lawyer to read.

Settle Ownership Before You Serve Notice

The most expensive mistake in a switch is doing things in the wrong order — telling the incumbent you are leaving before confirming what you can take. Once notice is served, cooperation becomes voluntary, and anything you have not already secured is something you are asking a soon-to-be-former supplier for as a favour. So the sequence is: establish ownership, recover access, document the handover requirements, then serve notice. Work through the four questions below on paper before you write a single email about leaving.

Question 1: Whose Name Is the Store In?

This determines whether you are doing a handover or a rebuild, and the answer is in your platform contract rather than your agency agreement.

Rakuten Ichiba

A Rakuten Ichiba store is opened under a merchant — a specific legal entity or sole proprietor — and that merchant is the party to the store contract. Rakuten does not let you quietly move a store to a different company: its business-succession service states that a store contract may be changed to another legal entity only where Rakuten has consented in advance, and routes genuine cases such as business transfers, mergers, and company splits through a formal contract-holder change application. If your agency opened your store under its own corporate name, that is not a formality standing between you and your store. That is someone else’s store selling your products.

Where the merchant is your own company, the picture is much better. Rakuten manages RMS access through R-Login, with roles split across a responsible person, administrators, and staff, and permissions set per service — so your agency should be working through staff-level accounts issued from your master account, which you can revoke without involving them. If you cannot log in to your own master account today, fix that before any conversation about leaving.

Amazon Japan

Amazon pushes the same way. The Business Solutions Agreement every seller accepts restricts you from assigning the agreement without Amazon’s prior written consent, so a seller account is not casually handed from an agency to a brand. Seller Central’s user-permissions system is built for the correct arrangement instead: the account owner invites users, grants access section by section, and removes it at will. If your agency logs in with your credentials rather than their own permissioned user, you have no access log, no selective revocation, and a security problem that outlives the relationship.

The variant that traps people: selling under someone else’s store

A common shortcut for skipping the entity and application work is to sell through a Japanese partner’s existing Rakuten store, or the agency’s own store, with your products listed inside their shop. It gets you live quickly. It also means the store, the reviews, the customers, and the search history are theirs, and there is no exit that preserves any of it because there is nothing to transfer. Neither platform publishes a rule settling whether this is permitted, so treat it as a commercial risk you are accepting rather than a compliance question with a clean answer. If avoiding a Japanese entity is what drove you here, answer that question directly first — we work through it in do you need a Japan entity to sell ecommerce.

Question 2: What Survives the Switch, and What Resets

The commercial value of an established Japanese store is mostly in things you cannot buy back: review count, review score, and the sales history that feeds ranking. If the account stays the same and only the operator changes, none of it moves — reviews and history attach to the account, so the switch is invisible to the platform and to your customers. That is the whole reason account ownership is the first question.

If you have to open a new store, the picture is brutal. Rakuten shop reviews attach to the store; Amazon seller feedback attaches to the seller account; Amazon product reviews attach to the ASIN, staying with the listing rather than following you as a seller. Neither platform offers a general route to migrate reviews between separate stores — Rakuten’s only documented migration mechanism is a narrow same-store product-page case. Assume a new store starts at zero reviews, zero history, and no ranking, and price the switch accordingly.

Question 3: Do You Own the Japanese Content You Paid For?

Foreign brands routinely assume commissioned work is theirs because they paid for it. Japanese copyright law does not work that way.

The work-for-hire provision in Article 15 of the Copyright Act covers works created by a person engaged in the business of the organisation — an employment-style relationship judged on real supervision, not a label. An external agency writing your Japanese product copy or shooting your images generally does not fall inside it, so copyright starts with the creator. Payment and a detailed brief do not change that on their own.

Transfer therefore has to be written down, and written down precisely. Article 61(2) presumes that the rights of adaptation and derivative-work use are not included in an assignment unless specifically named — exactly the rights you need in order to edit and reuse copy and imagery on another platform later. A clause saying “all copyrights transfer to the client” without naming them may leave you unable to modify your own product pages. Moral rights are inalienable under Article 59, so Japanese contracts customarily add a covenant not to exercise them, which courts assess case by case rather than treating as automatically valid.

The consequence at exit: if your contract is silent, the outgoing agency may hold copyright in the Japanese copy and photography currently running on your store — sometimes released without argument, sometimes used as leverage at the moment you have least. Check the clause now, and if it is missing, fix it at the next renewal rather than during termination.

Question 4: Ads, Data, and Customer Information

Advertising. On Rakuten, RPP and the rest of the promotion tooling live inside RMS, so campaigns and reports sit with the store account and stay put through an operator change; performance reports export from RMS. On Amazon, the advertising console is entered with your seller credentials, and agencies typically obtain access through a manager-account relationship you can grant and withdraw. Export the history anyway, before notice: keyword-level performance over the last twelve months is the most useful artefact a new operator can inherit, and the easiest to lose in a bad-tempered exit.

Customer personal data. Where an agency handles your customers’ personal information, Japan’s Act on the Protection of Personal Information puts a supervision duty on you as the entrusting party under Article 25, which the Personal Information Protection Commission’s guidelines break into selecting an appropriate contractor, having a written entrustment contract, and staying informed about how the data is handled. Note what the law does not say: there is no explicit statutory rule requiring return or deletion when the contract ends — Article 22 sets only a duty to endeavour to erase data no longer needed. Return-and-certified-deletion at termination is contract practice, so it has to be in your agreement.

Trademark. Japan is first-to-file: Article 8 of the Trademark Act awards registration to the earliest applicant among competing applications for the same or similar marks on the same or similar goods, regardless of who used the mark first. If your Japanese trademark was filed by anyone other than you — including a helpful partner or agency — resolve that with a benrishi or lawyer now, not at exit.

The Exit Clause: Notice, Minimum Terms, and Termination Rights

There are two layers here, and brands routinely confuse them.

The first is your contract. Japanese EC operations contracts commonly specify a minimum term and a written notice period; agencies themselves publish minimum terms in the three-to-six-month range, and one month of written notice appears as a typical clause in Japanese contract templates and practitioner commentary. Those are conventions reported by vendors and practitioners, not official statistics and not a legal standard — your number is whatever your contract says. Read it, then count backwards from the date you want the new team live.

The second is the Civil Code. Article 651 allows either party to a mandate to terminate at any time. It is not a free pass: a party terminating at a time disadvantageous to the other, or terminating a mandate that also serves the mandatary’s interests, may owe damages unless there were unavoidable grounds, and Japanese courts have upheld termination of fixed-term arrangements while awarding compensation reflecting the remaining fee. Excessive penalty clauses can be challenged as contrary to public policy under Article 90 — but that is a dispute, not a plan.

The pragmatic reading: your notice clause governs, the Civil Code is the backstop if the relationship has genuinely broken down, and the cost of an early exit is a number to negotiate rather than a wall. If the fee structure rather than the performance is what is driving the exit, check whether a different Japan ecommerce pricing model fixes it before you incur switching costs at all.

Avoiding the Dark Period

The switch has a failure mode with nothing to do with contracts: the store going unattended. Japanese ecommerce is unforgiving about this — customer enquiries carry expected response times, Rakuten’s event calendar has entry deadlines that do not move, ad budgets keep spending against stale keywords, and marketplace stock-outs cost you ranking, not just orders.

Three rules keep the gap closed. Overlap where you can: a paid parallel window of two to four weeks is cheaper than any of the failure modes above. Never time a switch into a major sales event — the run-up to Rakuten’s large campaigns is the worst moment to have two teams half-attached to a store. And keep credentials continuous: issue the new operator their own permissioned accounts before revoking the old ones, so there is never a window in which nobody can log in. That continuity is what a remote Japan operations support arrangement is for, and it is the part of a switch most worth over-resourcing.

The Offboarding Checklist

Send this to the outgoing agency in writing, with a date against each line.

• Accounts. The merchant name on each platform contract, confirmed. Master-account credentials verified working by you, not described to you. Every user account the agency created, with confirmation of removal after handover.
• Platform data. Order and customer exports, product master export, and twelve months of sales reporting from each back office.
• Advertising. Campaign, keyword, and performance exports from RPP and Amazon Ads covering at least twelve months, plus current budgets and scheduled campaigns.
• Content. Source files — layered images, original photography, page HTML or templates — not just what is visible on the live store, plus written confirmation of the copyright position referencing your contract clause.
• Customer service. Open ticket list, Japanese response templates, and escalation history for anything unresolved.
• Operational calendar. Campaign entries already submitted, promotions scheduled beyond the termination date, and commitments made to the platform on your behalf.
• Third parties. Contacts and account status for logistics, photography, or translation vendors the agency engaged, and whether those contracts are in your name or theirs.
• Personal data. Written confirmation of deletion or return of customer personal data, per your entrustment contract.

How to Not Be Here Again: Pilot First, With Kill Conditions

Everything above is the cost of a relationship structured for entry and not for exit. The fix at the next signing is not a longer contract — it is a shorter first commitment with defined outcomes.

Structure the start as a three-month pilot with the exit conditions written in advance: what will be true at the end of month three if this is working (specific, measurable, agreed by both sides), what happens if it is not, and what notice applies during and after. Then attach the four ownership clauses that matter — store contract in your name, master account held by you, copyright assignment naming adaptation and derivative-work rights, data return on termination — and treat resistance to them as information about the agency rather than a negotiation to win. A partner planning a long relationship has no reason to object to a clean exit; one relying on lock-in does. The same logic governs how you evaluate candidates in the first place, which we lay out in our comparison of Japan EC agency types.

Common Mistakes

The patterns repeat. Serving notice before confirming who owns the store. Assuming paid-for content is owned content. Letting an agency open the store in its own name to save a few weeks of application work. Not exporting ad data until after the relationship has soured. Timing the switch into a major campaign period because the contract happened to end there. And replacing an agency without diagnosing the problem — if the brief was unclear, the budget too small, or nobody on your side owned the relationship, the second agency fails the same way as the first.

How LAUNOVA Helps

LAUNOVA works exclusively with overseas brands selling in Japanese ecommerce — Rakuten Ichiba, Amazon Japan, Yahoo! Shopping, and Shopify. Taking over from an incumbent is a normal way brands start with us, and we scope it as its own piece of work rather than a free extra attached to signing: establishing who holds each platform contract and master account before anything is announced, building the recovery list, running the handover against a written checklist like the one above, and where timing allows operating in parallel with the outgoing team so the store is never unattended. From there it becomes ordinary operations — the day-to-day work described in our Japan EC operations service, with account ownership and data access on your side from the first day.

What we do not do is give legal or tax advice. Contract interpretation, copyright assignment wording, trademark disputes, and personal-data obligations belong with a Japanese lawyer, benrishi, or tax adviser, and we will say so when you reach that line. Engagements are scoped to your situation rather than sold from a rate card — tell us which platforms you are on and whose name the store is in, and we will tell you what your exit actually looks like →

FAQ

Q: Who owns my Rakuten store account — me or my agency?
It depends on whose name the store contract is in, and you answer that by reading the contract rather than assuming. If your own company is the merchant on the Rakuten Ichiba store contract, the store is yours and your agency holds delegated access through RMS user accounts you can revoke. If the agency opened the store under its own corporate name, the store belongs to the agency, and moving it to you is not a settings change: Rakuten states that changing a store contract to a different legal entity is only possible with its prior consent, and routes genuine cases such as business transfers, mergers, and company splits through a formal application. Check the merchant name on the contract and on your RMS master account before doing anything else.

Q: Can I take my reviews and sales history to a new store?
If you keep the same store account and only change who operates it, nothing happens to your reviews, ratings, or history — they attach to the account, not to the operator. If you have to open a new store because the old one was in someone else’s name, you start from zero: Rakuten shop reviews attach to the store, Amazon seller feedback attaches to the seller account, and Amazon product reviews attach to the ASIN rather than to you. Neither platform publishes a general mechanism for migrating reviews between separate stores or accounts. This is the single strongest financial argument for making sure the account is in your name from day one.

Q: Do I own the Japanese product copy and images my agency created?
Not automatically. The work-for-hire rule in Article 15 of Japan’s Copyright Act applies to work created by people within the organisation, not to work commissioned from an outside contractor, so copyright in commissioned copy and photography starts with whoever created it. Paying for the work does not transfer copyright by itself: the contract has to assign it, and Article 61(2) presumes the rights of adaptation and derivative-work use stay with the author unless named explicitly in the assignment clause. Moral rights cannot be assigned at all under Article 59, which is why Japanese contracts typically add a covenant not to exercise them. Have a Japanese lawyer check your wording — this is the clause foreign brands most often find missing at exit.

Q: How much notice do I have to give to end a Japan EC agency contract?
Whatever your contract says — Japanese EC agency contracts vary widely. Practitioner commentary and contract templates commonly describe one month of written notice as typical, with minimum terms quoted in the three-to-six-month range by agencies themselves, but there is no official statistic and no legal standard to fall back on. Separately, Article 651 of the Civil Code lets either party terminate a mandate at any time, though a party terminating at a time disadvantageous to the other, or terminating a mandate that also serves the mandatary’s interests, may owe damages unless there were unavoidable grounds. Treat that as a backstop, not a plan: read your notice clause, count backwards from your target switch date, and send notice in writing.

Q: Can LAUNOVA help me switch agencies or exit one?
Yes — that is a normal way brands start with us, and we treat it as its own piece of work rather than a free bonus attached to signing. We review who holds the store contract and the master account, list what has to be recovered before notice is served, run the handover against a written checklist, and where possible operate in parallel with the outgoing team so the store is never unattended. We do not provide legal or tax advice: contract interpretation, copyright assignment wording, and trademark questions belong with a Japanese lawyer or benrishi. Engagements are scoped to your situation rather than sold from a rate card — tell us which platforms you are on and who holds the account, and we will tell you what your exit actually looks like.
