The Benefits and the Caveats of a Standing Legal Retainer in Japan｜A Practical Assessment for Foreign Companies

Whether to put a Japanese law firm on a standing retainer is a decision that turns less on what such an arrangement is than on what it actually delivers and where it can disappoint. What follows is written for companies with customers, a subsidiary or an operating base in Japan, and sets out the benefits and the caveats under Japanese law and Japanese professional practice.

Advice before a dispute exists, not after

Where counsel is instructed matter by matter, a situation must deteriorate to the point of justifying an instruction before anyone picks up the telephone. A retainer lowers that threshold sharply: whether trading terms are too one-sided, whether a particular email should be sent at all, at what point shipments should stop once a customer starts paying late. None of these is yet a dispute, and all of them can be raised at once. Once a dispute has hardened, the range of available options narrows; what is dealt with beforehand costs least.

Speed of first response

Counsel found at short notice must be taken through the business, the history of the dealings and the relationships between the people involved, which routinely takes days or weeks. Retained counsel already holds that background and can move straight to assessment. In debt collection the first few weeks after a default frequently decide whether provisional attachment (kari-sashiosae) can be obtained before the debtor’s assets disperse; in an employment dispute, or a customer complaint, the quality of the first response is equally decisive.

Contract review and a systematic approach to receivables

Most matters that later become disputes were seeded when the contract was signed: no jurisdiction or governing law clause, no rate of late payment interest, no acceleration clause, no security. Review before signature removes those seeds. The same applies to receivables, where retained counsel can establish a standing method rather than improvising case by case.

Credit assessment before trading begins — checking the certificate of registered matters of the company, the equivalent certificate for its real property, and other public sources.
Acceleration clauses — providing that the whole debt falls due immediately on late payment, dishonour of a bill, attachment, or an application for insolvency proceedings.
Joint and several guarantees — taking a guarantee from a representative director or an affiliated company, subject to the restrictions the Civil Code of Japan imposes on personal guarantees.
Managing prescription — under the Civil Code as amended with effect from 1 April 2020, a claim is extinguished five years from the time the creditor became aware that the right could be exercised, or ten years from the time it could be exercised, whichever comes first. Where receivables are numerous, the dates of accrual and expiry warrant a periodic review.

Emergency access, and a basis for internal decisions

A bank account attached, a statement of claim served, a customer entering bankruptcy — in each of these the first few days shape the outcome. An answer must be filed by a fixed date, proofs of debt must be lodged within the period set in the insolvency proceedings, and neither deadline is easily recovered once missed. With retained counsel, contact is made the same day and the necessary steps are settled without first having to find a lawyer.

There is a further benefit that is easy to overlook. Staff inside the company regularly face calls they are not equipped to make: whether to accept a return, whether a demand can be refused, whether an employment relationship should be brought to an end. An opinion from retained counsel allows those decisions to rest on a stated basis rather than instinct, and leaves a record of how the decision was reached — which matters considerably if it is questioned later.

What to settle before signing

The boundary of the fee — what the monthly fee covers and what is billed separately should be recorded in writing at the outset. As a rule routine advice and document review fall within it, while litigation, provisional remedies and compulsory execution attract a separate initial fee (chakushukin) and success fee. Any cap on the number of enquiries or hours per month should be confirmed as well.
Cost against use — a retainer is poor value if it is rarely called upon. It should be used in earnest once signed; conversely, a company with one or two legal questions a year is better served by instructing counsel matter by matter.
Fit with the firm’s specialisation — practices differ. A company whose principal need is debt collection should ask about the firm’s record in provisional remedies and compulsory execution; a company whose concerns are chiefly employment matters should ask about something else.
Conflicts of interest — a Japanese lawyer may not act in a matter adverse to an existing client, under the Attorney Act and the rules of professional ethics. Naming principal counterparties and competitors before signing allows any conflict to be identified in advance.

Points for a foreign company to confirm

Working languages — the language of discussion, the language in which advice and documents are issued, and which side bears translation costs.
Time difference and access — how Japanese office hours sit against the head office’s, whether contact outside those hours is possible in an emergency, and which channels are used.
Reporting — whether reports are issued at fixed intervals, in what language and format, and how far information is shared between the parent and the Japanese subsidiary.
Division of work in a dispute — how responsibility is allocated between home-country counsel and Japanese counsel, and which of them coordinates the whole.

In closing

A retainer is not necessary for every company. For a company trading in Japan on a continuing basis, however, its value lies less in resolving disputes than in preventing them, and in making the first step the right one at the moment a dispute begins. Our practice is centred on debt collection and corporate legal work, and we accept both retainers and individual instructions from foreign companies with customers or a subsidiary in Japan. We are equally glad to work through the company’s own counsel abroad.
