Amending a Japan KK or GK's registered business purpose (目的) clause requires a shareholders' or members' resolution to change the Articles of Incorporation (定款), then a registration filing with the Legal Affairs Bureau (法務局). A KK needs a special shareholders' resolution; a GK generally needs unanimous member consent unless its articles state otherwise. The filing carries a flat registration tax (登録免許税) of at least ¥30,000, on top of professional fees.
How Do You Amend the Business Purpose Clause After Incorporation?
You change the wording of the 目的 clause inside the Articles of Incorporation (定款), then register that change at the Legal Affairs Bureau (法務局) so the new activity appears on the company's public registration record (登記事項証明書). This is a two-step process, not a single filing: the corporate resolution comes first, the registry update comes second, and the second step is what actually makes the new business line visible to banks, customs brokers, and counterparties who check the registry.
Most foreign owners run into this because the company was formed with a narrow 目的 clause and the business has since grown into something the clause does not cover. Our Articles of Incorporation drafting guide covers how to write the clause broadly enough at incorporation to avoid this problem entirely, including the catch-all language that absorbs adjacent activities without a future amendment. If that step was skipped, or the company was formed before the new business line existed, amendment is the only route back into compliance.
What Approval Does a KK Need Versus a GK?
A KK amends its Articles of Incorporation (定款) through a special resolution at a shareholders' meeting (株主総会); a GK amends its articles through unanimous consent of its members unless the GK's own articles set a different voting rule. This is a structural difference between the two entity types, not a formality difference. The KK route runs through a shareholders' meeting with a supermajority voting threshold on the resolution; the GK route is member-based and generally requires all members to agree, because a 合同会社 (GK) is legally a partnership-style entity where the members are also its governing body.
For a single-owner or closely-held foreign subsidiary, both routes are usually a paperwork exercise rather than a governance fight. Where friction shows up is a KK with multiple unrelated shareholders, or a GK where a co-invested member disputes the direction of the new business line. Our Japan company incorporation guide sets out how KK and GK governance differs from formation onward, which is the same difference that resurfaces here at amendment time.
How Long Does the Amendment Take and What Does It Cost?
The corporate resolution and the registration filing typically run within two to three weeks combined once the new 目的 wording is settled: the resolution is passed, then the registration filing goes to the Legal Affairs Bureau (法務局) within the statutory filing period following the resolution date. The registration tax (登録免許税) is a flat amount starting at ¥30,000 regardless of the company's capital, and a judicial scrivener (司法書士) handling the filing typically adds a further ¥30,000 to ¥50,000 in professional fees for a KK.
The flat registration tax is a useful planning fact: it does not scale with company size or the number of new business lines added in the same filing, so bundling several intended activities into a single amendment is usually cheaper than amending twice. What does scale is drafting time and the professional fee, particularly where the new 目的 wording needs to be specific enough to satisfy a bank or regulator but broad enough to avoid a third amendment in two years.
Key points:
(a) A KK amendment moves through a special shareholders' resolution; a GK amendment moves through member consent under the GK's own articles. (b) The registration filing at the Legal Affairs Bureau (法務局) follows the resolution and carries a flat registration tax (登録免許税) of at least ¥30,000, separate from any judicial scrivener (司法書士) fee. (c) Registering the new purpose is a corporate-law step only; it does not itself authorize a regulated activity that needs its own government license (許認可).
Does Adding a Business Purpose Automatically Let You Start the New Activity?
No. Registering a new 目的 clause changes what the company is legally permitted to describe itself as doing; it does not grant any sector-specific license (許認可) that the activity itself requires. Food retail, labor dispatch (人材派遣), pharmaceutical sales, and a range of other regulated activities each require their own government license or permit, obtained from the relevant ministry or prefectural authority, on top of and separate from the 目的 clause covering that activity.
This is the step foreign owners most often assume is bundled into the amendment and it is not. A company can have a perfectly compliant, broadly worded 目的 clause and still be operating illegally in a licensed sector because the license itself was never filed for. Our business license guide walks through which activities trigger a separate license requirement and which ministry issues each one; treat that as the next question to answer once the 目的 amendment itself is settled.
What Actually Triggers This Problem?
The most common trigger is a bank or a customs broker refusing to process a transaction because the registered 目的 clause does not describe the activity the company is actually conducting. A bank reviewing a wire transfer, or a customs broker reviewing an import declaration, checks the registry copy of the Articles of Incorporation (定款) against the transaction in front of them, and a mismatch is grounds to decline or hold the transaction rather than interpret the clause generously.
This pattern shows up with particular frequency where a company was bought as an existing shell rather than formed fresh, because a dormant KK or GK's original 目的 clause was written for whatever business the prior owner ran, not the one the new owner intends. Our shell company acquisition guide covers exactly this mismatch for buyers solving Japan's bank account approval problem by acquiring an existing entity rather than incorporating new. In both the shell-acquisition case and the organic-growth case, the fix is the same amendment process described above, run before the bank or broker forces the issue rather than after.
Frequently Asked Questions
Can I add a new business line to my Japan KK without touching the Articles of Incorporation?
No. The business purpose (目的) clause inside the Articles of Incorporation (定款) is the legal record of what activities the company is authorized to describe itself as conducting, and it is a publicly registered item under the Companies Act (会社法). Any activity outside the current clause requires an amendment before you can point to a compliant registry record for that activity.
Does amending the 目的 clause require both a resolution and a separate registration filing?
Yes, and treating them as one step is the most common mistake. The resolution changes the Articles of Incorporation (定款) internally; the registration filing at the Legal Affairs Bureau (法務局) is what updates the public record that banks, customs brokers, and regulators actually check, and it must happen after the resolution within the statutory filing period.
If my new business is a licensed activity, does the 目的 amendment cover the license too?
No. The amendment only updates what the company is permitted to describe itself as doing; it does not substitute for a sector-specific license (許認可) such as those required for food retail, labor dispatch, or pharmaceutical sales. Those licenses are separate applications to the relevant ministry or authority and typically need to be filed in addition to, not instead of, the 目的 amendment.
Conclusion
Adding a new business line to an existing Japan KK or GK is a two-step corporate process: a resolution changing the Articles of Incorporation (定款), followed by a registration filing at the Legal Affairs Bureau (法務局), with a flat registration tax (登録免許税) starting at ¥30,000. It changes what the registry says the company does; it does not by itself unlock a regulated activity that carries its own license requirement. Foreign owners typically discover the gap when a bank or customs broker flags the mismatch, which makes this a problem worth resolving proactively rather than reactively.
