GK vs KK in Japan: Godo Kaisha vs Kabushiki Kaisha Compared (2026)

When starting a business in Japan, most founders choose between two company structures. These are the kabushiki kaisha (KK) and the godo kaisha (GK).

A kabushiki kaisha (株式会社) is a joint stock company. Shareholders own it, and directors run it. Most KKs are private, and a small KK can operate with one director.

A godo kaisha (合同会社) is a limited liability company, often called the Japanese LLC. Its members own the company and usually manage it directly.

The key differences between KK and GK:

• Setup cost: A KK pays at least ¥150,000 in registration tax plus notary fees. A GK pays at least ¥60,000 and needs no notarization.

• Credibility: Japanese banks and business partners know the KK best.

• Fundraising: Only a KK can issue shares to investors or list on a stock exchange.

• US tax: A GK can be a disregarded entity for US tax. A KK cannot.

Both offer limited liability, and Japan taxes both at the same corporate rates. In 2025, GKs made up 28.6% of new corporations in Japan.

Godo kaisha vs kabushiki kaisha: Which one should you choose?

Choose a Godo Kaisha (GK) if:

• You are a solo founder, freelancer, or small team

• You do not plan to raise venture capital or issue shares

• You want faster setup, lower costs, and simpler governance

• You prefer direct control over company management

• You are testing the Japanese market or launching a lean operation

Startups, consultants, and foreign founders often choose a GK. They value flexibility and speed over formality.

Choose a Kabushiki Kaisha (KK) if:

• You plan to raise capital, issue equity, or bring in investors

• You want maximum credibility with Japanese corporations, banks, or enterprise clients

• You expect long-term growth, M&A activity, or a future IPO

• You plan to hire at scale in Japan

• You want a structure that Japanese stakeholders instantly recognize

KKs are often preferred by venture-backed startups, established foreign companies, and businesses planning deep integration into the Japanese market.

Quick takeaway

• GK = flexibility, speed, lower cost, founder control

• KK = fundraising, credibility, scalability, long-term growth

Many companies start as a GK and convert to a KK once they raise funds or expand. Plan for about two months, because conversion includes a creditor notice period.

What is a Kabushiki Kaisha?

A kabushiki kaisha (株式会社), or KK, is a joint stock company under Japan’s Companies Act. In English, KKs often add “K.K.” or “Co., Ltd.” to their names.

The KK structure resembles an American C corporation. Shareholders own the company through shares, and directors manage it.

A KK can issue new shares to raise capital from investors. Investors can later sell their shares, which gives them an exit.

KK governance rules

Governance depends on the KK’s size and share rules:

• A private, non-large KK can have just one director. A board of directors and a statutory auditor are optional.

• A KK that sets up a board of directors needs at least three directors.

• A listed KK must also follow the Financial Instruments and Exchange Act.

Every KK holds an annual shareholders’ meeting and publishes a yearly balance sheet notice.

Why KKs carry credibility

The first KK formed in 1873. Japanese customers, employees, and business partners still see the KK as the standard company type.

Examples of US/International KK companies in Japan

• Disney—ウォルト・ディズニー・ジャパン株式会社

• Kearney—A.T. カーニー株式会社

• Nestle—ネスレ日本株式会社

• Godiva—ゴディバ ジャパン株式会社

• Gap—ギャップジャパン株式会社

• Zara—株式会社ITXジャパン

• Adidas—アディダスジャパン株式会社

What is a Godo Gaisha?

A godo kaisha (合同会社), also spelled godo gaisha or G.K., is a limited liability company under the Companies Act. Japan introduced it in 2006, modeled on the American LLC.

A GK cannot issue shares or list on a stock exchange. Its owners are called members (社員, shain), not shareholders.

Members invest capital and usually manage the company themselves. The articles of incorporation can instead name executive members and a representative member (代表社員).

Why founders choose a GK

• Lower setup cost: No notarization, and the registration tax minimum is ¥60,000.

• Simpler governance: No board of directors or shareholders’ meetings required.

• Flexible profits: The articles of incorporation can split profits differently from capital contributions.

• No public financial notice: Unlike a KK, a GK does not publish its balance sheet.

Both a KK and a GK can start with ¥1 in capital, so low capital is not a GK-only advantage.

Setup includes registering with the Legal Affairs Bureau and obtaining a company seal. See our full guide to setting up a business in Japan.

GKs are growing fast. In 2025, founders formed 44,991 GKs, up 6.8% from the year before. Check out the brand names that run in Japan as a GK.

• Google—グーグル合同会社

• Cisco—シスコシステムズ合同会社

• Universal Music—ユニバーサル ミュージック合同会社

Comparison: Godo kaisha vs. kabushiki kaisha

This comparison table shows the key differences between KK and GK.

Kabushiki kaisha vs godo kaisha comparison table

a. Governing laws

The Companies Act governs both KK and GK. Only a listed KK must also follow the Financial Instruments and Exchange Act.

Most KKs are private, so the same law applies to both in practice. The real difference is how much governance each requires.

b. Ownership structure

A KK separates ownership from management. Shareholders own the company, and directors run it, though one person can do both.

In a GK, members own the company and usually manage it too. This suits founders who want direct control.

c. Management

A KK makes decisions through directors and shareholders’ meetings. Larger KKs add a board of directors and auditors.

A GK runs on its articles of incorporation. Members decide most matters themselves, so decisions move faster.

d. Liability

Both entity types offer limited liability. Shareholders in a KK and members in a GK risk only the amount they invested.

Neither structure exposes owners’ personal assets to company debts. By contrast, members of a gomei kaisha carry unlimited liability, which is why few founders choose it.

e. Tax implications

Japan taxes a KK and a GK the same way. Both pay corporate tax at the same rates, and owners pay tax on dividends or distributions.

The difference is US tax. The IRS treats a KK as a per se corporation, which cannot change its classification.

A GK can elect disregarded entity status for US tax. This lets a US parent treat the GK like a branch. That makes a GK attractive for US-owned subsidiaries.

For US-owned companies, a GK can be more tax-efficient. Your best choice depends on your ownership and goals, so check with a tax professional.

Can you change from a Godo Kaisha to a Kabushiki Kaisha later?

Yes. Many companies in Japan intentionally start as a Godo Kaisha and later convert to a Kabushiki Kaisha as their business grows.

This is a common strategy for foreign founders, startups, and international companies entering the Japanese market.

A GK suits the early stages because setup is cheaper and governance is simpler. See the “Choose a GK if” checklist above.

Why companies start as a GK

A Godo Kaisha is often chosen in the early stages because it offers:

• Faster and less expensive setup

• Simpler governance and decision-making

• Greater flexibility for founder-led operations

• Lower administrative overhead during market entry

For businesses validating demand or operating lean, a GK minimizes friction.

Why companies later convert to a KK

As a company matures, converting to a Kabushiki Kaisha becomes attractive when:

• External investors or venture capital are involved

• Equity issuance or stock options are required

• Enterprise clients expect a KK structure

• Long-term expansion or M&A is planned

• Hiring and scaling in Japan accelerates

A KK provides a structure that aligns better with growth, fundraising, and institutional expectations.

How long does GK to KK conversion take?

Plan for about two months. The process follows these steps:

• All members consent to a conversion plan.

• The company publishes a notice in the official gazette (官報, kanpō).

• Creditors get one month to object.

• The company registers as a KK with the Legal Affairs Bureau.

Conversion also works the other way. Amazon Japan converted from a KK to a GK.

Strategic takeaway

• GK is ideal for entry and early-stage operations

• KK is ideal for scale, capital, and long-term positioning

Choosing a GK does not limit future growth—it often enables it.

Frequently asked questions

What is the difference between kabushiki kaisha and godo kaisha?

A kabushiki kaisha (KK) is a joint stock company owned by shareholders and run by directors. A godo kaisha (GK) is a limited liability company whose members usually own and manage it. A KK costs more to set up and carries more credibility, and only a KK can issue shares. Both offer limited liability and pay the same Japanese corporate tax rates.

What does kabushiki kaisha mean?

Kabushiki kaisha means share company or joint stock company. The word combines kabushiki (株式, shares) and kaisha (会社, company). Japanese speakers pronounce it kabushiki gaisha, so you will see both spellings. Companies often write K.K. or Co., Ltd. after their English names.

What is a godo kaisha?

A godo kaisha (GK) is a limited liability company under the Companies Act of Japan. Godo (合同) means “joint,” so the name translates as “joint company.” It is often called the Japanese LLC. Its owners are members (社員), who usually manage the company themselves. Japan introduced the GK in 2006.

Is a GK lower status than a KK?

No. A GK has the same legal status as a KK under the Companies Act. Apple Japan, Amazon Japan, and Google Japan all operate as GKs. Some Japanese banks and business partners still know the KK better, so a KK can help with credibility.

Which is cheaper to set up, a KK or a GK?

A GK is cheaper. Its registration license tax starts at ¥60,000, and it needs no notarization. A KK pays at least ¥150,000 in registration tax plus ¥15,000 to ¥50,000 for notarization. Paper articles of incorporation add a ¥40,000 revenue stamp for either entity type. See the real cost of starting a business in Japan.

Can a foreigner own or run a KK or GK?

Yes. Japanese law has no nationality requirement for a representative director of a KK or a member of a GK. Since March 2015, every representative director can even live overseas. To manage the business from Japan, you still need a suitable visa, such as the Business Manager visa.

Can you convert a GK to a KK later?

Yes. All members must consent, and the company must publish a notice in the official gazette. Creditors get one month to object. Plan for about two months in total. Companies can also convert from a KK to a GK, as Amazon Japan did.

What is the US equivalent of a KK and a GK?

A KK is closest to a US C corporation, and a GK is closest to a US LLC. For US tax, the IRS treats a KK as a per se corporation. A GK can elect disregarded entity status, which suits US parent companies. Japan still taxes a GK as a corporation.

Wrapping it up

Choose a KK if you need investors, shares, or maximum credibility with Japanese business partners. Choose a GK if you want lower costs, simpler governance, and direct control.

Either way, you can convert later as your business grows. For costs in detail, see the real cost of starting a business in Japan.
