When it comes to incorporating a company in Japan, most foreign founders end up deciding between two main structures: the Godo Kaisha (GK) and the Kabushiki Kaisha (KK). Both are limited liability companies under Japanese law, but how they operate, how they’re perceived, and how they’re maintained can be very different.
Choosing the right structure from the start isn’t just a paperwork decision. It can impact how easy it is to open a bank account, bring on investors, hire staff, or even get approved for a visa. And while both GK and KK are legitimate company types, each comes with trade-offs that only really become clear once you’re up and running.

Quick Refresher: What Is a GK and What Is a KK?
Before we get into the details of which structure to choose, here’s a quick refresher: a Godo Kaisha (GK) is Japan’s version of a limited liability company (LLC), while a Kabushiki Kaisha (KK) is a joint-stock company with a more formal governance structure.
Both are legal entities recognized under Japanese corporate law, and both offer limited liability protection. However, a GK is typically easier and faster to set up, with fewer formalities and lower costs. A KK, on the other hand, carries more prestige and is often viewed more favorably by Japanese banks, large clients, and potential investors.
GK vs KK: Side-by-Side Comparison Table
| Feature | Godo Kaisha (GK) | Kabushiki Kaisha (KK) |
| Legal structure | LLC-style | Joint-stock company |
| Setup cost | Lower | Higher (notarization required) |
| Governance | Simple, flexible | Requires formal governance (board, meetings) |
| Credibility with banks/clients | Moderate | High |
| Foreign perception | Suitable for startups and SMEs | Seen as more established |
| Fundraising | Harder to attract VC | VC-friendly, allows for share issuance |
| Taxation | Same as KK | Same as GK |
| Investor/shareholder structure | Members (more informal) | Shareholders (formalized roles) |
When a GK Makes Sense: Scenarios and Use Cases
For many foreign founders, especially those just entering the Japanese market, a Godo Kaisha (GK) is often the most straightforward and cost-effective option. It’s well-suited for lean teams, solo founders, and early-stage businesses that want to get up and running quickly without the extra layers of corporate governance that come with a KK.
If you’re launching a consultancy, service-based business, or tech startup, a GK offers the flexibility you need without the overhead. You don’t need to appoint a board of directors or hold annual shareholder meetings, which reduces your admin burden and keeps things simple as you scale.
A GK is also a good fit for first-time foreign entrepreneurs, especially those without a Japanese co-founder or resident director. The setup process is faster and more forgiving, and the lower upfront cost makes it easier to test the waters before committing to a larger investment.
It’s not about cutting corners, it’s about choosing a structure that matches your current stage and operating model, while still providing room to grow.
When a KK is the Smarter Choice
While a GK offers speed and simplicity, there are plenty of situations where a Kabushiki Kaisha (KK) is the better long-term move, especially if reputation, scale, or outside investment are part of your business plan.
If you’re operating in a high-trust industry like finance, healthcare, law, or manufacturing, a KK is often seen as more established and credible in the eyes of Japanese partners, banks, and government agencies. In fact, some enterprise clients or public sector contracts may require you to operate as a KK to even be considered.
A KK also gives you more flexibility when it comes to fundraising and ownership structure. You can issue shares, take on outside investors, and structure dividends in a way that’s familiar to both Japanese and international stakeholders. This makes it far easier to bring on venture capital or prepare for future M&A activity.
If your goal is to scale the business, transfer ownership, or build long-term market presence in Japan, a KK gives you the structure and credibility to do it. The incorporation setup is a bit more involved—and there are more compliance steps post-launch—but for many growing companies, it’s well worth the tradeoff.
Key Legal and Administrative Differences to Know
| Category | Godo Kaisha (GK) | Kabushiki Kaisha (KK) |
| Notarization | Not required | Required for Articles of Incorporation |
| Articles of Incorporation | Simple structure, fewer formalities | More detailed, must outline governance structure |
| Registration Costs | Lower (approx. ¥60,000) | Higher (approx. ¥150,000 + notarization fees) |
| Governance Requirements | No board or shareholder meetings required | Requires formal governance: board, shareholders, etc. |
| Ongoing Compliance | Minimal | Regular board/shareholder meetings and documentation |
| Setup Timeline | Slightly faster (1–3 weeks) | Slightly longer (2–4 weeks) |
While both GKs and KKs follow Japan’s corporate laws, the administrative burden and formal requirements are noticeably different. A GK is quicker and cheaper to set up, with no need to notarize your Articles of Incorporation and far fewer governance obligations post-launch. There’s no board of directors, no need for annual shareholder meetings, and overall, the structure is much more hands-on and founder-friendly.
A KK, on the other hand, involves more upfront cost and complexity. You’ll need to get your Articles notarized, appoint directors, and follow stricter compliance rules including formal board resolutions and shareholder approvals for key decisions. While this adds some friction, it also gives the company a more robust governance framework, which is often expected in corporate and institutional environments.
Choosing between them often comes down to how lean or formal you want your setup to be and how much structure you’ll need as the business grows.
Can a GK Convert to a KK Later?
Yes, it’s possible to convert a Godo Kaisha (GK) into a Kabushiki Kaisha (KK) and some businesses do choose this route after launching. But it’s not as simple as flipping a switch. The process is essentially a corporate restructuring, involving legal filings, tax considerations, and, in some cases, a complete overhaul of your governance and ownership structure.
Many founders choose to start with a GK because it’s faster, cheaper, and less complex, then plan to “upgrade” to a KK later if the business gains traction. While this strategy can work, it’s important to know what you’re signing up for. Converting from GK to KK means drafting new Articles of Incorporation, going through notarization, updating tax registrations, and possibly renegotiating bank relationships or contracts. It’s not uncommon for businesses to face downtime or added administrative costs during the transition.
In some cases, waiting to incorporate as a KK from the start is the smarter move, especially if you plan to raise capital, build a local team, or work with large Japanese clients early on. Switching structures later can add complexity at a moment when you’d rather be scaling.
That said, if you’re entering the market lean and want to prove your model first, starting as a GK can still make sense as long as you go in with a clear timeline and plan for conversion if and when it becomes necessary.
Taxation: No Difference, But Reporting and Optics Matter
From a tax standpoint, there’s no difference between a GK and a KK. Both are treated as corporations under Japanese tax law and are subject to the same rules around corporate tax, consumption tax (VAT), and withholding tax, depending on business activities and revenue thresholds.
However, in practice, there can be subtle differences in how the two structures are perceived both by tax authorities and external stakeholders. A KK is often seen as more formal and fully established, which may lead to greater scrutiny in financial reporting, but also carries an expectation of stronger internal controls.
Some foreign investors, enterprise clients, and Japanese banks also tend to view KKs as more “serious” or “trustworthy” from a compliance and governance perspective. That doesn’t mean a GK is inherently riskier, but it’s something to be aware of if your business will involve external audits, public sector work, or due diligence processes.
If your company plans to stay lean and self-funded, this likely won’t be a major issue. But if you’re preparing for fundraising, partnerships, or expansion, the optics of your corporate structure could carry more weight than the tax treatment itself.
How Foreign Ownership Impacts the Decision
One of the biggest practical differences between a GK and a KK for foreign founders comes down to who can run the company and where they need to be based.
A Godo Kaisha (GK) can be formed and managed without a resident director in Japan, making it a more flexible option for foreign entrepreneurs setting up remotely. This is especially helpful for founders testing the market before relocating, or for companies running Japan operations from overseas in the early stages.
A Kabushiki Kaisha (KK), on the other hand, typically requires at least one director who is a resident of Japan. This doesn’t necessarily mean a Japanese national, but it does mean someone with a valid visa and address in Japan. For foreign companies without a local partner or representative, this can be a setup hurdle that requires either a nominee director or a visa-backed relocation plan.
There are also visa implications to consider. If you’re applying for a Business Manager Visa, both GK and KK are eligible structures, but KKs tend to carry more weight with immigration authorities due to their formal governance and capital structure. That said, it’s entirely possible to obtain the visa with a GK if the business plan, capital, and office setup meet the criteria.
In short, GKs offer more flexibility during setup, but KKs may offer smoother pathways if your expansion involves immigration, funding, or hiring.

GK or KK? Choose the Structure That Sets You Up to Grow
Both Godo Kaisha (GK) and Kabushiki Kaisha (KK) are viable, limited liability structures for incorporating in Japan, but they serve different needs. GKs are faster, simpler, and more flexible, ideal for small teams or first-time market entry. KKs offer more credibility, stronger governance, and investor-ready structure, making them better suited for companies planning to scale, raise funds, or work with large Japanese partners. The best choice depends on your business goals, stage, and the level of structure your operations require.
