Why This Decision Matters
Your choice of KK or GK is not a formality — it shapes your banking relationships, investor credibility, administrative overhead, and market perception for the entire life of your Japan operation. Many foreign founders pick the wrong one and restructure later at significant cost.
This guide breaks down the real-world differences and helps you decide.
The Two Options
| Feature | 🏢 KK (株式会社) | 🏠 GK (合同会社) |
|---|---|---|
| English equivalent | Corporation / Co., Ltd. | LLC |
| Legal basis | Companies Act, Part II | Companies Act, Part III |
| Ownership unit | Shares (株式) | Membership interests (持分) |
| Foreign ownership | ✅ 100% permitted | ✅ 100% permitted |
| Minimum capital | ¥1 (legal minimum) | ¥1 (legal minimum) |
| Market perception | Gold standard — expected by banks, enterprise clients, government | Acceptable — Amazon Japan & Apple Japan operate as GK |
| IPO / fundraising capable | ✅ Yes | ❌ No (must convert to KK) |

Setup Costs — Side by Side
| Cost Item | KK | GK |
|---|---|---|
| Registration tax (Legal Affairs Bureau) | ¥150,000 | ¥60,000 |
| Notary fee (Articles of Incorporation) | ¥30,000–50,000 | ¥0 (not required) |
| Stamp duty (paper filing) | ¥40,000 (waived if e-filed) | ¥40,000 (waived if e-filed) |
| Corporate seal (法人印鑑) | ~¥10,000–30,000 | ~¥10,000–30,000 |
| Total government fees | ||
| Professional service (bilingual) | From ~$3,000 | From ~$1,700 |
💡 The KK costs roughly 3× more than a GK at incorporation. But the cost gap narrows quickly once you factor in ongoing operations — both pay the same taxes, same social insurance, same accounting fees.

The Banking Question — Where KK Wins
🏦 This is where KK's extra cost pays for itself.
Japanese corporate banks — particularly the Big Three (MUFG, SMBC, Mizuho) — have strict internal risk-assessment criteria for account opening. Foreign-owned companies face additional scrutiny under post-2016 AML/KYC rules.
| Banking Factor | KK | GK |
|---|---|---|
| Perception by major banks | ✅ Familiar, credible | ⚠️ Less established perception |
| Account opening success rate | Higher | Lower (but improving) |
| Investor / partner confidence | ✅ Expected for B2B | ⚠️ May raise questions |
| Government contract eligibility | ✅ Standard | ⚠️ May face limitations |
💡 Practical reality: While a GK can open bank accounts, the process is smoother and faster with a KK. If banking is critical for your operations (and it almost always is), the extra ¥100,000–150,000 in setup costs is well worth it.
The Director Question
Legal Position (2026)
Since March 2015, the Companies Act does not require a Japan-resident director for either KK or GK. All directors and shareholders may reside overseas.
Practical Reality
⚠️ While not legally required, having a Japan-resident director is strongly recommended — especially for banking.
| Scenario | Without JP Resident Director | With JP Resident Director |
|---|---|---|
| Incorporation | ✅ Possible | ✅ Possible |
| Corporate bank account | ❌ Very difficult — most major banks require in-person visit by a representative with JP address | ✅ Significantly easier |
| Business Manager visa | ❌ Cannot apply (no presence in Japan) | ✅ Required for visa |
| Day-to-day operations | ⚠️ Limited — signing contracts, receiving registered mail | ✅ Full operational capability |
| Tax authority correspondence | ⚠️ Need separate tax agent | ✅ Direct communication |
💡 Our recommendation: If you're incorporating remotely, consider appointing a qualified Japan-resident representative director. This doesn't mean giving up control — directorship arrangements can be structured to maintain your authority while satisfying banking and operational requirements.
When to Choose KK
| Scenario | Why KK |
|---|---|
| 🏦 Need corporate bank account quickly | KK signals credibility to Japanese banks |
| 💼 Enterprise B2B clients | Japanese corporates expect 株式会社 on contracts |
| 📈 Plan to raise investment | Shares are the standard equity instrument |
| 🤝 Joint venture with Japanese partner | KK provides proper shareholder governance |
| 🏛️ Government contracts | KK is the expected form |
| 🛂 Business Manager visa planned | KK provides strongest visa application foundation |
| 🔮 Long-term Japan commitment | Structure that grows with you |
When to Choose GK
| Scenario | Why GK |
|---|---|
| 💰 Budget-conscious setup | Saves ~¥150,000+ in government fees |
| 🏭 Wholly-owned subsidiary | No external shareholders = no need for KK governance |
| 🧪 Market testing | Fast setup (as little as 7 business days), easy to convert later |
| 🔧 Operational simplicity | No annual meeting obligations, no public disclosure |
| 🌐 Amazon / Apple model | Both operate major Japan businesses as GK |
| 📦 Import-only with ACP | Structure is secondary when ACP handles customs |
Can You Convert GK → KK Later?
Yes. The Companies Act permits converting a GK to a KK (組織変更). However, it involves:
| Step | Cost / Time |
|---|---|
| Shareholders' (members') resolution | Internal |
| New Articles of Incorporation drafted | Professional fees |
| New registration tax (KK rate) | ¥150,000 |
| Notarization of new Articles | ¥30,000–50,000 |
| Legal Affairs Bureau re-registration | 2–4 weeks |
| Bank account / contracts updated | Administrative overhead |
| Total cost | ¥300,000–500,000+ |
⚠️ Conversion is possible but not free. If there's a reasonable probability you'll need KK-level credibility within 2 years, starting as KK is more cost-effective than converting later.
