Should You Register Your Akiya as a Sole Proprietor Business?

Should You Register Your Akiya as a Sole Proprietor Business?

If you’ve purchased or are considering purchasing an akiya in Japan, you may be wondering whether you should register it as a business. Especially for those planning to rent it out as a guesthouse, Airbnb, artist residency, or community space, the idea of becoming a sole proprietor (kojin jigyō) may seem appealing—but is it worth it?

In this guide, we’ll walk through what it means to register your akiya-related activity as a business, the pros and cons of going the sole proprietor route, and how Old Houses Japan can help you decide if it’s the right move.

What Is a Sole Proprietor in Japan?

A sole proprietor in Japan is an individual who operates a business under their own name or a trade name, without forming a separate legal entity (like a corporation). It’s the simplest and most common structure for small businesses and freelancers.

Registering as a sole proprietor (個人事業主 / kojin jigyōnushi) allows you to:

• Report business income and expenses
• File a tax return as a business
• Deduct costs related to renovations, utilities, and operations
• Open a business bank account
• Legally offer services or rentals tied to your property

You can register at your local tax office (zeimusho) by submitting a simple form called the Notification of Sole Proprietorship Start (個人事業の開業届出書).

When Does Registering Make Sense?

Registering your akiya as a sole proprietorship makes the most sense when:

• You plan to generate income from the property (e.g., guesthouse, Airbnb, artist space)
• You expect to invest heavily in renovation or maintenance
• You want to deduct those costs from your taxable income
• You plan to hire help, apply for subsidies, or work with contractors

If your akiya is purely a personal vacation home or you're not planning to generate income with it anytime soon, registration may not be necessary—yet.

Benefits of Sole Proprietorship for Akiya Owners

✅ Tax Deductions: You can deduct business-related expenses including:

• Repairs and renovation work
• Utility bills
• Marketing costs (e.g., website, photos)
• Professional services (legal, accounting)

✅ Eligibility for Subsidies: Some rural areas offer grants and support to individuals starting small businesses—particularly guesthouses, community spaces, and tourism initiatives.

✅ Business Identity: It becomes easier to open business accounts, work with professionals, and establish trust if you’re formally registered.

✅ Flexibility: Unlike corporations, sole proprietorships have fewer regulations and can be easily changed or dissolved.

Challenges to Consider

⚠️ You’ll Need to File Taxes in Japan: If you’re a resident, you’ll file a tax return locally. If you’re abroad, you may need a tax agent or representative.

⚠️ Local Zoning Restrictions: Not all akiya are in zones that permit lodging or commercial use. You’ll need to check with the city office or building department before registering.

⚠️ Short-Term Rental Licensing (Minpaku): If you plan to operate an Airbnb or short-stay rental, you’ll need to apply for a Minpaku license and meet health, safety, and operational requirements.

⚠️ Language Barriers: Most registration and tax documents are in Japanese. It’s highly recommended to work with a bilingual liaison or advisor.
