How to Freelance in Japan [Your Paperwork Checklist]

Interested in how to freelance in Japan as a foreigner? Specifically, what paperwork should you complete to make it official? 

We’ve put together this paperwork checklist for freelancing in Japan to help you out. 

Here are the 4 to 5 pieces of paperwork that are essential to file + some other considerations to get your freelance career in Japan off to a good start. 

1. Notification of Opening a Sole Proprietorship [開業届]

The official title of this form is 「個人事業の開業・廃業等届出書」= kojinjigyou no kaigyou, haigyou nado todokede sho, translated as "Notification of Opening or Closing of a Sole Proprietorship." 

Often, it is simply referred to as 開業届 = kaigyou todoke.

This form notifies your tax office that you are starting up a business, and you are required to submit it within a month of starting your freelance career. We have an article dedicated to this topic: Sole Proprietorship in Japan: Your Quickstart Guide.

You can find the form here on the National Tax Agency (NTA) site, and then use this page to find out which tax office to submit it to. Submission of the form can be in-person, via mail, or online. 

You’ll want to keep a copy of your kaigyou todoke in safekeeping, as it is often requested when opening a business bank account and completing other paperwork related to freelancing. 

2. Application for Approval of the Blue Tax Return [青色申告承認申請書]

The next form to fill out and submit along with your kaigyou todoke is an application called 青色申告承認申請書 = aoiro shinkoku shounin shinsei sho, which will allow you to submit the blue tax return. 

The blue tax return provides significant tax breaks for sole proprietors, so although this application is not mandatory, if you want to ease your upcoming tax bill, then consider this an essential step to that end.

The application form must be submitted by March 15 of the year in which you plan to file a blue tax return. If you start your business in the middle of the year, you can submit the form within two months of the start of your business.

The form is here on the NTA site, and you can send it in along with your kaigyo todoke to your local tax office.

3. Applying for National Pension [国民年金の手続き]

As an employee of a Japanese company, your company split the cost of your National Pension premium and deducted the pension sum from your salary. 

But now, as a freelancer/sole proprietor, you must apply and pay for national pension premiums for yourself within 14 days from the day after you leave your company.

You can apply to begin National Pension payments at the municipal office of the city or ward where you live. Make sure to bring your pension book or a 通知書 = tsuuchi sho that shows your pension number when you go to the city office.  

4. Applying for National Health Insurance [国民健康保険の手続き]

While it is possible to remain enrolled in your company’s health insurance for up to 2 years after you leave the company, most freelancers and sole proprietors opt against this option as the premiums will exceed what you used to pay. 

In almost all cases, freelancers will choose to enroll in 国民健康保険 = kokumin kenkou hoken, because all residents of Japan must be enrolled in the public health system.

You can apply for kokumin kenkou hoken at the municipal office of the city or ward where you live, and this should be done within 14 days after your last day at your previous company. 

Each city has a different rate for premiums, but all of them include a calculation that factors in income reported for the previous year. 

5. Applying for a Work Permit Outside of Your Current Visa Category [資格外活動許可申請]

For foreigners already residing in Japan, if you would like to work as a freelancer within the same field as your visa category, you can do so for the duration of your current visa without taking this step. 

However, if you want to work and earn money in a different visa category from the one specified on your visa, you will need to apply for a permit that will allow you to engage in activities other than what is specified on your current visa. 

For example, the 'Engineer/Specialist in Humanities/International Services' visa allows freelance-like work (e.g., IT, design, translation) if you can secure contracts that fit your permitted field. If you are on a Dependent or Student visa, you’ll need a 資格外活動許可 (Permission to Engage in Activity Other Than That Permitted by the Status of Residence Previously Granted) to freelance legally."

Visit the Immigration Services of Japan for more on the above-mentioned application, 資格外活動許可申請書 = shikakugai katsudou kyoka shinseisho.

To apply, fill out the application (available with English captions) and bring it along with your passport, residence card, and a document stating the activities in which you wish to engage to an immigration office. 

Think of it like a self-sponsor visa, where you will be in charge of your work.

Is there a freelance visa for Japan? 

For those outside of Japan who wish to get a freelance visa, there is currently no visa in Japan specifically labeled as a "freelance visa.” However, it is possible to work as a freelancer under certain existing visa types, depending on your field and immigration status.

📄 Visa types that allow freelancing in Japan

Some freelancers have also successfully applied for visa renewals or business manager visas using:

• Their Kaigyō Todoke (business opening form)

• Proof of tax payments

• Income documentation (invoices, bank transfers)

⚠️ Tip: Immigration policies can change, and individual eligibility varies. Always consult with an immigration lawyer or contact the Tokyo One-Stop Business Establishment Center (TOSBEC) for free multilingual support.

6. Further steps to consider as a freelancer in Japan 

While these next steps aren’t mandatory in Japan, the following business-savvy actions might be worth considering. 

a. A business address that isn’t your home address

Many freelancers start off by working from home, which keeps overhead low. However, one drawback to WFH is the necessity of listing an address on invoices and other business materials to prove legitimacy. If you want to avoid putting your home address on invoices or other business materials, we’d recommend using a virtual mailbox service that gives you a unique business address. This way you can check your physical business mail from your home and protect your private home address.

b. A dedicated business bank account 

Most accountants advise freelancers and sole proprietors to open a separate bank account for their business. This isn’t mandated and you won’t get directly penalized if you don’t have a dedicated business bank account. However, in order to streamline your accounting process, it is generally recommended that you separate your business and personal bank accounts. One solution here is to designate an existing personal bank account the one you use solely for business purposes. 

c. A dedicated business credit card

As a freelancer, your income will likely fluctuate from month to month. Therefore, many Japanese business sites recommend getting a credit card before leaving your current employment, as your income will look stable during the credit card check. Additionally, having a credit card that is dedicated to business-related items will be easier for you to sort through when doing accounting for your business. 

Cost breakdown for freelancing in Japan

The following costs assume you've left full-time employment and are no longer having social insurance premiums automatically deducted from your paycheck.

As a freelancer, you'll now handle all these payments directly and bear the full cost that was previously split with your employer.

Mandatory government fees

The paperwork itself costs very little, but the ongoing obligations add up quickly. Most filing fees are free, though some immigration applications require modest payments.

Monthly social insurance obligations

These represent your largest ongoing expenses as a freelancer in Japan and often come as a shock to new freelancers. As a full-time employee, your company paid roughly half of your social insurance costs and handled all the paperwork. Now you'll pay the complete amount yourself and manage all the administrative tasks.

National pension

The monthly contribution is ¥17,510 for fiscal year 2025, regardless of your income level. This fixed rate applies to all freelancers and sole proprietors between ages 20-59.

National health insurance

Health insurance premiums vary significantly by municipality and income. Each city calculates premiums using your previous year's earnings, household size, and local rates that are set annually. The calculation typically includes both a fixed component and an income-based component.

Premium amounts differ substantially between locations, making it essential to check your specific municipality's rates. Major cities generally have higher premiums than rural areas, but the exact calculation method varies by location. Contact your local city hall or check their website for precise premium calculations based on your situation.

First-year reality check

Your initial costs will be higher than ongoing expenses due to setup requirements and potential income transitions.

Immediate setup costs (first 3 months)

• National pension: ¥52,530 (3 months at ¥17,510/month)

• Health insurance: Variable based on municipality and previous income

• Business bank account opening: ¥1,000 - ¥3,000

Cost-saving strategies

• Pension discounts: Paying pension premiums annually in advance provides government discounts of around ¥3,000 for full-year prepayment.

• Health insurance optimization: Some freelancers can continue their company health insurance for up to two years, though premiums often increase. Compare your company's continuation rates against national health insurance before deciding.

• Business expense deductions: While not reducing insurance costs directly, proper business expense tracking can significantly lower your taxable income, which affects future health insurance calculations.

• Planning your transition: Budget for at least six months of insurance premiums before leaving employment. The combination of irregular freelance income and fixed monthly obligations requires careful cash flow planning, especially during your first year of operation.
