Ways to settle in Japan
There are currently two main ways to settle in Japan that Vietnamese people can choose from, each with different requirements and benefits.
Permanent Residency
Applying for a permanent resident visa (永住権) is one of the most popular ways to settle in Japan. With a permanent resident visa, you can live and work in Japan indefinitely without having to renew your visa. However, you still retain your Vietnamese nationality.
To qualify for permanent residency, you must have lived in Japan continuously for at least five years on a long-term visa (such as an engineer visa or a student visa that has been converted to a working visa). You must also demonstrate a stable income, obey the law, have no criminal record, and pay taxes.

Advantages of permanent visa:
- Freedom to change jobs and professions
- No corporate sponsor required
- Can be absent from Japan for longer periods (up to 5 years)
- Easy to borrow money from bank, buy house
Obtain Japanese citizenship
Obtaining Japanese nationality (帰化) is a way to settle in Japan completely, you will become a Japanese citizen with full rights and obligations like a native.
To obtain citizenship, in addition to the criteria of living time (usually 5–10 years), you must also prove your ability to speak Japanese, respect for history, traditions, and compliance with Japanese laws. The process often takes time and requires the support of legal services or lawyers.

When acquiring Japanese nationality, citizens will have basic rights such as:
- Have the right to vote and run for office
- Enjoy full social welfare policies
- Travel with Japanese passport (visa-free for many countries)
- Children automatically have Japanese nationality if born in Japan.
Prepare documents for settlement in Japan
Preparing documents is the most important step in the process of implementing settlement methods in Japan. Each type of settlement has different document requirements.
Permanent residency application
To prepare permanent residency application in Japan, you need:
- Original and copy of residence card from entering Japan to present.
- 4x3cm ID photo taken within 3 months.
- Proof of income and tax return.
- Proof of income of the guarantor in Japan.
- Educational certificates, degrees, employment contracts or business licenses if self-employed.
- Certificate of no criminal record or declaration of no violation of the law.
- Financial and housing statements if you have assets in Japan.
Permanent residency applications must be submitted to the Immigration Department where you are residing. A mandatory condition is that you have a sponsor with a stable income and sufficient financial capacity. The application review period usually lasts from 6 to 8 months, and may be longer depending on the case. A few applications are expedited within 3–4 months, but this is quite rare. Therefore, you should prepare your application completely and accurately from the beginning to avoid having to supplement it many times.
Naturalization application
The application for naturalization requires higher requirements, including:
- Handwritten application for naturalization in Japanese or English.
- Application for naturalization.
- 5x5cm ID photo taken within 3 months.
- Detailed personal history, work and length of stay in Japan.
- Certificate of Japanese Language Proficiency.
- All documents proving income and assets
- Certificate of no tax debt
- Criminal record certificate from countries of residence
Applications for Japanese nationality are submitted directly to the Ministry of Justice. The processing time is usually quite long, on average about 1 year from the date of application. In some special cases, this process can last up to 2 years. Therefore, you need to be patient and carefully prepare the required documents to avoid delays.
Regulations on immigration time in Japan
Once you have been granted permanent residency in Japan, you can live and work permanently without any time restrictions like regular visas. However, it is important to note that permanent residency must be renewed periodically, usually every 7 years. Permanent residents also enjoy many of the same rights as Japanese citizens, and in case of law violations, they will not be deported like temporary residents.

Answers to frequently asked questions about settling in Japan
