Introduction

Recently, more people are starting side jobs, and this includes Long-Term Resident status holders who work side jobs without changing their main workplace. However, during renewal of Long-Term Resident status, stable income and employment are crucial requirements, so many may worry how side income is treated. This article explains, using official government information, what to consider when providing income proof for status renewal applications when working a side job without changing the main job.

What is “Long-Term Resident”?

The “Long-Term Resident” status is a residency category authorized by the Immigration Services Agency of Japan. This status covers people such as refugees, descendants of Japanese nationals, or those deemed eligible for special residency, but it is not based strictly on familial status. Therefore, applicants undergo examinations on stability and ability to support themselves financially (see Ministry of Justice “About Long-Term Resident Status” ).

Impact of Side Income on Renewal

For the renewal of Long-Term Resident status, authorities focus on whether the applicant can continue stable living in Japan. Those maintaining their main job and earning side income will have both sources reviewed as part of their overall financial capacity. Government sources state that, for renewal applications, documents must be provided to prove both employment and income status, such as withholding statements, income certificates, and tax records (see Ministry of Justice’s “Status Renewal Procedures” ).

Points of Caution for Income Proof

When submitting documents to show side income, pay attention to the following:

• Prepare proof of continued employment at the main job (employment contracts, proof of employment)
• Report side income correctly and submit official documents, such as tax certificates or copies of filed tax returns
• Demonstrate that combined annual income supports stable living in Japan
• Confirm that side jobs do not violate laws or the scope of authorized work
• Tax office-issued income certificates are generally regarded as more credible than municipal certificates

Thus, even if you have not changed your main workplace, it’s essential to declare side income accurately to avoid negative outcomes in visa renewal .

Possible Scenarios in Screening

Even stable side income may not compensate for a sudden drop in main income or insufficient proof of income, which could lead to longer screening times or additional document requests. Also, officials will check whether the nature of the side job violates status of residence rules; for example, running a business as a side job or holding many jobs might require extra notifications or permits (see Immigration Services Agency “Regarding Activities Outside the Status of Residence” ).

Sample Case

For example, imagine a Long-Term Resident working as a full-time employee at a factory while taking a part-time job at a restaurant on weekends. In this case, submission of the job contract and pay slips for the factory, copies of tax returns for the side job, and an overall tax certificate showing combined income is advisable. Ensure your side job does not fall outside of your authorized activities.

Conclusion

Even when not changing your main job, renewal of Long-Term Resident status requires submission of accurate income proof. Use tax certificates and employment contracts to properly demonstrate your income and maintain transparency. Always check the latest requirements with official government websites and consult a professional if you are unsure.
