Preparing for a Part-Time Job in Japan: Essential Checklist

Most people who study or go on a Working Holiday in Japan end up working a part-time job (baito). However, when you actually try to apply, you might realize, "I should have prepared this in advance." Here is a checklist of things you should have ready before you start applying.

Essential checklist for starting a part-time job in Japan: phone number, residence card, bank account

What You Need at the Application Stage

1. A reachable Japanese phone number
Part-time job applications always have a contact information section, and employers will use this number to schedule interviews or notify you of hiring decisions. If you write a foreign number, communication won't be smooth, which can put you at a disadvantage. It is best to have a Japanese number ready before applying.

2. Residence Card (Zairyu Card)
To work a part-time job, your visa status must be verified. If you are on a student visa, you must obtain Permission to Engage in Activity Other Than That Permitted Under the Status of Residence Previously Granted (working without this permission can lead to serious legal issues).

3. A Japanese bank account
You need a Japanese bank account to receive your salary. And to open a bank account, you will need the Japanese phone number mentioned above.

Why the Order of Preparation Matters

These three items are closely interconnected.

  • To open a bank account → You need a phone number
  • To receive your salary → You need a bank account
  • To receive application and interview calls → You need a phone number

In other words, a phone number is the starting point for everything. Trying to find a job without a number will lead to constant roadblocks right from the application stage. If you want to start working quickly after arriving, securing a phone number first is the most logical step.

Don't Forget the Work Permit (Permission for Other Activities)

To work on a student visa, you must obtain permission to engage in other activities either upon entry or afterward. You can apply for this at airport immigration during entry, or later at a local Immigration Services Bureau. Working beyond the permitted hours (e.g., the weekly limit) can negatively impact your visa status, so it is crucial to understand the conditions and work strictly within those limits.

(Since specific regulations may change over time, please check official government guidelines for the latest information.)

Summary of the Preparation Steps

  1. Secure a Japanese phone number — Ideally before leaving your home country
  2. Residence Card & Work Permit — Complete the procedures upon arrival
  3. Open a bank account — After setting up your phone number
  4. Apply for part-time jobs — Once the top three are ready, applications and payroll will go smoothly
