A 2026 guide to part-time jobs in Japan for Vietnamese international students: the 28-hour/week rule, pay at konbini/izakaya/supermarkets, Baitoru/Townwork/Hello Work apps, and Japanese interview tips.
Part-time work (arubaito / baito / アルバイト) is how most Vietnamese international students cover their living expenses in Japan. The law allows up to 28 hours/week during the school term and 40 hours/week during school holidays—enough to earn 80,000-120,000 yen/month. This guide covers everything from applying for permission and finding a job to interviewing in Japanese as a beginner.
Part-Time Work Permit — Apply at the Airport
A student visa does NOT automatically allow you to work part-time. You must apply for "Permission to Engage in Activity Other Than That Permitted Under the Status of Residence Previously Granted" (資格外活動許可 — shikakugai katsudo kyoka):
- Best time to apply: at the immigration counter at the airport when you first enter Japan. The immigration desk provides the form free of charge; tick "Yes" and they will stamp your residence card (zairyū card) on the spot
- If you forget at the airport: apply at your local immigration office (nyukan) instead—it takes 1-4 weeks to process, and during that time you are NOT allowed to work; working illegally can lead to deportation
- Fee: free
Once you have the permission, the back of your residence card will state "許可 (週28時間以内・風俗営業等の従事を除く)"—meaning "permitted for under 28 hours/week, excluding work in the adult-entertainment industry."
The 28-Hour Rule — Violations Can Lead to Deportation
This is a hard-and-fast rule. Nyukan checks through 2 sources:
- Employer tax reports: every year, employers submit 源泉徴収票 (gensenchoshuhyo) to the tax authorities. If your total income exceeds ~1,2 million yen/year, the system automatically flags it
- Bank records: regular salary deposits of >100k yen/month may be checked
Penalties if you are caught:
- Your visa extension may be denied, meaning you must return to Vietnam within 30 days
- In serious cases, you may be blacklisted and banned from returning to Japan for 5-10 years
How to correctly calculate the 28 hours:
- The week runs from Monday morning through Sunday night
- Add up ALL jobs combined (hours from 2 jobs are cumulative)
- Breaks between shifts (15-30 minutes) do not count
- During long school holidays (summer in August, winter in December-January, spring in March), you may work 40 hours/week
⚠️ Warning: Many Vietnamese izakaya owners hire international students for 50-60 hours/week and pay them in cash without reporting the income. Don't be tempted by the higher pay—getting caught even once can cost you your visa.

5 Best Ways to Find a Job
1. Baitoru (バイトル) — The No. 1 App
- Link: baitoru.com
- Japan's largest platform, with 500k+ jobs available at any time
- Use the "Gaikokujin kangei" (歓迎外国人) filter to find employers welcoming foreign workers
- An English version of the app is available, but the Japanese UI is easier to use
2. Townwork
- Link: townwork.net
- Focuses on jobs by area, making it easy to find work near home
- Free paper copies are available at train stations—pick one up to read while waiting
3. Hello Work (ハローワーク)
- Free government employment service
- Each ward has 1 office, usually near the kuyakusho
- Advisors can help you find jobs suitable for a student visa
- Jobs tend to be higher quality than those on apps, with stricter screening
4. Vietnamese Facebook / Zalo Communities
- Groups such as "Part-Time Jobs in Tokyo/Osaka/...": 50k+ members per group
- Advantages: you can ask specific questions, and many Vietnamese-owned businesses are hiring
- Downside: some employers pay cash without reporting income, putting your visa at risk
5. Friends from Home / School Senpai
- Getting a referral from a classmate is the easiest method for Vietnamese students
- Konbini and izakaya often already have 2-3 Vietnamese employees; once they refer you, you may be hired immediately
- If your school has a "notice board" in the student area, check it for job listings
Applying + Interviewing in Japanese
Calling to Schedule an Interview
Many employers want you to call first rather than apply online. Sample phrase:
もしもし、(バイトル)を見て、お電話しました。ベトナム人留学生の(NGUYEN)と申します。アルバイトの面接をお願いしたいのですが… (Moshimoshi, Baitoru o mite, odenwa shimashita. Betonamu-jin ryugakusei no Nguyen to moshimasu. Arubaito no mensetsu o onegai shitai no desu ga…)
Translation: Hello, I'm calling because I saw your listing on Baitoru. My name is Nguyen, and I'm a Vietnamese international student. I would like to request an interview for the part-time position…
Preparing a rirekisho (履歴書) — Japanese CV
- Buy a CV template at a konbini (~200 yen for 3 sheets)
- Or download a PDF from rirekisho.com and print it
- Attach a 4x3cm photo in the upper-right corner (wear a white shirt and use a white background)
- Write by hand in black ink, with neat handwriting (this is very important in Japan)
The Interview — Common Questions
| Question | Sample answer |
|---|---|
| 自己紹介お願いします (please introduce yourself) | 私はNguyenと申します。ベトナムから来た留学生です。(校名)で日本語を勉強しています。 |
| どうしてこの仕事を選びましたか? | 日本語を使いながら、日本文化を学びたいからです。 |
| 週何時間働けますか? | 平日は1日3-4時間、週末は8時間働けます。週28時間以内です。 |
| いつから始められますか? | 来週の月曜日から可能です。 |
| 何か質問はありますか? | 時給とシフトの詳細について教えていただけますか? |
After the Interview
- Employers usually call back within 2-3 days to inform you of the result
- If you are hired, they will send you an 雇用契約書 (koyo keiyakusho — employment contract). Read it carefully: pay, hours, shifts, and store address
- Important: keep a copy of the contract—when you extend your visa, nyukan may require proof of employment
5 Tips to Avoid Exploitation
- Pay below the minimum wage = illegal: report it to Hello Work (Labor Standards Office); they will investigate and penalize the employer
- No contract: cash-in-hand work makes it easy for employers to withhold your pay. Request 1 "kyūryō meisai" (給料明細 — payslip) every month
- Training must be paid: Japanese law is clear—training during the first 3-7 days must still be paid at ≥90% of the regular wage
- Overtime (zangyō) +25% after 40h/week, night shifts (22h-5h) +25%, holidays +35%. If your employer refuses to pay, take screenshots of your messages and report them to Labor Standards
- Work-related illness or injury = the employer must pay (rōsai hoken — workers' accident insurance). Don't pay for medication yourself
Managing Your Pay + Taxes
- Employers pay by bank transfer every month (on the 15th or 25th). Yuucho/Shinsei/Rakuten accounts are all accepted. See how to open a Yuucho account
- Income below 1,030,000 yen/year = exempt from income tax (shotokuzei). Most international students working 28h/week fall within this range
- However, you still need to pay Kokumin Kenko Hoken national health insurance (~1,500-3,000 yen/month depending on the region)
- When you return to Vietnam, remember to apply for a nenkin refund (年金脱退一時金)—see how to reclaim your nenkin
Summary
International students in Japan may work 28 hours/week (40 hours during school holidays) and earn 1,100-1,600 yen/hour depending on the industry—around ~80-120k yen/month, enough to live on and save some money. Apply for your permit at the airport, search through Baitoru/Townwork/Hello Work, and prepare a handwritten rirekisho and Japanese interview at the N3-N4 level. Don't work illegally or exceed 28 hours—you could lose your visa.
Preparing to move to Japan? Order a Japan eSIM before your flight so you have internet access as soon as you arrive—and can easily call employers to confirm interview schedules. Want to visit Tokyo, Osaka, and Kyoto during your break? A 7-day JR Pass is much cheaper than buying individual tickets.
