Finding Part-Time Work on a Student Visa in Japan

To work part-time in Japan on a student visa, you must obtain the 'Shikakugai Katsudo' permit, which allows you to work up to 28 hours per week during the semester. This permission is typically granted at the airport upon arrival or via a later application at a regional immigration bureau. Once approved, you can explore a wide range of 'arubaito' (part-time jobs) to support your studies and travel expenses. \n\n## Understanding the Shikakugai Katsudo Permit \n\nThe 'Permission to Engage in Activity Other Than That Permitted Under the Status of Residence Previously Granted' is the legal bridge between being a full-time student and a part-time worker. Without this stamp on the back of your Residence Card (Zairyu Card), any form of employment—even unpaid internships in some cases—is strictly prohibited. \n\n### How to Apply \n\nThe most efficient way to get this permit is at the 'Landing Examination' counter when you first arrive at major airports like Narita, Haneda, Kansai, or Chubu. You simply present a small application form along with your Certificate of Eligibility (COE) and passport. If you miss this opportunity, you must visit a regional immigration office, which can take several weeks to process. Having immediate data access upon landing is crucial for downloading these forms or checking instructions; using a StudyRoam eSIM ensures you are connected the moment you touch down. \n\n### The 28-Hour Rule \n\nThe Japanese government is strict about the 28-hour weekly limit. This limit applies across all jobs combined. If you work two jobs, the total hours must not exceed 28. During long academic breaks (summer, winter, and spring vacations), this limit is usually extended to 40 hours per week (8 hours per day). Exceeding these hours can lead to the revocation of your visa or denial of your visa renewal. \n\n## Popular Student Visa Jobs in Japan \n\nFinding work in Japan depends heavily on your Japanese language proficiency. However, there are roles for every level. \n\n* Convenience Stores (Conbini): 7-Eleven, Lawson, and FamilyMart are always hiring. These roles require at least N3 level Japanese as you will handle cash and customer service. \n* Restaurants and Izakayas: Working in the 'kitchen' (chubo) is great for those with lower Japanese levels, while 'hall' (horu) staff need better speaking skills. \n* English Teaching: Many students find work in Eikaiwa (English conversation schools) or as private tutors. This is often the highest-paying part-time work available. \n* Hotel and Hospitality: In tourist hubs like Kyoto or Niseko, hotels often hire English-speaking students for front desk or cleaning roles. \n\nFor more general advice on working while abroad, check out our guide on How to Find Part-Time Student Jobs While Studying Abroad. \n\n## The Connectivity Gap: Why You Need an eSIM \n\nOne of the biggest hurdles for international students in Japan is the 'connectivity loop.' To get a local Japanese phone contract, you usually need a Japanese bank account. To get a Japanese bank account, you need a local phone number. This can leave students without data for weeks while they navigate the bureaucracy. \n\nStudyRoam provides a solution by offering data-only eSIMs that work immediately. While these plans do not include a local +81 phone number, they allow you to use WhatsApp, Line (essential in Japan), and Google Maps to navigate to interviews and immigration offices. You can see plans that cover your first month or even your entire first semester. \n\n### Coverage Realities: Cities vs. Rural \n\nJapan enjoys some of the best mobile infrastructure in the world. StudyRoam plans utilize all four major national carriers: NTT docomo (5G), Rakuten Mobile (5G), KDDI/au (5G), and SoftBank (5G). \n\n* Tokyo, Osaka, Nagoya: You will have near-constant 5G coverage. Rakuten and SoftBank are particularly strong in high-density urban areas. \n* Rural Areas (Hokkaido, Japanese Alps): NTT docomo and KDDI/au have the most extensive reach in mountainous regions and smaller villages. \n\n### Choosing the Right Data Plan \n\nDepending on your needs, you can choose between fixed data amounts or daily passes. If you are using your phone for heavy navigation and video calls back home, the 20GB/30 days or 50GB/30 days plans are popular for the first month. For those on shorter exchange programs, the 50GB/180 days plan offers a long-term 'safety net' of data. \n\n| Feature | Local Carrier Contract | Pocket WiFi Rental | StudyRoam eSIM | \n| :--- | :--- | :--- | :--- | \n| Contract Length | 12-24 Months | Daily/Weekly | Flexible (7-180 days) | \n| Bank Account Needed | Yes | No | No | \n| Hardware | Physical SIM | External Device | Digital (eSIM) | \n| Network | Single | Single | Multi-network (Docomo/SoftBank/KDDI/Rakuten) | \n\n## Step-by-Step eSIM Installation \n\nBefore you leave for Japan, you should check if your phone is compatible with eSIM technology. Most iPhones (XR and newer) and modern Android devices support it. \n\n### On iPhone \n1. Go to Settings > Cellular. \n2. Tap Add eSIM. \n3. Scan the QR code provided by StudyRoam. \n4.

This includes bars where staff sit with customers, host clubs, pachinko parlors, and even some types of game centers or internet cafes that are classified under these laws. Even working as a cleaner in a pachinko parlor is a violation of your visa terms. Always clarify the business type before accepting a job. \n\n## The bottom line \n\nSecuring a part-time job in Japan is a fantastic way to immerse yourself in the culture and offset living costs. By getting your Shikakugai Katsudo permit at the airport and securing a see plans data package from StudyRoam, you'll have the legal right and the digital tools to start your job hunt the moment you arrive.
