A comparison of dormitories, kaikan, share houses, and renting privately in Japan for international students. Updated costs, guarantor systems, and recommendations for good areas to live in August 2026.
When you arrive in Japan to study, alongside the excitement of finally realizing your dream, the biggest question troubling most new Vietnamese international students is: "Where should I live so that it’s affordable, safe, and not too restrictive?" With options ranging from school dormitories and student residences (kaikan) to share houses and private apartments, each type comes with its own rules and costs. Choosing the wrong accommodation during your first few days can place a heavy burden on your finances and directly affect your studies and part-time work. In this article, the OlaChill editorial team will analyze each option in detail, provide updated real-world prices (as of August 2026), and share practical advice to help you quickly settle down in the Land of the Rising Sun.
The housing "matrix" in Japan: the 4 most popular options for international students
For international students who have just arrived in Japan or are moving on to a new level of education, the current housing market can be divided into 4 main categories.
1. School dormitories (学生寮 - Gakuseiryo)
This is one of the safest options, managed and operated directly by Japanese-language schools, vocational schools (専門学校 - senmon gakko), or universities.
- Features: Rooms usually come furnished with basic essentials such as a bed, desk, refrigerator, and air conditioner. Depending on the school, you may stay in a single or shared room (2-4 people per room).
- Advantages: Low initial costs and simple procedures because the school acts as your guarantor. Dormitories are usually located near the campus, helping you save on transportation.
- Disadvantages: Less freedom because of curfews (門限 - mongen), strict rules about inviting friends over, and limited residence periods (typically only 6 months to a maximum of 1-2 years so that places can be made available for new students).
2. Student residences / Kaikan (学生会館 - Gakusei Kaikan)
Student residences are private dormitory-style facilities operated by companies specializing in student housing management, such as Kyoritsu Maintenance through its Dormy system.
- Features: Similar to school dormitories but more professionally managed. Many offer packages that include 2 meals (breakfast and dinner), with a building manager (寮長 - ryocho) living on-site.
- Advantages: Excellent security, clean shared facilities, and daily nutritional support without having to spend time cooking.
- Disadvantages: Overall rent is fairly high, meal charges are fixed in the contract whether or not you eat, and residents must still follow communal rules.
3. Share houses (シェアハウス)
Share houses have become extremely popular in major cities such as Tokyo and Osaka in recent years, with well-known operators including XROSS HOUSE and Oakhouse.
- Features: You have either a private bedroom (private room) or a bunk bed (dormitory), while sharing the kitchen, living room, toilets, and bathrooms.
- Advantages: Fully furnished, free internet, no complicated guarantor requirements, low initial costs, and flexible contracts (short-term rentals from 1-3 months).
- Disadvantages: Privacy in shared areas is limited, and conflicts may arise with housemates from different countries and with different lifestyles.
4. Renting a private apartment (アパート / マンション)
This involves renting a private 1R apartment (a very compact single room) or 1K apartment (one room + a separate kitchen) directly from a landlord through a real estate agency (不動産 - fudosan).
- Features: You have complete control over your living space.
- Advantages: Complete freedom regarding your schedule, the ability to invite friends over (within the rules), and total privacy.
- Disadvantages: Initial costs (初期費用 - shoki hiyo) are very high, rooms are completely unfurnished, screening procedures are strict, and you must have an individual or company guarantor.

| Contract period | 6 months – 1, 2 years | 1 – 2 years | Flexible (from 1 month onward) | Fixed at 2 years (early cancellation incurs a penalty) |
Understanding school and guarantor-company systems
The biggest challenge international students face when renting a private home on their own in Japan is finding a guarantor (保証人 - hoshonin). Japanese society places great importance on reliability; if a tenant disappears or fails to pay, the guarantor becomes responsible for the entire financial obligation.
School-based guarantor system (機関保証 - Kikan Hosho)
To support international students, many universities and vocational schools in Japan offer a collective guarantor system.
- How it works: The school acts as your joint guarantor (連帯保証人 - rentai hoshonin).
- Associated insurance: This is often combined with the Comprehensive Insurance for Foreign Students' Housing (留学生住宅総合補償 - Ryugakusei Jutaku Sogo Hosho) program, implemented by the Japan Student Services Organization (JASSO) in cooperation with the Japan Educational Exchanges and Services (JEES).
- Cost: JEES insurance premiums are relatively affordable. As of August 2026, they are approximately 4,000 JPY/1 year (~670,000 VNĐ) or 8,000 JPY/2 years (~1,340,000 VNĐ).
Renting through a guarantor company (保証会社 - Hoshon gaisha)
If your school does not offer a guarantor system, or the landlord does not accept a school as guarantor, you will generally need to rent through a professional financial guarantor company, such as GTN - Global Trust Networks, Nihon Safety, or Casa.
- Service fees: The initial registration fee is usually 50% to 100% of one month's rent (approximately 30,000 – 60,000 JPY). The annual maintenance fee is approximately 10,000 JPY/year.
- Japanese documents you must prepare:
- Residence card: 在留カード (zairyu card).
- Certificate of residence: 住民票 (juminhyo), obtained from the ward or city where you live.
- Student ID: 学生証 (gakuseisho) or Certificate of Admission (入学許可書 - nyugaku kyokasho).
- Bank account balance certificate: 預金残高証明書 (yokin zandaka shomeisho) or proof of part-time income / savings account.
- Emergency contact information (an emergency contact in Vietnam and one in Japan).
Balancing housing costs with part-time income (Baito)
Under the regulations of Japan’s Immigration Services Agency, international students holding a "Student" status of residence are permitted to work a maximum of 28 hours/week (28時間/週 - niju-hachi jikan / shu) during school terms, and 8 hours/day during official summer and winter holidays.
Realistic Baito income calculations (as of August 2026)
- Tokyo’s minimum hourly wage as of 2026 ranges from approximately 1,113 – 1,200 JPY/hour (night shifts from 22h-5h receive a 25% premium, bringing the rate to approximately ~1,400 - 1,500 JPY/hour).
- If you work the full 28 hours/week at an average wage of 1,150 JPY/hour: $$\text{Monthly income} = 28 \text{ hours/week} \times 4 \text{ weeks} \times 1,150 \text{ JPY} = 128,800 \text{ JPY/month} \quad (\approx 21.6 \text{ million VNĐ})$$
Principles for allocating your housing budget
Financial experts and senpai with real-world experience recommend that monthly housing costs (including rent + management fees 管理費 / 共益費) should never exceed 30% to 35% of your total monthly income.
- Safe housing budget for international students: Approximately 35,000 – 48,000 JPY/month (~5.8 – 8.0 million VNĐ).
- If your rent is 65,000 JPY, you will have only a little over 60,000 JPY left for tuition, food, transportation, national health insurance (国民健康保険 - kokumin kenko hoken), and your phone bill. The financial pressure will be extremely heavy!
Recommended affordable, international-student-friendly areas with large Vietnamese communities
Choosing your neighborhood wisely can help you save on rent while also making it convenient to commute and buy Vietnamese food.
1. The Tokyo metropolitan area
- Edogawa Ward (江戸川区) - Kasai Station (葛西) & Nishi-Kasai Station (西葛西): Often regarded as the "capital" of Vietnamese international students and young families. Rent for a 1K apartment here is only around 50,000 – 65,000 JPY/month, much lower than in central Tokyo. The area has many Vietnamese grocery stores, the affordable Gyomu Super (業務スーパー), and convenient access to Nihonbashi/Otemachi via the Tozai Line.
- Kita Ward (北区) - Akabane Station (赤羽) & Tabata Station (田端): Extremely convenient transportation, as these stations are on the Yamanote Line and Keihin-Tohoku Line. Rent is moderate (55,000 – 70,000 JPY/month), and the area has many lively local markets.
- Tobu Tojo Line (東武東上線) & Seibu Shinjuku Line (西武新宿線): Stations along these two lines, such as Kami-Itabashi, Narimasu, Nogata, and Tanashi, are only 15-25 minutes by train from Shinjuku/Ikebukuro, yet rents are extremely affordable, starting at just 40,000 – 55,000 JPY/month.
2. The Kansai area (Osaka)
- Yodogawa Ward (淀川区) - Juso Station (十三): An important transport hub connecting Osaka, Kyoto, and Kobe. Housing is affordable, with 1R/1K apartments costing only 35,000 – 50,000 JPY/month.
- Ikuno Ward (生野区) & Higashinari Ward (東成区): Areas with large Vietnamese and Asian communities. The cost of living is low, and there are many part-time jobs at restaurants and supermarkets.
3. The Tokai area (Nagoya / Aichi)
- Showa Ward (昭和区) & Chikusa Ward (千種区): Close to major universities such as Nagoya University and Nanzan University. Rents are highly student-friendly, at approximately 30,000 – 45,000 JPY/month.
Frequently asked questions
Q. Can I rent a private apartment on my own if I have just arrived in Japan and do not yet have a bank account or Japanese phone number?
Answer: It is very difficult. Most Japanese real estate companies require you to have a Japanese phone number (to receive verification calls) and a bank account (for automatic monthly rent payments - 口座振替 kokusa furitake). Therefore, the best solution for your first 3-6 months in Japan is to stay in a School dormitory or Share house. Once you have received your Residence Card, opened a Yucho Bank account (ゆうちょ銀行), and obtained a phone SIM, you can consider moving out and renting a private apartment.
Q. What is the difference between key money 礼金 (reikin) and a security deposit 敷金 (shikikin), and can they be refunded?
Answer:
- Security deposit 敷金 (shikikin): This is money you pay to the landlord as a deposit (usually equal to 1 month's rent) to cover unpaid rent or damage to the room. When you move out, the landlord will deduct professional cleaning costs (クリーニング代 - kuringu dai) and repair costs for any damage. The remaining amount will be refunded to you.
- Key money 礼金 (reikin): This is a "thank-you" payment given to the landlord for renting you the room. This amount is completely non-refundable. Today (August 2026), many apartments offer "0 Reikin" (礼金ゼロ) policies to attract international students, so you should prioritize looking for these properties.
Q. If I cancel my rental contract before the 2-year term ends, will I be penalized?
Answer: Yes. Most private rental contracts (アパート) in Japan run for 2 years and include an early cancellation penalty clause (cancellation before 1 year). The penalty is usually equivalent to 1 to 2 months' rent. If you plan to stay for less than 1 year or are about to graduate and return home, consider choosing a Share house or looking for apartments that explicitly state "No penalty for short-term cancellation."
Q. Can an international student secretly move a roommate into a self-rented 1R/1K apartment?
Answer: Absolutely not! This is strictly prohibited. Japanese rental contracts clearly specify the permitted number of residents (typically, a 1R/1K apartment allows only 1 person). If the landlord or management company discovers that someone is living there without authorization, it will be considered a serious breach of contract (契約違反 - keiyaku ihan). This could result in unilateral termination of your contract, a requirement to pay compensation, and potential effects on your residence history when renewing your student visa.
Conclusion
The right type of housing for studying in Japan depends entirely on your financial situation, personality, and stage of life. If you have just arrived, are unfamiliar with Japanese, and are still finding your feet, a School dormitory or Share house can be a "lifeline" that reduces your initial financial pressure and helps you integrate quickly. Once you have been settled for 1 year or more, have a steady baito income, and feel confident communicating, moving into a private apartment will give you complete freedom and privacy.
