In short
- A regular Japanese apartment charges 4 to 6 months of rent up front (around 200,000 to 300,000 yen). For a new arrival, that is brutal.
- A share house skips the deposit, key money, and guarantor requirement – move-in cost is often under 100,000 yen, furnished, with internet included.
- The largest operator is Oakhouse – over 20 years running, with strong support for foreign residents.
- You end up living alongside both foreign and Japanese residents, which makes friends and Japanese practice happen naturally.
- It is not for everyone: if you want total quiet and privacy, look for a private-room plan first.
Finding a room in Japan is expensive before you even move in
Housing is usually the first wall a new arrival hits. A standard Japanese apartment charges move-in costs (deposit, key money, agency fee) worth 4 to 6 months of rent. On top of that, most landlords want a Japanese guarantor, and you still have to buy your own furniture and appliances. For someone who just landed in the country, this is a genuinely heavy burden.
The fix: a share house, with move-in costs on a different scale
A share house is a building where residents share the kitchen, living room, and bathroom, while each person has their own bedroom (private or shared). The single biggest advantage is the move-in cost.
Beyond the move-in cost, a share house solves several problems new arrivals commonly run into all at once.
Oakhouse: the operator most students end up choosing
Oakhouse is one of the largest share house operators in Japan, running for over 20 years, with a strong track record hosting foreign residents. Here is what stands out:
- No deposit, no key money, no guarantor: many properties let you move in for under 100,000 yen total
- Furniture, appliances, and internet included: you can start living, and job hunting, the day you arrive
- Social residences: some larger buildings include a gym, lounge, or theater room – amenities you would never get living alone
- International events: foreign and Japanese residents mix naturally, which is where friendships and Japanese language practice tend to start
Who it fits, and who should think twice
A share house is not the right fit for everyone. Check yourself honestly against this table before you commit.
| Good fit | Think twice if you… |
|---|---|
| Want to keep move-in costs low | Want total silence and full privacy |
| Do not have a guarantor | Dislike sharing a kitchen or bathroom |
| Just arrived with no furniture | Keep unusual hours (late-night work, for example) |
| Want to meet people and make friends | Find shared cleaning and trash rules annoying |
If you like the idea of community but still want your own space, look for a private, lockable room plan – you get the shared common areas without giving up a quiet room to retreat to. Popular properties fill up quickly, so if a listing catches your eye, check it sooner rather than later.
In Tokyo, X-House is another strong option
Oakhouse covers all of Japan and leans toward community living in larger houses. X-House focuses on Tokyo and Osaka with “shared apartments” where every room has its own lock, closer to a private studio with shared building costs.

Frequently asked questions
Q. Can I really move in without a guarantor?
Yes. Most share house operators, including Oakhouse, do not require a Japanese guarantor. This is a major advantage for a new arrival who does not know many people in Japan yet.
Q. Is the move-in cost really under 100,000 yen?
It depends on the property and plan, but because there is no deposit or key money and the room comes furnished, share houses are far cheaper to move into than a standard apartment (4 to 6 months of rent). Check the current price on the official site before you commit.
Q. Are there private rooms, or only shared rooms?
Both exist. There are lockable private rooms and cheaper shared dormitory-style rooms. If privacy matters to you, choose a private room plan.
Q. Is it okay if my Japanese is not strong?
Many properties have a large foreign resident base and English-language support, and some, like X-House, offer phone support in Nepali and Sinhala. Living alongside other residents also becomes informal language practice.
Q. What about contract length and moving out early?
Share houses typically allow shorter contracts than a standard apartment lease and more flexibility to move out, which suits short-term study or working holiday plans. Confirm the exact terms with each property.
