Contact UsWhat Is a Monthly Mansion?
A monthly mansion is a short-term furnished rental where all furniture and appliances are already set up, available from a minimum of one month. There are no initial costs such as security deposits, key money, or agency fees, and the entire contract process can be completed online.
Like a hotel, you can move in right away with minimal hassle — but unlike a hotel, you have a kitchen and washing machine, so you can cook and do laundry freely. With no long-term contract or guarantor required, it's ideal for anyone who needs housing for a fixed period such as a job transfer, training, or temporary stay.

3 Key Features of Monthly Mansions
01
Move In Immediately — Furniture Included
Everything from a bed and washing machine to a refrigerator and microwave is already in place. Just bring a suitcase and you're ready — moving costs are minimal.
02
No Deposit, Key Money, or Agency Fees
Skip the upfront costs that can run ¥300,000 or more with a regular lease. You only pay the monthly fee and a cleaning fee (approx. ¥10,000–¥20,000) on departure.
03
Available from Just 1 Month
Perfect for short stays: job transfers, training programs, temporary housing, or trial cohabitation. No need to worry about early-termination penalties like with a standard rental.

Staying for a Few Months on a Transfer or Training
Great for company-mandated transfers or short training programs where the stay length is fixed. Set your contract period in advance for a smooth, stress-free departure.
02
Temporary Housing While You Find Your Next Home
Many people use monthly mansions as a bridge while house-hunting, renovating, or waiting for a sale. No need to bring furniture — you can move light.
03
Starting a New Chapter Without the Baggage
If you're moving to a new city for work or study and want to try out the area before committing, a monthly mansion is ideal. Stay longer if you love it — or move on quickly if you don't.
FAQ
- How is it different from a hotel?
- A monthly mansion is a standard residential property rented on a monthly basis. You have access to a kitchen and washing machine, so you can cook and do laundry freely and keep costs down. Because hotels charge per night, stays of a month or more are almost always cheaper in a monthly mansion.
- Is it more expensive than a regular rental?
- The monthly rate may look higher at first glance, but there are no initial fees — no deposit, key money, agency fees, or furniture to buy. For stays of a few months or less, the total cost is often lower than a standard rental.
- What is the minimum stay?
- At Sumyca, the standard minimum stay is 1 month (30 days). Feel free to contact us with your preferred dates.
- Is there an application screening process?
- Yes, a simple screening with ID verification is required. Unlike standard rentals, you generally don't need a guarantor or proof of income. Non-Japanese residents are also welcome to apply.
