The Complete Guide to Choosing a Shared House—Comprehensive Explanation of Costs, Rules, and Trouble Prevention

What is a Shared House?

A shared house is a style of housing where multiple residents live in one building, share common spaces such as a kitchen, bathroom, and living room, while each resident uses their own private or semi-private room.

The biggest difference from a typical rental apartment is the lower initial costs and the formation of community. In urban areas like Tokyo and Osaka, a standard rental apartment might cost ¥300,000–¥500,000 in total for security deposit, key money, and agency fees combined, while shared houses typically allow you to move in for around ¥50,000–¥150,000, making them a popular choice when moving to a new city or changing jobs.

Shared House Cost Overview

Monthly Costs

Monthly shared house costs combine "rent" and "common service fees (maintenance fees)."

Most shared houses include common service fees that cover utilities, Wi-Fi, and consumables, so you rarely have to pay additional public utility charges.

Initial Costs

Typical breakdown of initial costs for a shared house:

• •Deposit (Security Deposit): 1–2 months' rent (returned upon move-out, minus any damage)
• •Rent for Move-in Month (Pro-rated)
• •Administrative Fee: 0–1 month's rent

Security deposits, key money, and agency fees are typically not required. Many shared houses also do not require a guarantor, making entry screening easier.

Key Points in Selecting a Property

1. Verify the Management Company's Credibility

The living environment of a shared house varies greatly depending on the management quality of the operating company. Points to verify:

• •Operating company's track record and reviews (check on Google, social media, and comparison sites)
• •Number of properties and years in operation (longer track records tend to be more stable)
• •Whether there is a trouble resolution desk during occupancy
• •Whether there is a 24-hour emergency contact

Major shared house operators (such as Oak House, Borderless House, and SAKURA HOUSE) typically have well-organized management systems.

2. Common Area Facilities and Cleanliness

Be sure to check the common areas during a viewing.

Facilities to Check:

• •Kitchen: number of stovetop burners, refrigerator storage space, and usability of dish storage
• •Bathroom: number of sinks and showers (adequate for the number of residents)
• •Washing Machines: number of machines and usage time rules
• •Living Room: size, condition of furniture, and speed of shared Wi-Fi

Cleanliness Check:

• •Kitchen stovetop and range hood cleanliness
• •Bathroom drain and mold condition
• •Toilet cleanliness
• •Trash area management

How well-maintained the cleanliness is reflects both the morality of current residents and the management company's response quality.

3. Private Room Size and Soundproofing

Private rooms in shared houses typically range from about 4 to 8 tatami mats in size. How to choose a private room:

• •Lockable Private Room: A lock is essential to protect privacy (avoid rooms without locks)
• •Floor Area: Considering your belongings, 4 tatami mats or larger is the minimum for livability
• •Soundproofing: Check that noise from adjacent rooms and corridors doesn't leak in (verify during viewing)
• •Window Position: Natural light, ventilation, and privacy from outside views

4. Resident Community and Atmosphere

In a shared house, the compatibility between residents affects quality of life.

• •International Shared Houses: Properties with many foreign residents, designed for English learning and international exchange. Examples include Borderless House and SAKURA HOUSE.
• •Women-Only Shared Houses: Properties for women that prioritize security
• •Themed Shared Houses: Residents with common hobbies or purposes gather, such as IT, creative professionals, or agriculture
• •Mixed-Gender Type: The most common type

During a viewing, check if you can talk with current residents, and if possible, say a quick hello. You can directly sense the atmosphere.

About Entry Screening

Entry screening for shared houses is often more lenient than for standard rentals, but you may be asked for the following:

• •Identity verification documents (including passport and residence card)
• •Proof of employment/income (employment certificate or pay stub)
• •Reason for moving and self-introduction

Many properties welcome foreign nationals, and screening may be approved even for the unemployed or freelancers. Many properties also do not require a guarantor.

Shared House Rules and Shared Living Etiquette

Common Rules

Each shared house has its own set of rules. Be sure to check these before moving in:

• •Quiet Hours Rules: Lights out time and common area usage hours
• •Visitor Rules: Rules regarding overnight guests such as friends or romantic partners (many properties do not allow overnight guests)
• •Common Kitchen Rules: Washing up after use and food storage methods
• •Washing Machine Usage Hours: Most properties prohibit late-night use
• •Garbage Disposal Rotation: Rules for rotating or shared responsibility

Common Troubles and Prevention Strategies

Noise and Living Sound Troubles:

• •Late-night use of common areas and loud voices
• •Footsteps and door opening/closing sounds

→ Prevention Strategies: Follow the property's rules and keep quiet at night. Use headphones or earbuds.

Kitchen and Common Space Usage Troubles:

• •Leaving dishes unwashed
• •Using shared seasonings without asking

→ Prevention Strategies: Always clean up after yourself. Develop a habit of replenishing shared items when they run low.

Personal Troubles Between Residents:

• •Food in the common refrigerator was mistaken for someone else's because it wasn't labeled with a name
• •Personal items were moved when a private room was left unlocked

→ Prevention Strategies: Always label your food in the common refrigerator with your name. Always keep your private room locked.

Properties with a House Manager (on-site manager) have quick trouble resolution, so on-site manager properties are recommended for first-time shared house residents.

• •Move-Out Notice Period: Standard notice is one month before move-out
• •Deposit Return: Returned after deducting damages and cleaning costs to the private room
