Questions to Ask at Every Viewing (Japan Rental Checklist)

Most rental regrets come from things you could have checked during the viewing.

Photos don’t reveal:

  • the neighbor’s bass at midnight
  • the mold smell in the closet
  • weak water pressure
  • phone signal dead zones
  • “it’s 7 minutes” that feels like 14 minutes uphill

This guide gives you a practical viewing checklist and the exact questions to ask so you don’t get talked into a bad fit.

Info byte: In Japan, real estate brokers are legally required to provide and explain “Important Matters” before the contract is concluded (they must hand you a document and explain it). This is part of the Real Estate Brokerage Act (Article 35). [^1]

1) Before you even enter the apartment (30 seconds that saves you hours)

Most people walk inside and start imagining furniture.

Do the opposite first.
Stand outside the building and scan for friction.

Ask yourself:

Is this area calm or chaotic?
Is the street narrow and loud?
Does it feel safe at night?

Then do the simplest move:
Walk 20–50 meters in each direction.

You’re checking if you’re next to:

  • a busy road
  • bars and late-night foot traffic
  • a school zone (loud mornings)
  • delivery noise (early mornings)

This is “free information” you only get in person.

2) Inside the apartment: the 7 checks that matter most

When you step in, your brain will focus on “pretty.”
You need to focus on “livable.”

AllKeep’s housing guide lists a few of the most practical checks renters should do during viewings: sunlight/ventilation, water pressure, phone signal, storage, and nearby facilities. [^2]

1) Sunlight + ventilation

Open windows. Look for airflow and listen for outside noise. [^2]

Even a “nice” apartment can become miserable if it’s dark, damp, and stagnant.

2) Water pressure (seriously)

Turn on taps. Flush the toilet. Old buildings can have weak pressure. [^2]

This is not a luxury check. It affects daily life.

3) Phone signal + internet reality

Concrete buildings can block signal. Test your phone in the main room. [^2]

If you work from home, ask where the router line will come in and whether fiber is available.

4) Storage (don’t assume)

Japanese apartments are small. Storage decides if your home feels clean or permanently messy. [^2]

Open every closet. Check depth. Look for awkward shapes.

5) Smell check

Open the closet. Open the bathroom. Smell for mold or stale humidity.

If it smells “damp,” you will fight it forever.

6) Noise check

Stand still for 10 seconds.
Listen for:

  • trains
  • traffic
  • neighbors
  • hallway doors

7) Layout reality

If you can’t place:

  • a bed
  • a desk
  • a small storage shelf

Then the apartment is not actually “your size,” even if it’s technically okay on paper.

3) Building checks (the stuff people forget until move-in)

The apartment unit can be fine, but the building can ruin your routine.

Ask these on-site:

  • Where is the garbage area? Is it clean or chaotic?
  • Is there bike parking? (Tokyo life becomes easier with a bicycle.)
  • Is there an elevator? If yes, does it feel small and slow?
  • Does the entrance feel secure and maintained?

You’re not judging aesthetics.
You’re judging whether the building is managed like adults live there.

4) The 12 questions to ask the agent (copy/paste script)

Here’s the viewing script that catches most problems.

The “daily life” questions

  1. “Which direction do the main windows face?”
  2. “Any noise complaints in this building?”
  3. “Is this unit known to have humidity/mold issues?”
  4. “What’s the mobile signal like here?” (you should test it too) [^2]
  5. “What are the garbage rules for this building?”

The “money” questions

  1. “What is the full move-in cost breakdown?”
    Ask for the total, itemized. No surprises.

  2. “Is there a cleaning fee at move-out written into the contract?”
    Move-out fees are common, and what matters is what’s written. [^3]

  3. “Is there a renewal fee? How much?”
    Renewal fees are a real thing in many contracts. MLIT’s rental terms guide explains that renewal fees may be specified as a special term and that contracts are normally 2 years. [^4]

The “contract friction” questions

  1. “Is this a fixed-term lease or a normal lease?”
    Fixed-term can change renewal expectations.

  2. “How much notice is required to move out?”
    MLIT’s apartment search guidebook notes termination notice is typically 1–2 months in advance (check the contract). [^5]

  3. “Do I need a guarantor company? What is the fee?”
    MLIT notes guarantee fees are often 35% to 50% of one month’s rent paid in advance for 2 years (not insurance). [^5]

  4. “Are co-occupants allowed? Any restrictions?”
    MLIT warns that if co-occupants aren’t stated during contract formation and you allow them without permission, you could be evicted. [^5]

5) Red flags (walk away signs)

Some issues are “trade-offs.”
Some are “this will cost you later.”

Red flags you should treat seriously:

  • The agent won’t clearly explain fees or avoids itemizing them
  • The apartment smells damp or moldy
  • Weak water pressure (you tested it)
  • Noisy street + thin windows
  • Storage is unusable
  • The building’s garbage area is chaotic and dirty (signals poor management)
  • The agent pressures you with “someone else is applying now” without clarity

You’re not being picky.
You’re protecting your future self.

6) The viewing checklist (simple + reusable)

Inside the unit

  • Sunlight + ventilation (windows opened) [^2]
  • Water pressure tested (tap + toilet) [^2]
  • Phone signal tested [^2]
  • Closet storage inspected [^2]
  • Smell check (closet + bathroom)
  • Noise check (10 seconds of silence)
  • Layout reality (bed/desk placement)

Building + area

  • Garbage area location + cleanliness
  • Bike parking
  • Security (lock/entrance feel)
  • Station route walked once

Contract questions

  • Move-out notice period confirmed [^5]
  • Renewal fee confirmed [^4]
  • Guarantee company fee confirmed [^5]
  • Co-occupant rules confirmed [^5]
