Japan Property Viewing Tips for Foreign Buyers: The Complete Naiken Guide

Buying property in Japan is one of the most exciting steps you can take as a foreigner living in or relocating to the country. But before you sign any contracts, the property viewing — called naiken (内見) or nairan (内覧) in Japanese — is your most critical opportunity to assess whether a property truly meets your needs. Unlike simply browsing online listings, an in-person viewing reveals the details that photos can never capture: natural light, neighborhood noise, structural condition, and the feel of day-to-day life in that location.

This guide walks you through everything you need to know about property viewings in Japan as a foreign buyer: how to prepare, what to look for, how to evaluate buildings, and how to navigate the process with confidence — even if your Japanese is limited.

What Is Naiken and How Do Property Viewings Work in Japan?

Naiken (内見) literally means "interior viewing." In Japan, all property viewings are arranged through a real estate agency (fudousan-ya). You cannot simply show up at a property and ask to look inside — appointments must be confirmed in advance through the listing agent, who will typically accompany you to the property.

For occupied homes or apartments, viewings are scheduled around the current resident's schedule, so flexibility is helpful. For vacant properties, agents often have keys and can arrange viewings more quickly.

Key things to understand about Japanese property viewings:

• Shoes off: Always remove your shoes at the entrance (genkan). This is a firm cultural rule.
• Punctuality matters: Arriving on time (or a few minutes early) is expected and respectful.
• Ask permission before touching: Don't open drawers, closets, or appliances without asking the agent first.
• Photography: Always request permission before taking photos or videos.
• Multiple viewings are acceptable: It is entirely normal to visit a property 2-3 times under different conditions (morning vs. afternoon, weekday vs. weekend).

Essential Items to Bring to Every Property Viewing

Professional property hunters in Japan recommend coming to every naiken well-prepared. Here is what you should bring:

A compass app is especially useful: checking which direction the windows face tells you how much direct sunlight the rooms will receive in the morning and afternoon — something online listings rarely specify accurately.

Structural and Safety Checks: What Every Foreign Buyer Must Verify

Earthquake Safety Standards

Japan's seismic safety laws divide buildings into two categories:

• Old seismic standard (旧耐震基準): Buildings with construction approval before June 1981. These were designed to prevent collapse in a moderate earthquake but carry significantly higher collapse risk in major earthquakes.
• New seismic standard (新耐震基準): Buildings approved from June 1981 onward. These meet modern earthquake resistance requirements.
• New new seismic standard (新・新耐震基準): For wooden houses, buildings constructed after 2000 meet even stricter standards.

Rule of thumb for foreign buyers: Avoid purchasing any wood-framed house built before 2000. For condominiums, check that the building received construction approval after June 1981. This information is in the property documentation and your agent can confirm it.

Signs of Structural Problems to Look For

During your viewing, watch closely for:

• Cracks in walls or ceilings: Minor surface cracks are common in older buildings, but deep or diagonal cracks can indicate structural settlement.
• Floor levelness: Use your leveling app. A tilt of more than 3/1000 (3mm per 1m) can indicate foundation issues.
• Creaking or soft spots in floors: May indicate water damage, rot, or termite damage — common in Japan's humid climate.
• Water stains or mold marks: Check ceilings, corners near windows, bathrooms, and kitchen areas carefully.
• Rust or staining around plumbing fixtures: Indicates pipe age or water quality issues.

For detailed information on inspection costs and what home inspectors look for, the guide at Wagaya Japan's home inspection journal provides an excellent breakdown.

Room-by-Room Viewing Checklist

Living Areas and Bedrooms

• Check ceiling height (standard in Japan is approximately 2.4m — lower than Western norms)
• Verify natural light by checking window orientation and size
• Look for shadows from neighboring buildings — ask the agent about planned construction nearby
• Check mobile and WiFi signal strength
• Assess closet depth and storage capacity (Japanese storage is often smaller than Western buyers expect)
• Test air conditioning units: check manufacture dates on the unit stickers — units over 10 years may need replacement soon

Kitchen

• Test water pressure at the sink
• Check drainage smell (open the drain briefly)
• Assess ventilation hood functionality
• Count number of burners (gas vs. IH induction)
• Inspect under the sink for water damage or mold

Bathroom and Toilet

• Check bath and shower water pressure
• Inspect for mold, especially around tile grout and ceiling corners
• Verify ventilation fan/drying function works (critical in Japan's humid summers)
• Check tub size — Japanese baths are deep but often short
• Test bidet seat functionality

For Condominiums: Common Area Assessment

The condition of a condo's common areas tells you as much about the building as the unit itself:

• Entrance and lobby: Clean and well-maintained?
• Bulletin board: Are notices current and management information up to date?
• Hallways and stairwells: Clean, no rust, no water stains?
• Elevators: Check the maintenance certificate (usually posted inside) — is it current?
• Trash area: Well-organized and clean? This reflects community management quality.
• Parking lot: Organized and maintained?
• Security: Are there working auto-locks, security cameras, and intercoms?

A poorly managed building can mean high future repair costs and poor quality of life. For a complete checklist of naiken inspection points in Japan, Gaijin Buy House's property viewing guide is an excellent reference.

Evaluating the Neighborhood: What to Check Beyond the Unit

The property itself is only part of the equation. Japan's neighborhoods vary enormously, and what seems like a quiet street during a weekday afternoon viewing may be completely different during rush hour or on weekends.

Transportation Access

• Walk the actual route to the nearest train or bus station — do not rely on map estimates
• Time the walk yourself and note any hills, road crossings, or poor lighting
• Check rush-hour congestion on the train line (overcrowded lines are a significant daily quality-of-life factor)

Essential Amenities

• Locate the nearest supermarket, convenience store, and pharmacy
• Find the nearest bank or ATM with foreign-language support
• Identify nearby hospitals, ideally with English-speaking staff or multilingual services

Safety and Noise

• Visit the area on both a weekday and a weekend
• Check the neighborhood at night — lighting, foot traffic, and noise levels change significantly
• Look for flood hazard maps (ハザードマップ, hazard map) — your local municipal office publishes these online. Many riverside or low-lying areas in Japan have flood or landslide risk.

Language and Communication During Viewings

One of the biggest challenges for foreign buyers is navigating Japanese-language communication during viewings and negotiations. Keep these points in mind:

Choose a bilingual agent: A real estate agent who speaks both Japanese and English (or your language) is your most valuable asset. They can translate key details the listing agent communicates verbally during the viewing — information that will not appear in writing.

The Jyuuyo Jiko Setsumei (重要事項説明): Before any purchase contract is signed, the real estate agent is legally required to provide you with a written "Explanation of Important Matters." This document is in Japanese and covers legal encumbrances, zoning, utility status, and known defects. Request a translated summary from your agent.

Request an interpreter for key moments: For the formal explanation of important matters, ask that any interpreter who assists signs the documentation to confirm accuracy. This protects you legally.

Professional Home Inspections: A Must-Have for Resale Properties

Unlike many Western countries, professional home inspections are not yet standard practice in Japan — many buyers skip them entirely. For foreign buyers, this is a significant risk.

What a home inspection covers:

• Structural integrity and foundation assessment
• Roof and exterior wall condition
• Water damage, leaks, and plumbing systems
• Electrical system status
• Pest damage (termites are common in wooden structures)

Cost of home inspections in Japan:

Japan's 2020 Civil Code revision strengthened buyers' protections, shifting the framework from "hidden defect liability" to "liability for nonconformity with contract" — meaning sellers are more accountable for defects discovered after purchase. However, proactively commissioning your own inspection before signing remains the safest approach.

Choose an inspector who:

• Holds a First-Class Architect License (一級建築士)
• Is completely independent from the seller and real estate agent
• Has substantial construction supervision experience (not just inspection)
• Can provide reports in English, or use a qualified interpreter

Making an Offer After Your Viewing: What Happens Next

Once you've identified a property you want to pursue after your viewing(s):

1. Submit a Letter of Intent (買付証明書, kaitsuke shoumei-sho): This is a non-binding written expression of interest. Include your offered price and any conditions.
2. Price negotiation: Unlike in many Western markets, Japanese property transactions typically occur close to the asking price. Significant negotiation is uncommon, though properties that have been listed for extended periods may be more flexible.
3. Earnest money deposit (手付金, tetsukekin): Upon offer acceptance, you'll typically pay ¥100,000–¥500,000 to confirm your commitment. This is applied to the final purchase price.
4. Purchase contract signing: Conducted in Japanese. Your agent should provide a full explanation in your language.
5. Settlement: The full purchase process from initial offer to settlement typically takes 60–90 days.

For a full breakdown of costs beyond the purchase price, see our article on Hidden Costs and Fees When Buying Property in Japan. Plan for an additional 5–10% of the purchase price in transaction costs, taxes, and fees.

Japan's Current Property Market Context for Buyers

Understanding market conditions can help you set realistic expectations during viewings and negotiations.

Japan has a record 13.8% nationwide vacancy rate, driven by significant population decline (approximately 550,000 people in 2024 alone). This means there is no shortage of properties available — buyers have more choice and less pressure than in many other major markets.

However, desirable urban properties in Tokyo, Osaka, and Kyoto remain competitive. In July 2025, the average price of an existing condominium in the Tokyo metropolitan area was approximately ¥50 million, compared to ¥90 million for a new unit.

Key Takeaways for Foreign Buyers

Property viewings in Japan reward preparation. Buyers who come equipped with a checklist, the right tools, and a bilingual agent consistently make better decisions than those who rely solely on online listings and casual walkthroughs.

Checklist summary before your naiken:

• Bring smartphone, measuring tape, flashlight, notebook, leveling app
• Check earthquake compliance year (post-1981 for condos, post-2000 for wooden houses)
• Visit at multiple times of day and in different weather
• Assess both the unit AND common areas
• Commission a professional home inspection before signing
• Confirm all documentation with a bilingual agent
