Understanding Japanese
Property Listings

Japanese listings are dense with abbreviations, kanji, and unit systems that don't exist in Western real estate. This guide decodes every field you'll encounter — from 万円 prices to 築年数 building age to the 1981 seismic dividing line.

Understanding Japanese property listings

Reading a Real Listing Card

Before diving into individual terms, here's what a typical Okinawa property listing looks like — and what every field actually means. This is modeled on the format used by e-uchina.net, the main Okinawa real estate portal, and the listings you'll find on this site.

Reading this card: A 3-bedroom condo (3LDK) in Yomitan Village, 75 m² on the 4th floor of an 8-floor RC building built in 1998 — safely post-1981 seismic code. Price is ¥23.8 million (2,380 × 10,000). Add ¥20,500/month in mandatory fees on top of any mortgage payment.

The 万円 Price System

Japan counts large numbers in units of 10,000 (万, man). Property prices are always listed in 万円 — you multiply the number you see by 10,000 to get yen, then divide by your exchange rate for dollars.

As listedIn yenApprox. USD (¥150/$)What you're looking at
500万円¥5,000,000~$33,000Cheap rural land or a rundown akiya
1,500万円¥15,000,000~$100,000Older apartment or small house inland
2,500万円¥25,000,000~$167,000Solid 3LDK mansion in mid-Okinawa
4,000万円¥40,000,000~$267,000Newer condo in Chatan or coastal Naha
8,000万円¥80,000,000~$533,000High-end oceanfront or new-build luxury

Quick mental math: Drop four zeros and convert. 3,200万 → ¥32,000,000 → divide by 150 → roughly $213,000. At ¥145/$, same property is ~$221,000. The FX rate matters — a 10-yen swing on a ¥30M property is $20,000.

Layout Codes: K, DK, LDK

Every Japanese listing shows a layout code that tells you how many rooms the property has and what kind of shared space connects them. The number prefix is the bedroom count; the letters describe the main living area.

1R
20–28 m²
Single room — kitchen shares sleeping space. No door between them.
1K
22–32 m²
One bedroom separated from kitchen by a door or divider.
1DK
30–42 m²
One bedroom plus a combined dining-kitchen area (no living room).
1LDK
40–58 m²
One bedroom plus a full living-dining-kitchen space. Good for a couple.
2LDK
55–75 m²
Two bedrooms plus LDK. Most popular family size in Okinawa.
3LDK
70–95 m²
Three bedrooms plus LDK. Standard for families; common in Okinawa houses.
4LDK
90–130 m²
Four bedrooms. Usually a standalone house (一戸建て) in Okinawa.
+S
varies
Plus a "service room" (納戸/サービスルーム) — a smaller room with no window, not legally a bedroom.

The "S" (service room) catch: A 2SLDK listing is not a 3-bedroom. The S room has no legally required window — it's often used as storage, a study, or a nursery, but don't count on sunlight. In Okinawa's humid climate, windowless rooms grow mold fast without a dehumidifier.

Property Types: Mansion, Apato, Ikkodate

Three words appear on every Okinawa listing. They mean something very specific in Japanese real estate — not what they suggest in English.

mansion
Concrete apartment building
3+ floors, RC or SRC construction. Has an entrance lobby, often auto-lock. Better soundproofing and insulation than apato. The dominant listing type in coastal Okinawa cities.
apato
Wooden apartment building
Usually 2 stories, wood or light-steel frame. Lower rent, thinner walls, noisier. Common in rural towns and Okinawa City. Expect more humidity and insect issues than a mansion.
ikkodate
Detached house
A standalone single-family home. Comes with land (土地). Most Okinawa houses are 3–4LDK, often two-story concrete. You own the building and the plot — very different from buying a mansion unit.
chuko / shinchiku
Used / New construction
中古 (chuko) = pre-owned. 新築 (shinchiku) = brand new, never lived in. New construction in Japan loses 10–20% of its value the moment someone moves in — the "new car" effect. Most listings on e-uchina.net are 中古.

Building Structure Codes

The 構造 (kōzō) field tells you what the building is made of. This matters enormously for earthquake safety, soundproofing, humidity resistance — and in Okinawa specifically, typhoon resilience.

Code Japanese Full name What it means Okinawa rating
RC Reinforced Concrete Steel rebar embedded in concrete. The standard for Okinawa mansions. Strong against typhoons and earthquakes; good sound insulation; retains heat in summer. Excellent
SRC Steel-Reinforced Concrete Steel frame + rebar + concrete. Used in larger, taller buildings. Superior structural strength. Rare in Okinawa residential but exists in newer high-rise condos. Superior
S Steel Frame Steel frame without concrete cladding. Common in light-steel apato. Moderate typhoon resistance, thinner walls, noisier. Moderate
木造 Wood Frame Traditional wooden construction. Cheapest, noisiest, worst against typhoons. Very rare in Okinawa (where concrete has been dominant since WWII). Almost always apato. Avoid
軽量鉄骨 Light Steel Frame Thin steel sheet construction. Cheaper than RC, better than wood. The typical material for 2-story apato. Acoustics and insulation are noticeably worse than RC. Fair

Okinawa is overwhelmingly concrete: The US military rebuilt Okinawa in concrete after WWII, and typhoon culture reinforced that preference. You'll rarely see 木造 (wood) listings on Okinawa main island. If you do, look carefully at the typhoon shutter situation.

Measurements: m², Tsubo, and Jo

Japanese listings use three area units — sometimes on the same listing. All three can appear in a single property card, describing different things.

1 坪
1 tsubo
= 3.306 m²
= 35.58 sq ft
= 2 tatami mats
1 畳
1 jo (tatami)
= 1.653 m²
= 17.79 sq ft
= ½ tsubo
1 m²
1 square meter
= 0.3025 tsubo
= 0.605 tatami
= 10.76 sq ft

Where each unit appears:

  • m² (平方メートル) — used for apartment floor area (専有面積) and building area (建物面積). This is the metric you'll see most often on modern listings.
  • 坪 (tsubo) — used to price land and occasionally buildings. Land listings often show price-per-tsubo (坪単価). Okinawa prices typically run ¥30,000–¥200,000 per tsubo depending on location and zoning.
  • 畳 (jo) — used to describe individual room sizes within a listing. A "6畳 bedroom" is about 9.9 m² or 107 sq ft — small by Western standards but normal in Japan.

専有面積 vs 建物面積: Apartments list 専有面積 (private floor area — what you actually own). Houses list 建物面積 (total building area). For houses, also check 土地面積 (land area) — you need both to understand what you're getting. The land area often matters more for pricing than the building itself.

Building Age and the 1981 Seismic Line

The 築年数 (chikunensū) field shows when the building was constructed. In Japan, the construction year is arguably the most important number in a listing after the price — because it determines which earthquake safety standard the building was built to.

Before June 1981 — 旧耐震 (kyu-taishin)
Old seismic standard
Required to withstand a magnitude 5 earthquake without collapse. After the 1995 Kobe earthquake, ~28% of wooden homes built to this standard collapsed. Many Japanese banks will not offer mortgages for pre-1981 properties. Treat these with caution unless a certified seismic inspection has been done.
June 1981 onwards — 新耐震 (shin-taishin)
New seismic standard
Must withstand magnitude 6+ without collapse. Collapse rate in 1995 Kobe: ~9% (vs 28% for old standard). This is the minimum you should target for a purchase. Properties built after June 1981 qualify for most Japanese mortgages and standard earthquake insurance.
2000 revision onwards
Enhanced standard (wood-frame homes)
Required continuous concrete foundations and metal connectors at key joints. Introduced Seismic Grades 1–3. Grade 3 (最高等級) withstands 1.5× the legal minimum — the gold standard for wooden houses. For concrete RC/SRC buildings in Okinawa, the 1981 standard is already robust; the 2000 revision mainly affects wood-frame homes.

Quick rule of thumb for Okinawa: If the listing shows 築 1981年以前, ask for a seismic inspection report before getting serious. If it shows 築 1981年以降, you're in new-standard territory. For RC mansions built post-1990, seismic concerns are usually secondary to typhoon shutters and humidity.

Key Listing Fields Decoded

chikunengetsu
Year & month built
The date the building received its completion certificate. Compare to June 1981 for seismic standard. Older buildings can still be excellent — check condition, not just age.
sen'yū menseki
Private floor area
The square meters you own inside the building. Does not include common areas (hallways, parking lot, lobby). The number used for price-per-m² comparisons.
tochi menseki
Land area
Total plot size in m² or tsubo. Shown on house (ikkodate) listings. For mansions (condos), this field is typically blank or shows the building's total footprint.
kanrihi
Monthly management fee
Paid monthly by all unit owners in a mansion building. Covers building maintenance, cleaning, elevator upkeep. Ranges ¥5,000–¥25,000/month for typical Okinawa condos.
shūzen tsumitatekin
Repair reserve fund contribution
Monthly contribution to the building's major repair fund (roof, exterior, elevator replacement). Not optional. Add this to management fee for your real monthly overhead — often ¥5,000–¥20,000/month.
shozai-kai / tate
Floor / Total floors
Format: "4F / 8F" means unit is on the 4th floor of an 8-floor building. Higher floors = better views and breeze in Okinawa; ground floor = easier typhoon boarding access.
shoyūken / shakuchiken
Freehold / Leasehold land
所有権 = you own the land outright (preferred). 借地権 = you own the building but lease the land from someone else — expect monthly ground rent and renewal complexity. Avoid unless the price reflects the leasehold discount.
yōto chiiki
Zoning / Land use designation
Japan has 13 zoning categories. Key ones: 第一種低層住居専用 (low-rise residential, quiet), 商業地域 (commercial — noisy, good for investors), 準工業地域 (semi-industrial — watch for nearby factories).

Negotiation Status — What Those Labels Mean

Okinawa listings often carry a status badge that tells you where the property is in its sales lifecycle. These are critical — a property marked 売約済 is gone, and you're wasting time requesting details.

keisaichū
Active listing
On the market, no offers yet. Contact the agent — this one is genuinely available.
shōdanchū
Under negotiation
Another buyer is in active talks. Not yet sold — deals fall through. You can register interest, but don't get attached.
mōshikomizumi
Application submitted
A buyer has submitted a purchase application. Very likely to close. Essentially off the market.
baiyakuzumi / keiyakuzumi
Sold / Contracted
Contract signed. This listing is finished. On e-uchina.net these still appear briefly before being removed — move on.

Hidden Costs in the Listing Price

The listed price (物件価格) is not your total cost. Japanese real estate transactions add several mandatory costs on top of the sale price. Budget approximately 7–10% of the purchase price in transaction costs.

CostJapaneseTypical amountNotes
Agent commission 3% + ¥60,000 + tax Legally capped. On a ¥25M purchase: ~¥870,000.
Registration tax 0.4–2% of assessed value Assessed value (固定資産税評価額) is usually 60–70% of market price.
Stamp duty ¥10,000–¥60,000 Based on contract value. Reduced rates apply through March 2027.
Acquisition tax 3–4% of assessed value One-time tax; bill arrives 3–6 months after purchase. Reduction available for primary residences.
Judicial scrivener fee ¥80,000–¥200,000 Handles ownership registration. Required for all transfers.
Annual property tax 1.4% of assessed value/yr Ongoing — billed quarterly. For a ¥25M property, expect ¥100,000–¥200,000/year.

Okinawa-Specific Listing Notes

A few things you'll only see — or see constantly — in Okinawa listings:

  • 台風シャッター (taifū shattā) / 雨戸 (amado): Typhoon storm shutters on all windows. Listings that mention these prominently are flagging a key feature — in Okinawa, proper shutters are not optional. Check that every window has coverage before buying.
  • 駐車場 (chūshajō): Parking. Many Okinawa listings include dedicated parking (1台 = 1 space, 2台 = 2 spaces). Island life is car-dependent — confirm parking before falling in love with a property.
  • 沖縄県 / 島内 (Okinawa-ken / tō-nai): Listings will specify the city or village. Remember that "Okinawa City" (沖縄市) and "Okinawa Prefecture" (沖縄県) are different things — Okinawa City (Koza) is a specific municipality in central Okinawa.
  • RC dominance: Unlike mainland Japan where wood-frame homes are common, virtually all Okinawa residential buildings are RC. This is a feature, not a quirk — it means typhoon and earthquake resistance even in older stock.
  • 米軍基地 (bei-gun kichi): US military base proximity. Some listings will flag this (positively or negatively). Properties near bases in Chatan, Ginowan, Yomitan, and Okinawa City see specific demand from military families, which both supports prices and limits some neighbors' preferences.
  • 海が見える (umi ga mieru): "Ocean view" — one of the most common value-add phrases in Okinawa listings. Confirm which direction and what floor; an ocean view on the 2nd floor of an Onna Village property can vanish when the neighbor builds a wall.

Most Okinawa listings originate from a handful of portals. The same property often appears across multiple sites — prices should match; if they don't, the newer listing is more likely to be current.

Frequently Asked Questions

Why is the listed price sometimes different from what I see on another site?
Agencies are allowed to list the same property at different prices — the seller sets a minimum and agents sometimes add their own buffer. The same property may show at 2,380万 on one site and 2,400万 on another. Always ask the listing agent for the seller's asking price and whether there's room to negotiate.
What does 価格応相談 mean?
価格応相談 (kakaku ō sōdan) means "price negotiable — contact us." The seller hasn't committed to a fixed price. This often appears on land listings or unique properties. It's an invitation to negotiate, not a red flag.
Is a 築40年 (40-year-old) building too old to buy?
Not necessarily in Okinawa. A 1985 RC mansion in Okinawa is well within the new seismic standard and likely solid concrete — far more durable than a 40-year-old wooden house anywhere else in Japan. The questions to ask: Has the building been renovated? Is the repair reserve fund healthy? Has there been any water ingress or rebar corrosion (塩害, salt damage from ocean air)? In coastal Okinawa, salt air accelerates concrete deterioration, so exterior condition matters more than in inland locations.
What is 塩害 and why does it matter in Okinawa?
塩害 (engai) means salt damage — corrosion caused by salt-laden ocean air. It's a real concern within a few hundred meters of the coast. Salt air accelerates rusting of rebar inside concrete, eventually causing cracking and spalling. Inspect older coastal properties carefully: look for surface cracks, rust stains, and bulging concrete. Ask about the building's salt-damage inspection history.
Can I negotiate the price on a Japanese listing?
Yes — Japanese real estate prices are negotiable, though the culture is less aggressive than in some Western markets. A 3–8% reduction from the listed price is common for properties that have been sitting for 3+ months. The listing agent represents the seller, so consider having your own buyer's agent or at least a clear anchor offer ready. Properties marked 商談中 (under negotiation) are harder to negotiate on — the seller has leverage.
What does "DOM" mean on this site's listings?
Days on Market — how long the property has been tracked in our database. A low DOM (under 30 days) means it's fresh. High DOM (over 180 days) suggests the price may be too high, there's a problem with the property, or it's in a less desirable area. Use DOM alongside price history (look for 価格変更, price reductions) to gauge seller motivation.
