Japan's regional "high-yield" whole buildings, taken apart: how an 8–12% gross headline collapses to 0–5%
Composite-board score: 3.8 · Where it is strong: Net cash flow, Tax friendliness · methodology
The classic product of Japanese property marketing to foreign buyers is the whole wooden apartment building in a regional city — Sapporo, Fukuoka and prefectural capitals, 15–35 years old, listed on portals at gross yields (表面利回り) of 8–12%. This site puts the survey basis on the same screen: Global Property Guide's Sapporo gross yield is only 5.03% and Osaka's 4.78% — so 8–12% is not "the regional market's yield" but a sample selected from ageing stock. Then deduct in full: a 5% management fee; regional vacancy of 10–20% (in depopulating catchments, not Tokyo's 3–5%); fixed asset taxes; insurance; wooden-building repairs (5–10% of income, with lumpy roof, exterior and plumbing events as a normal feature); faster turnover letting fees; and the eventual large-repair or demolition reserve. Bought well with nothing breaking, the net is about 3–5%; bought at the median advertised deal, about 0–2%. Finally, residual value: the building is a depreciating wooden box on land in a catchment losing people every year, whose exit buyer may simply not exist — this segment's liquidity endgame is often a foreign-buyer-to-foreign-buyer chain. Rated below the bar as an explainer: the gap between advertised and kept yield is the most valuable lesson in Japanese property marketing, and this page's job is to make the reader ask about vacancy, repairs and exit before any "high-yield" listing again.
In short: four lines first
Whole buildings about ¥20–80M (listing basis)
8–12%（Regional whole-building apartments: portal-advertised gross yields vs survey basis）
Medium burden (management can be outsourced; repairs, vacancy and exit risk remain yours)
This entry is itself the risk statement: an 8–12% advertised gross collapses to 0–5% after full costs and real vacancy, with residual value and exit liquidity killed together — it does not stand as an investment on a cash-flow board, only as teaching material.
The numbers that matter
Why we think it makes money
It is the largest gross-to-net gap sample in Japan: portal bases of 8–12% and a survey basis of 5.03% coexist for the same city, with "selection" as the layer between them — learning to spot selection is worth more than learning any single market.
Wooden buildings carry hard financial constraints: banks discount them over a 22-year statutory life and refinancing windows are short, so the asset itself runs on a countdown in the accounts — in Japan these are explicit rules, suited to a transferable checklist.
It forms the other pole of Japanese physical property against the Tokyo single-unit entry (No. 43): one pole is about 2% net with full liquidity and certainty; the other is nominal high yield with exit uncertainty. Readers of the Japan page should see the spectrum before choosing where to stand on it.
How to actually get in
- This page offers no buying route (below the bar). If a reader insists on this segment, the minimum self-protection is: bid on the survey basis (city gross around 5%), not the listing basis; demand three years of real rent rolls and repair records; and underwrite a holding period that assumes no exit buyer exists. That already exceeds this site's recommendation and is stated as risk warning only.
What it costs, what it earns
Entry amount: Whole buildings about ¥20–80M (listing basis)
How much work for you: Medium burden (management can be outsourced; repairs, vacancy and exit risk remain yours)
- Vacancy (10–20%) and turnover: regional wooden stock turns over faster, at about a month's rent of letting fees each time.
- The convexity of repairs: wooden roofs, exteriors and plumbing fail in steps, and one major repair can consume several years of "high yield".
- Demolition and disposal: the holding's end may be self-funded demolition (wooden demolition costs are a real negative residual value), not a sale.
Basis: this site uses full-cost net returns only — income minus vacancy, management, maintenance, taxes and insurance, then financing interest, with entry costs in the denominator. See the methodology。

Risks: what could go wrong
What we have not verified yet
The following key figures have not yet been verified; the reason is noted for each item.
- The 0–5% net band is this site's derivation from listing bases and broker worked examples: this segment has no institutional transacted net-yield series, which is itself one reason it can only be an explainer entry.
- The composition of the 8–12% listing sample (age and vacancy distribution) is not disclosed by portals and cannot be standardised.
FAQ
- What exactly separates the advertised yield (hyōmen) from the kept yield?
- Japanese convention: the advertised yield is annual rent at full occupancy divided by price — it does not even deduct vacancy. The kept yield deducts vacancy and turnover, management fees, taxes, insurance, repairs and reserve contributions. On new Tokyo stock the two differ by about 1–1.5 points; on regional wooden stock by 4–7 points. The size of the gap depends on the asset's age and location, not on the seller's character.
- What about Fukuoka — its population is still growing?
- Fukuoka is the regional exception (one of few core cities with net inflow), and its whole-building vacancy and exit conditions are materially better than in shrinking regions — this site's teardown addresses the generic "regional high-yield" sample. Judge city by city: read the city's net population inflow series first, then the listings. The same discipline as entry No. 43 applies in Fukuoka, with different numbers.
- Why is this product sold so specifically to foreigners?
- Because the information gap is largest there: local buyers can read repair records and rent rolls, and they know how banks discount wooden stock; foreign buyers, separated by language and distance, can read only the one big number — the advertised yield. The product's target-customer profile is itself a risk disclosure.
