STRATEGY & YIELD
The Gross Yield Trap: How Japanese Listing Yields Are Calculated to Flatter Sellers
Japanese listing sites quote gross yield (hyomen rimawari) — a figure that excludes vacancy, taxes, and fees.
On this page 7
TL;DR: Hyomen rimawari is the standard gross yield figure on every Japanese investment property listing. It uses 100% occupancy, current rent, and zero costs. Sellers and agents prefer it because it produces the highest possible yield number. Foreign buyers who don’t know what they’re looking at will consistently overpay. This issue explains the construction, the incentive behind it, and how to translate it into something useful.
I pulled a listing from a major Tokyo portal last week. Headline: 9.1% yield, a 1R in Katsushika-ku, asking ¥7.8M. The unit had been on the market for four months.
Nine-point-one sounds like a lot. It’s designed to. Here’s how they got there — and what the honest number looks like.
[OPERATOR NOTE — add your own first-hand detail here: a real deal, number, or scar.]
How Gross Yield (Hyomen Rimawari) Is Constructed
Hyomen means “surface” or “face.” Rimawari means “yield” or “return rate.” Face yield. The language wasn’t subtle.
The formula:
Gross yield (hyomen rimawari) = (Monthly rent × 12) ÷ Asking price × 100
For the Katsushika unit:
- Monthly rent (current tenant): ¥59,000
- Asking price: ¥7,800,000
- Gross yield: (¥59,000 × 12) ÷ ¥7,800,000 × 100 = 9.08%
Three things that formula does not contain: vacancy, costs, or taxes. The number assumes the tenant pays every month, forever, and you have no expenses. No property management, no HOA fees, no repair reserves, no insurance, no tax. Pure income divided by price.
Legal. Standard. Calibrated to produce the largest number a seller can honestly put in front of a buyer.
What Sellers and Agents Know (That Buyers Don’t)
The Japanese investment property market has a well-understood information asymmetry. Sellers and experienced agents know that:
The current rent is often below market. Tenant protection under Japan’s land and building lease law makes rent increases difficult without tenant cooperation. Long-term tenants in older buildings frequently pay 10–20% below current market rates. The listing yield is calculated on the rent the tenant is actually paying — which could be a five-year-old rent for a unit that would command ¥7,000 more per month today if vacant.
Occupancy looks permanent until it isn’t. An occupied building justifies the full-rent assumption in the yield calculation. The moment that tenant leaves, the owner faces: vacancy period (often 1–3 months), restoration costs, key exchange fees, and a new lease-up via an agent at 1 month’s rent commission.
The asking price is negotiable, but the yield headline is set to anchor high. If a seller wants ¥7.8M, they set the listing yield based on ¥7.8M. The deal might close at ¥7.2M — which would push true net yield higher — but the headline draws the interest first.
Why 9.1% in Katsushika Is Not What It Looks Like
Figures below are illustrative — representative of this property type and market segment, not a specific audited transaction.
Back to that 1R. Here’s the translation from headline to reality:
Gross potential income (100% occupancy): ¥708,000
| Deduction | Amount |
|---|---|
| Vacancy (12% — older building, less central ward) | −¥84,960 |
| Property management fee (6% of collected rent) | −¥37,381 |
| HOA fees — owner pays when vacant too | −¥15,600 (¥1,300/month) |
| Building repair reserve | −¥13,200 (¥1,100/month) |
| Fixed-asset tax + city planning tax | −¥38,000 (estimated) |
| Fire & earthquake insurance | −¥14,000 |
| Minor repairs/contingency | −¥15,000 |
Total deductions: ¥218,141
Net operating income: ¥708,000 − ¥218,141 = ¥489,859
Net yield on asking price: ¥489,859 ÷ ¥7,800,000 = 6.28%
Already 2.8 percentage points below the headline. But the unit had been sitting for four months — which means either the asking price is too high or there’s something wrong with the building. I’d want to negotiate to ¥7.0M minimum. At ¥7.0M, net yield is 6.99%. Acceptable for that location if the building is sound.
Headline and investable number: 2–3 percentage points apart before you’ve touched financing.
The Three Numbers Every Listing Headline Hides
When you see a gross yield headline, flag three things the seller chose not to show you:
1. The age and condition of the building. Yield is partly a function of price. Old buildings are cheaper. Cheap price ÷ same rent = higher headline yield. But old buildings carry higher repair reserves, more frequent vacancy, and accelerating depreciation risk. The 9% yield building is often old. That matters.
2. The actual monthly costs charged to the owner. HOA fees and repair reserves vary enormously. A ¥3,000/month reserve versus a ¥18,000/month reserve is the difference between a viable investment and a cash drain. Neither number appears in gross yield.
3. Whether the current rent is achievable on re-lease. If the tenant leaves and the building has aged, can you re-lease at ¥59,000? In some Katsushika sub-areas, comparable units now lease for ¥54,000–¥56,000. That’s 5–8% below the income the gross yield is built on. Never assume current rent = relettable rent without checking the portals yourself.
How to Build Your Own Yield Number Before Making an Offer
You don’t need the seller to give you a better number. Build it yourself.
Step 1: Get the HOA fee and repair reserve amounts. Ask the agent. If they can’t provide them, request the building bylaws (kanri kiyaku) or the most recent general meeting minutes. Both have the numbers.
Step 2: Check current market rents for comparable units. Twenty minutes on SUUMO or Homes.co.jp, filtering by building age, station distance, and unit size. What are vacant units actually listing for? That is your realistic relettable rent.
Step 3: Apply a vacancy rate. For Tokyo’s 23 wards, 8–12% is reasonable depending on area and building age. For regional properties, 15–20%.
Step 4: Estimate property tax. Ask the seller for the most recent fixed-asset tax notice. They have it. If they’re reluctant, that itself is information.
Step 5: Build your net yield. Gross potential income (using your market rent check, not current rent) minus all costs equals NOI. NOI divided by your expected purchase price equals net yield.
If that number is acceptable, make an offer. If not, negotiate on price until it is — or walk.
Where This Goes Wrong
- Accepting gross yield as a shorthand for quality. High headline yield often indicates a lower-quality building or less desirable location. The yield is higher because the price is lower. Sometimes that trade-off is worth it. Often it isn’t.
- Not checking whether the building is already running a special repair assessment. Major renovation cycles (typically every 12–15 years) sometimes require one-time special levies when the reserve fund is underfunded. Buying just before a ¥500,000 special assessment wipes out a year of net income.
- Trusting “current tenant pays reliably” as a long-term assumption. Japan has extremely strong tenant protections. A tenant who stops paying is very difficult and expensive to remove. The listing yield tells you nothing about tenant quality.
- Ignoring the trend in repair reserves. Regulations introduced in 2022 push building management associations toward actuarially funded reserve schedules. Older buildings with historically low reserves are now required to catch up. The ¥1,100/month reserve today may be ¥3,500/month in three years.
FAQ
Q: Is jisshitsu rimawari the same as net yield? A: Closer to it, but what gets included varies. Some agents define jisshitsu rimawari as gross minus management fees and HOA/reserves, but still exclude property tax and vacancy. Always ask: “What costs are included in your net yield calculation?”
Q: What’s a typical gap between gross yield and true net yield? A: In Tokyo’s 23 wards, figure 2.5–3.5 percentage points for a property 20+ years old. For newer (post-2000) buildings with lower reserves, the gap is somewhat smaller — maybe 1.8–2.5 points.
Q: If a listing has been on the market 3+ months, does that mean the price is wrong? A: Often yes. The Japanese investment property market moves — good deals at honest prices get picked up quickly by domestic investors who run the same yield calculations. Extended time on market usually means overpriced or there’s something disclosed in the mandatory property description document that’s scaring buyers off. Ask why it’s still available.
Q: Can I negotiate based on net yield rather than asking price? A: Yes — and this is one of the most effective tactics in Japanese property negotiation. State the net yield you need (say 5.5%), show your cost calculation, and work backwards to a price. Some sellers respond better to “I can justify ¥6.8M based on realistic income and costs” than to “I want a discount.”
Q: Do all Japanese investors use gross yield to evaluate deals? A: Experienced domestic investors do not. They use their own calculations and sometimes don’t even look at the headline yield. But inexperienced buyers — including many foreigners — take gross yield at face value. Sellers know this.
