Distance
How far is Brussels from Osaka?
Brussels is about 9,370 km (5,820 mi) from Osaka in a straight line — roughly 11 h 45 m of nonstop flight time.
Great-circle distance, not a routed itinerary; flight estimate assumes ~850 km/h cruise plus 45 minutes of taxi, climb and descent.
Climate
Is Brussels warmer than Osaka?
Osaka is the warmer city: January highs average 9°C vs 6°C, and July 32°C vs 23°C. Osaka gets noticeably more sun — about 500 more sunshine hours per year.
| Month | Brussels | Osaka |
|---|---|---|
| January (high / low) | 6° / 1°C | 9° / 2°C |
| July (high / low) | 23° / 13°C | 32° / 24°C |
Oceanic like Amsterdam — mild, damp and frequently gray. Rain is spread across the whole year; summers are comfortable rather than hot.
Humid subtropical, similar to Tokyo. Hot wet summers, mild dry winters; rainy season (tsuyu) Jun-Jul; typhoon risk Sep-Oct.
Osaka edges Brussels by just 0.2 points (5.9 vs 5.7), suggesting these cities compete in the same tier despite vastly different geographies and urban models.
Both cities score below 6.0, placing them in the middle band of comparable urban centers globally rather than top-tier leaders.
Dig into what each city does well within their 5.7–5.9 range before choosing; the small margin means decision factors beyond raw score likely matter more here.

Score-by-score, side-by-side
Each axis is scored independently with disclosed weights and a calculation string.
The exact scores and winners:
| Axis | Brussels | Osaka | Winner |
|---|---|---|---|
| Affordability | 4.0 | 3.8 | Brussels +0.2 |
| Quality of life | 6.1 | 7.4 | Osaka +1.3 |
| Remote-work friendliness | 4.7 | 7.1 | Osaka +2.4 |
| Healthcare | 8.1 | 5.5 | Brussels +2.6 |
Each axis is a weighted aggregate of underlying indicators normalized to a 0–10 scale. Weights are explicit and disclosed per axis. The composite is the unweighted mean of the four axes — axes are not collapsed further because the underlying trade-offs (e.g. low cost vs poor air quality) are user-dependent.
Affordability
- Cost-of-living index (weight 60%)74
- Rent index (weight 40%)40
How this is calculated
Affordability = ((100 − costIndex)/100 × 0.6 + (100 − rentIndex)/100 × 0.4) × 10. For Brussels: ((100 − 74)/100 × 0.6 + (100 − 40)/100 × 0.4) × 10 = 4.
Brussels is among the more expensive cities tracked. Salary expectations should be calibrated to the high cost base before relocating.
Quality of life
- Safety index (weight 40%)48
- Healthcare index (weight 35%)76
- Air quality index (weight 25%)62
How this is calculated
QoL = (safety/100 × 0.4 + healthcare/100 × 0.35 + airQuality/100 × 0.25) × 10. For Brussels: (48/100 × 0.4 + 76/100 × 0.35 + 62/100 × 0.25) × 10 = 6.1.
Brussels has a mixed quality profile. Safety: fair; healthcare: good; air: good. Weigh the weakest axis against your personal priorities.
Remote-work friendliness
- Internet (median Mbps) (weight 45%)120 Mbps
- Effective income tax (lower = better) (weight 30%)25.0%
- Cost-of-living (lower = better) (weight 25%)74
How this is calculated
RemoteWork = (min(Mbps/300, 1) × 0.45 + (1 − incomeTax) × 0.3 + (100 − costIndex)/100 × 0.25) × 10. For Brussels: (min(120/300, 1) × 0.45 + (1 − 0.25) × 0.3 + (100 − 74)/100 × 0.25) × 10 = 4.7.
Brussels works for remote work but isn't optimized for it: internet 120 Mbps, income tax 25%, cost index 74.
Healthcare
- Healthcare quality index (weight 70%)76
- Healthcare out-of-pocket / month (lower = better) (weight 30%)30
How this is calculated
Healthcare = (qualityIndex/100 × 0.7 + max(0, 1 − OOP/500) × 0.3) × 10. For Brussels: (76/100 × 0.7 + max(0, 1 − 30/500) × 0.3) × 10 = 8.1.
Brussels combines good system quality with a manageable out-of-pocket cost (~30 EUR/month). Travel insurance still recommended for non-residents.

Affordability
- Cost-of-living index (weight 60%)70
- Rent index (weight 40%)50
How this is calculated
Affordability = ((100 − costIndex)/100 × 0.6 + (100 − rentIndex)/100 × 0.4) × 10. For Osaka: ((100 − 70)/100 × 0.6 + (100 − 50)/100 × 0.4) × 10 = 3.8.
Osaka is among the more expensive cities tracked. Salary expectations should be calibrated to the high cost base before relocating.
Quality of life
- Safety index (weight 40%)80
- Healthcare index (weight 35%)78
- Air quality index (weight 25%)60
How this is calculated
QoL = (safety/100 × 0.4 + healthcare/100 × 0.35 + airQuality/100 × 0.25) × 10. For Osaka: (80/100 × 0.4 + 78/100 × 0.35 + 60/100 × 0.25) × 10 = 7.4.
Osaka scores excellent on safety, good on healthcare and good on air. The composite quality-of-life signal is strong.
Remote-work friendliness
- Internet (median Mbps) (weight 45%)250 Mbps
- Effective income tax (lower = better) (weight 30%)12.0%
- Cost-of-living (lower = better) (weight 25%)70
How this is calculated
RemoteWork = (min(Mbps/300, 1) × 0.45 + (1 − incomeTax) × 0.3 + (100 − costIndex)/100 × 0.25) × 10. For Osaka: (min(250/300, 1) × 0.45 + (1 − 0.12) × 0.3 + (100 − 70)/100 × 0.25) × 10 = 7.1.
Osaka combines fast internet (250 Mbps median), a 12% effective income tax and cost index 70 — a strong configuration for remote workers earning in a stronger currency.
Healthcare
- Healthcare quality index (weight 70%)78
- Healthcare out-of-pocket / month (lower = better) (weight 30%)3500
How this is calculated
Healthcare = (qualityIndex/100 × 0.7 + max(0, 1 − OOP/500) × 0.3) × 10. For Osaka: (78/100 × 0.7 + max(0, 1 − 3500/500) × 0.3) × 10 = 5.5.
Osaka has trade-offs in healthcare: quality is good, typical out-of-pocket cost is ~3500 JPY/month. Cross-border insurance closes the gap.
Monthly cost delta: Brussels vs Osaka
Normalized to EUR at 1 JPY = 0.0060 EUR.
| Category | Brussels | Osaka | Change |
|---|---|---|---|
| housing | €1,100 | ¥100,000 | -46% |
| food | €390 | ¥42,000 | -36% |

| leisure | €410 | ¥25,000 | -64% |
| healthcare | €30 | ¥3,500 | -31% |
Where each city's money goes
Two cities can have the same monthly total but very different shapes — one might burn 50% on housing while the other splits more evenly. The composition matters as much as the headline.
The biggest shape difference is leisure: Brussels spends 5.7 percentage points more of its budget on it (19% vs. 13%). If you're sensitive to that category, weight the per-axis scores accordingly.

Salary equivalence: Brussels ↔ Osaka
What earning the same purchasing power costs in each city. Cost-adjusted using the local cost-of-living index (Brussels = 74, Osaka = 70); currency-converted at 1 JPY = 0.0060 EUR. Tax differences are not modeled.
| Brussels gross | Osaka equivalent |
|---|---|
| €40,000 | ¥6,356,757 |
| €75,000 | ¥11,918,919 |
| €120,000 | ¥19,070,270 |

Equivalence here means same cost-of-living purchasing power, not same net take-home. Effective tax rates differ between countries; a salary equivalent on cost can still net more or less depending on the destination's tax regime. Use the calculator for tax-adjusted figures at a specific lifestyle tier.

Remote work logistics
Time zones and language: Brussels vs Osaka
Brussels (Europe/Brussels) and Osaka (Asia/Tokyo) sit 8 hours apart in standard time. A 9-to-5 in one overlaps the other's for 0 hours a day — fully asynchronous collaboration. Note: Brussels observes daylight saving while Osaka doesn't, so the gap shifts by an hour part of the year.
Official: French, Dutch · English: High · Local language: Helpful
Officially bilingual French/Dutch, practically French-first — and the EU-institution bubble runs on English. Daily life works in English in the European quarter; French helps everywhere else.
Official: Japanese · English: Limited · Local language: Recommended
Japanese strongly recommended even more than Tokyo — international corporate cohort is smaller. Osaka-ben (regional dialect) colors local speech; standard Japanese is fine.

How this page is calculated
Data sources
- Mundevo per-city dataset. Cost basket, rent index, safety, healthcare, air quality and median internet for both cities. Reference date: 2026-06-10 (Brussels) and 2026-05-28 (Osaka).
- FX rate. 1 JPY = 0.0060 EUR, used to normalize cost baskets.
- CityScoreCalculator. Four axes (Affordability, Quality of life, Remote work, Healthcare) computed with explicit weights and explanations. See per-axis calculation strings rendered on this page.
- ComparisonService. Per-category cost deltas (housing, food, transport, utilities, leisure, healthcare) normalized to the origin currency.
Update cadence

Calculation
For each of the four axes we compute an independent 0–10 score using the formulas printed beside each axis. The composite is the unweighted mean of the four axes. The overall winner is the city with the higher composite, unless the margin is under 0.05 points — in which case Brussels is shown first as a tiebreaker to keep results stable.
Limitations
- Climate is not scored — we don't yet hold a maintained climate dataset, so weather-driven preferences are not modeled.
- Tax differences between cities in the same country are not modeled (Spain and Germany don't have material regional differences for this dataset).
- Indices are population-level. Personal cost varies with neighborhood, employer benefits and family status.
- Quality-of-life axis weights (safety 0.4 / healthcare 0.35 / air 0.25) are editorial defaults — readers with strong preferences should re-weight manually.
