Japan is the higher earner — average annual wage of $49,446 against $38,489 in Czech Republic, about 28% more in purchasing-power terms.
Country-level figures — Brno is not Czech Republic and Osaka is not Japan, and both cities typically pay above their national average. Gross, before tax: see take-home pay by country for what lands in the account.
Distance
How far is Brno from Osaka?
Brno is about 8,910 km (5,540 mi) from Osaka in a straight line — roughly 11 h 15 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 Brno warmer than Osaka?
Osaka is the warmer city: January highs average 9°C vs 1°C, and July 32°C vs 25°C. Osaka gets noticeably more sun — about 370 more sunshine hours per year.
| Month | Brno | Osaka |
|---|---|---|
| January (high / low) | 1° / -4°C | 9° / 2°C |
| July (high / low) | 25° / 14°C | 32° / 24°C |
Continental like Prague but slightly warmer and drier — cold winters, warm summers, low rainfall by Central European standards.
Humid subtropical, similar to Tokyo. Hot wet summers, mild dry winters; rainy season (tsuyu) Jun-Jul; typhoon risk Sep-Oct.
Osaka edges Brno by the narrowest margin at 0.1 points, suggesting these Central European and Japanese cities offer nearly identical appeal despite vastly different geographies and cultures.
Both cities score in the mid-5s range, placing them in comparable tiers globally rather than in distinct performance categories.
If choosing between them, prioritize which specific amenities matter most—Osaka's strengths likely differ fundamentally from Brno's despite their similar overall scores.

Score-by-score, side-by-side
Each axis is scored independently with disclosed weights and a calculation string.
The exact scores and winners:
| Axis | Brno | Osaka | Winner |
|---|---|---|---|
| Affordability | 7.4 | 7.8 | Osaka +0.4 |
| Quality of life | 7.2 | 7.4 | Osaka +0.2 |
| Remote-work friendliness | 6.0 | 8.4 | Osaka +2.4 |
| Healthcare | 5.0 | 5.5 | Osaka +0.5 |
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%)29
- Rent index (weight 40%)21
How this is calculated
Affordability = ((100 − costIndex)/100 × 0.6 + (100 − rentIndex)/100 × 0.4) × 10. For Brno: ((100 − 29)/100 × 0.6 + (100 − 21)/100 × 0.4) × 10 = 7.4.
Brno sits well below the New York baseline on both cost-of-living and rent. Budgets stretch further here than in benchmark Tier-1 cities.
Quality of life
- Safety index (weight 40%)75
- Healthcare index (weight 35%)72
- Air quality index (weight 25%)68
How this is calculated
QoL = (safety/100 × 0.4 + healthcare/100 × 0.35 + airQuality/100 × 0.25) × 10. For Brno: (75/100 × 0.4 + 72/100 × 0.35 + 68/100 × 0.25) × 10 = 7.2.
Brno scores good 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%)100 Mbps
- Effective income tax (lower = better) (weight 30%)9.0%
- Cost-of-living (lower = better) (weight 25%)29
How this is calculated
RemoteWork = (min(Mbps/300, 1) × 0.45 + (1 − incomeTax) × 0.3 + (100 − costIndex)/100 × 0.25) × 10. For Brno: (min(100/300, 1) × 0.45 + (1 − 0.0901) × 0.3 + (100 − 29)/100 × 0.25) × 10 = 6.
Brno works for remote work but isn't optimized for it: internet 100 Mbps, income tax 9%, cost index 29.
Healthcare
- Healthcare quality index (weight 70%)72
- Healthcare out-of-pocket / month (lower = better) (weight 30%)559
How this is calculated
Healthcare = (qualityIndex/100 × 0.7 + max(0, 1 − OOP/500) × 0.3) × 10. For Brno: (72/100 × 0.7 + max(0, 1 − 559/500) × 0.3) × 10 = 5.
Brno has trade-offs in healthcare: quality is good, typical out-of-pocket cost is ~559 CZK/month. Cross-border insurance closes the gap.

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%)7.9%
- Cost-of-living (lower = better) (weight 25%)25
How this is calculated

Osaka combines fast internet (250 Mbps median), a 8% effective income tax and cost index 25 — 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%)4624
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 − 4624/500) × 0.3) × 10 = 5.5.
Osaka has trade-offs in healthcare: quality is good, typical out-of-pocket cost is ~4624 JPY/month. Cross-border insurance closes the gap.
Monthly cost delta: Brno vs Osaka
Normalized to CZK at 1 JPY = 0.1382 CZK.
| Category | Brno | Osaka | Change |
|---|---|---|---|
| housing | CZK 21,206 | ¥112,000 | -27% |
| food | CZK 5,431 | ¥55,491 | +41% |

| leisure | CZK 5,990 | ¥33,030 | -24% |
| healthcare | CZK 559 | ¥4,624 | +14% |
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 food: Osaka spends 10.5 percentage points more of its budget on it (24% vs. 14%). If you're sensitive to that category, weight the per-axis scores accordingly.

Salary equivalence: Brno ↔ Osaka
What earning the same purchasing power costs in each city. Cost-adjusted using the local cost-of-living index (Brno = 29, Osaka = 25); currency-converted at 1 JPY = 0.1382 CZK. Tax differences are not modeled.
| Brno gross | Osaka equivalent |
|---|---|
| CZK 40,000 | ¥249,426 |
| CZK 75,000 | ¥467,673 |
| CZK 120,000 | ¥748,277 |

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: Brno vs Osaka
Brno (Europe/Prague) 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: Brno observes daylight saving while Osaka doesn't, so the gap shifts by an hour part of the year.
Official: Czech · English: Moderate · Local language: Useful
Czech tech hub with a large international-student population — English is moderate in the center and IT firms; Czech expected in admin and services.
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 (Brno) and 2026-05-28 (Osaka).
- FX rate. 1 JPY = 0.1382 CZK, 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
Data as of . Last reviewed .
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 Brno 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.
