Distance
How far is Johannesburg from Osaka?
Johannesburg is about 13,140 km (8,170 mi) from Osaka in a straight line — roughly 16 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 Johannesburg warmer than Osaka?
Johannesburg and Osaka have broadly similar temperatures across the year. Johannesburg gets noticeably more sun — about 1,070 more sunshine hours per year.
| Month | Johannesburg | Osaka |
|---|---|---|
| January (high / low) | 26° / 15°C | 9° / 2°C |
| July (high / low) | 17° / 4°C | 32° / 24°C |
Subtropical highland (1,750m) — sunny virtually all year. Summer afternoon thunderstorms; dry winters with warm days and near-freezing nights.
Humid subtropical, similar to Tokyo. Hot wet summers, mild dry winters; rainy season (tsuyu) Jun-Jul; typhoon risk Sep-Oct.
Osaka edges out Johannesburg on the Mundevo composite, 5.9 to 5.1 out of 10 — a decisive 0.8-point margin across safety, healthcare, air quality and cost.
A 0.8-point composite gap is large enough that the result holds across most reasonable axis re-weightings. Still worth scanning the per-axis breakdown if you have a non-default priority (e.g. air quality matters more to you than the default 25% weight).
Run the salary calculator for both cities at your target lifestyle before deciding — Osaka winning on quality doesn't mean the gross-salary requirement also lands in your favor. If you're on a balanced tier, the cost-of-living pages for each city carry the full monthly basket and the gross-salary figure.
Data signals
What separates Johannesburg and Osaka
How decisive
Osaka comes out ahead by 0.8 composite points — a clear edge.
Biggest difference
The widest gap is affordability, where Johannesburg leads by 3.2 points.
Where they match
They're most evenly matched on healthcare — within 1.2 points of each other.
Where budgets split most
Healthcare is the line item that diverges most: roughly 48% cheaper in Osaka than Johannesburg.
Size difference
Johannesburg is the larger metro — about 1.6× the population of the other, which shapes commute times, housing supply and how "big-city" daily life feels.
Home internet
Osaka has the faster typical broadband (250 vs 60 Mbps median) — worth weighing if you work remotely or move large files.
Safety
Osaka scores higher on safety (80 vs 18 / 100) — a common deciding factor for families.
Score-by-score, side-by-side
Each axis is scored independently with disclosed weights and a calculation string.
The exact scores and winners:
| Axis | Johannesburg | Osaka | Winner |
|---|---|---|---|
| Affordability | 7.0 | 3.8 | Johannesburg +3.2 |
| Quality of life | 4.2 | 7.4 | Osaka +3.2 |
| Remote-work friendliness | 4.9 | 7.1 | Osaka +2.2 |
| Healthcare | 4.3 | 5.5 | Osaka +1.2 |
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%)39
- Rent index (weight 40%)16
How this is calculated
Affordability = ((100 − costIndex)/100 × 0.6 + (100 − rentIndex)/100 × 0.4) × 10. For Johannesburg: ((100 − 39)/100 × 0.6 + (100 − 16)/100 × 0.4) × 10 = 7.
Johannesburg 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%)18
- Healthcare index (weight 35%)62
- Air quality index (weight 25%)52
How this is calculated
QoL = (safety/100 × 0.4 + healthcare/100 × 0.35 + airQuality/100 × 0.25) × 10. For Johannesburg: (18/100 × 0.4 + 62/100 × 0.35 + 52/100 × 0.25) × 10 = 4.2.
Johannesburg has a mixed quality profile. Safety: poor; healthcare: good; air: fair. Weigh the weakest axis against your personal priorities.
Remote-work friendliness
- Internet (median Mbps) (weight 45%)60 Mbps
- Effective income tax (lower = better) (weight 30%)18.0%
- Cost-of-living (lower = better) (weight 25%)39
How this is calculated
RemoteWork = (min(Mbps/300, 1) × 0.45 + (1 − incomeTax) × 0.3 + (100 − costIndex)/100 × 0.25) × 10. For Johannesburg: (min(60/300, 1) × 0.45 + (1 − 0.18) × 0.3 + (100 − 39)/100 × 0.25) × 10 = 4.9.
Johannesburg works for remote work but isn't optimized for it: internet 60 Mbps, income tax 18%, cost index 39.
Healthcare
- Healthcare quality index (weight 70%)62
- Healthcare out-of-pocket / month (lower = better) (weight 30%)800
How this is calculated
Healthcare = (qualityIndex/100 × 0.7 + max(0, 1 − OOP/500) × 0.3) × 10. For Johannesburg: (62/100 × 0.7 + max(0, 1 − 800/500) × 0.3) × 10 = 4.3.
Johannesburg has trade-offs in healthcare: quality is good, typical out-of-pocket cost is ~800 ZAR/month. Cross-border insurance closes the gap.
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%)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: Johannesburg vs Osaka
Normalized to ZAR at 1 JPY = 0.1190 ZAR.
| Category | Johannesburg | Osaka | Change |
|---|---|---|---|
| housing | ZAR 9,000 | ¥100,000 | +32% |
| food | ZAR 5,000 | ¥42,000 | +0% |
| transport | ZAR 1,100 | ¥9,000 | -3% |
| utilities | ZAR 2,500 | ¥13,000 | -38% |
| leisure | ZAR 4,500 | ¥25,000 | -34% |
| healthcare | ZAR 800 | ¥3,500 | -48% |
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 housing: Osaka spends 12.6 percentage points more of its budget on it (52% vs. 39%). If you're sensitive to that category, weight the per-axis scores accordingly.

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.

Remote work logistics
Time zones and language: Johannesburg vs Osaka
Johannesburg (Africa/Johannesburg) and Osaka (Asia/Tokyo) sit 7 hours apart in standard time. A 9-to-5 in one overlaps the other's for 1 hour a day.
Official: English, Zulu, Afrikaans · English: Native-equivalent · Local language: Not needed
English dominates business and media. The city is massively multilingual (Zulu, Sotho, Afrikaans) but English alone works everywhere that matters for an expat.
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 (Johannesburg) and 2026-05-28 (Osaka).
- FX rate. 1 JPY = 0.1190 ZAR, 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 Johannesburg 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.
