Overall: Osaka wins by 1.5 points
Population & size
Is Hanoi bigger than Osaka?
Hanoi is the bigger city: about 8.0M people versus Osaka's 2.7M — roughly 3.0× larger.
City-proper / metro population estimates. Size is one input — scroll on for cost of living, salary equivalence and quality-of-life scoring.
National income
Is Hanoi richer than Osaka?
The two sit on different measures, so we are not ranking them: Vietnam is reported as income per capita (GNI, PPP) ($15,850), Japan as average annual wage ($49,446). A full-time wage and a whole-population income per head are not the same quantity.
Country-level figures — Hanoi is not Vietnam 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 Hanoi from Osaka?
Hanoi is about 3,270 km (2,030 mi) from Osaka in a straight line — roughly 4 h 35 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 Hanoi warmer than Osaka?
Hanoi is the warmer city: January highs average 20°C vs 9°C, and July 33°C vs 32°C. Osaka gets noticeably more sun — about 460 more sunshine hours per year.
| Month | Hanoi | Osaka |
|---|---|---|
| January (high / low) | 20° / 14°C | 9° / 2°C |
| July (high / low) | 33° / 26°C | 32° / 24°C |
Humid subtropical — unlike Ho Chi Minh City it has a real winter: gray, drizzly 15°C Jan-Feb. Summers are hot, humid and very wet.
Humid subtropical, similar to Tokyo. Hot wet summers, mild dry winters; rainy season (tsuyu) Jun-Jul; typhoon risk Sep-Oct.
Osaka edges Hanoi by a narrow margin at 5.9 versus 5.4, suggesting both cities compete in the same livability tier despite vastly different scales and development models.
A 0.5-point difference is statistically modest—comparable cities often vary by tenths of points depending on which metrics dominate the scoring rubric.
If choosing between them, prioritize your specific needs in transit, cost, or career prospects rather than relying on headline scores that obscure where each city actually excels.
Data signals

Score-by-score, side-by-side
Each axis is scored independently with disclosed weights and a calculation string.
The exact scores and winners:
| Axis | Hanoi | Osaka | Winner |
|---|---|---|---|
| Affordability | 8.7 | 7.8 | Hanoi +0.9 |
| Quality of life | 4.7 | 7.4 | Osaka +2.7 |
| Remote-work friendliness | 6.3 | 8.4 | Osaka +2.1 |
| Healthcare | 3.6 | 5.5 | Osaka +1.9 |
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%)15
- Rent index (weight 40%)10
How this is calculated
Affordability = ((100 − costIndex)/100 × 0.6 + (100 − rentIndex)/100 × 0.4) × 10. For Hanoi: ((100 − 15)/100 × 0.6 + (100 − 10)/100 × 0.4) × 10 = 8.7.
Hanoi 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%)54
- Healthcare index (weight 35%)52
- Air quality index (weight 25%)28
How this is calculated
QoL = (safety/100 × 0.4 + healthcare/100 × 0.35 + airQuality/100 × 0.25) × 10. For Hanoi: (54/100 × 0.4 + 52/100 × 0.35 + 28/100 × 0.25) × 10 = 4.7.
Hanoi has a mixed quality profile. Safety: fair; healthcare: fair; air: poor. Weigh the weakest axis against your personal priorities.
Remote-work friendliness
- Internet (median Mbps) (weight 45%)100 Mbps
- Effective income tax (lower = better) (weight 30%)12.0%
- Cost-of-living (lower = better) (weight 25%)15
How this is calculated
RemoteWork = (min(Mbps/300, 1) × 0.45 + (1 − incomeTax) × 0.3 + (100 − costIndex)/100 × 0.25) × 10. For Hanoi: (min(100/300, 1) × 0.45 + (1 − 0.12) × 0.3 + (100 − 15)/100 × 0.25) × 10 = 6.3.
Hanoi works for remote work but isn't optimized for it: internet 100 Mbps, income tax 12%, cost index 15.
Healthcare
- Healthcare quality index (weight 70%)52
- Healthcare out-of-pocket / month (lower = better) (weight 30%)782726
How this is calculated
Healthcare = (qualityIndex/100 × 0.7 + max(0, 1 − OOP/500) × 0.3) × 10. For Hanoi: (52/100 × 0.7 + max(0, 1 − 782726/500) × 0.3) × 10 = 3.6.
Hanoi has trade-offs in healthcare: quality is fair, typical out-of-pocket cost is ~782726 VND/month. Cross-border insurance closes the gap.

Affordability
- Cost-of-living index (weight 60%)25
- Rent index (weight 40%)17
How this is calculated
Affordability = ((100 − costIndex)/100 × 0.6 + (100 − rentIndex)/100 × 0.4) × 10. For Osaka: ((100 − 25)/100 × 0.6 + (100 − 17)/100 × 0.4) × 10 = 7.8.
Osaka 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%)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%)7.9%
- Cost-of-living (lower = better) (weight 25%)25
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 − 0.0791) × 0.3 + (100 − 25)/100 × 0.25) × 10 = 8.4.
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: Hanoi vs Osaka
Normalized to VND at 1 JPY = 152.5424 VND.

| healthcare | ₫782,726 | ¥4,624 | -10% |
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 4.9 percentage points more of its budget on it (24% vs. 19%). If you're sensitive to that category, weight the per-axis scores accordingly.

Salary equivalence: Hanoi ↔ Osaka
What earning the same purchasing power costs in each city. Cost-adjusted using the local cost-of-living index (Hanoi = 15, Osaka = 25); currency-converted at 1 JPY = 152.5424 VND. Tax differences are not modeled.
| Hanoi gross | Osaka equivalent |
|---|---|
| ₫40,000 | ¥437 |
| ₫75,000 | ¥819 |
| ₫120,000 | ¥1,311 |
| Osaka gross | Hanoi equivalent |

| ¥75,000 | ₫6,864,407 |
| ¥120,000 | ₫10,983,051 |
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: Hanoi vs Osaka
Hanoi (Asia/Ho_Chi_Minh) and Osaka (Asia/Tokyo) sit 2 hours apart in standard time. A 9-to-5 in one overlaps the other's for 6 hours a day.
Official: Vietnamese · English: Limited · Local language: Recommended
More Vietnamese-required than Ho Chi Minh City — the expat bubble is smaller. English works in Tay Ho and tourist quarters; tonal Vietnamese is hard but even basics go far.
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 (Hanoi) and 2026-05-28 (Osaka).
- FX rate. 1 JPY = 152.5424 VND, 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 Hanoi 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.
