A comparison of 406 cities in Japan by VanSky score — how comfortable it is to travel in each today. We factor in temperature, wind, sun and conditions by the sea. Sort by any metric and pick your next stop. A comparison of 47 regions of Japan by VanSky score — where it's most comfortable to travel right now. We factor in temperature, wind, sun and conditions by the sea.

The country score (0–100) is computed from all of its cities, not a single point. Cities are grouped into regions, and a region's score is the median of its cities so dense clusters don't outweigh sparse ones. Final score = 0.65 × “best areas” (80th percentile of regions) + 0.35 × “typical conditions” (median of regions), so one warm city can't push the whole country to 100. Each city's score blends warmth (feels-like), sun, rain and wind, adjusted for night temperature and, on the coast, the sea. Data: Open-Meteo, refreshed several times a day.

VanSky Index

A weather comfort index for travel: a 0–100 score. Recalculated daily from live weather data — temperature, rainfall, wind and sun.

80–100 Ideal

60–79 Comfortable

40–59 Acceptable

20–39 Challenging

0–19 Extreme

How it's calculated:

Thermal comfort 35% — temperature + humidity
Sunshine 25% — panel charge, mood; in heat the sun is no longer a bonus
Precipitation 25% — rain → muddy ground
Wind 15% — awning, driving, noise
Extremes override all: frost, heat, storm, downpour
Heat counts by feels-like temperature: at 32°+ the score can’t reach “Comfortable”, muggy nights lower it further
A dangerous day drags the week down: a storm or downpour in the forecast keeps the week from being “Comfortable”
Bonus: warm sea, high panel output

Data: Open-Meteo · Updated several times a day

Frequently Asked Questions

How do I choose the best city in Japan for van life?

Sort cities by the VanSky column — the higher the score, the more comfortable today. Also check solar panel output and sea temperature if you plan to stay near the coast.

What does the VanSky score mean for a city?

A score from 0 to 100 reflects a composite weather assessment: thermal comfort, precipitation level, wind strength, and sunshine. 80+ is ideal, 60–79 is comfortable, 40–59 is acceptable, below 40 is challenging.

How often is data updated for Japan?

Weather data for all cities in Japan is updated several times a day from the Open-Meteo service based on real observations.
