Best weather apps to consult when visiting Japan

My wish for your trip to Japan is sunny skies, low humidity and a lack of rain clouds. Unless you’re visiting for ski season, in which case, I hope you get all the powdery snow! Unfortunately, the weather doesn’t always cooperate with our plans. However, if you’re prepared, a bad weather day doesn’t necessarily mean a ruined day. Stay ahead of the rain clouds by choosing a weather app in Japan that will give you all the information you need to plan your wardrobe and itinerary for the day.

“There's no such thing as bad weather, only unsuitable clothing.”

Alfred Wainwright

I’ve compared four of the top weather apps for travelers in Japan so you can make the best choice for your trip.


If you’re looking for a basic forecast for your time in Japan, WeatherJapan, created by the Japan Weather Association is a great app. It’s designed for tourists and provides location-based weather and a searchable map. 

WeatherJapan offers an hourly forecast over a 48-hour period with sunrise and sunset times and a 5-day forecast for temperature and weather conditions.

This no-frills app is perfect for the traveler who wants the big picture.

If down-to-the-minute detail makes your heart go pitter patter, AccuWeather MinuteCast® promises “minute-by-minute precipitation forecasts for the next two hours hyper-localized to your exact street address or GPS location.” This technology allows AccuWeather to report on precipitation type and intensity, with detailed start and end times for precipitation.

Their Superior Accuracy ™ means their precipitation report is 21% more accurate than the next leading weather forecast . 

This app offers a 1-hour visual radar, humidity, dew point, wind, pressure, UV index, cloud cover, and visibility reporting. They also provide a 72-hour detailed forecast with weather, temperature/ real feel and precipitation. Their 15 -day overview forecasts high and low temperatures and likelihood of precipitation. If you enjoy watching the sunrise and sunset or tracking the moon phase, AccuWeather has you covered.

What The Weather

If you love the idea of AccuWeather’s precision, but don’t need quite so much detail, What The Weather is the perfect solution. Using data from AccuWeather, What The Weather presents the forecast using easy-to-understand graphics, bright colors, and colloquial language.The app may warn you of a “thunderstorm late tonight” or tell you to “expect showery weather late Tuesday night.” I also love the comparison to yesterday’s weather; it’s hard to imagine how 20 ° C feels, but knowing today’s temperature is 4 ° higher than yesterday is helpful!

Different tabs offer reports on air quality using AirVisual data including measurements of particulate matter 2.5 and 10, Nitrogen Dioxide, Sulfur Dioxide, Carbon Monoxide and ozone, humidity, wind, precipitation, UV, Cloud cover, dew point, and visibility. 

Plan ahead with a 5-day overview or consult the 12-hour report for details on weather conditions, wind, and temperature.

The Weather Channel

Last, but certainly not least is The Weather Channel app, which is so much more than just weather. The app provides a 17-hour detailed forecast with temperature and conditions with an overview on wind, humidity, pressure, dew point, and UV index Their 6-hour radar forecast helps you visualize future precipitation and plan accordingly. The Weather Channel’s 14-day overview offers high and low temperatures, wind, precipitation forecast for day and night as well as sunrise and sunset times, so you can plan a romantic experience. 

My favorite aspects of this app are the Go Run Index, Allergy Index, Mosquito Index and Dry Skin Index. It’s nice to know whether it’s raining or sunny, but knowing whether I need bug spray or antihistamines is perhaps more important to me than sunscreen and umbrellas.
