A simple life hack you can use anywhere in the world.

“What should I wear today?” is a question most people around the world ask themselves each and every morning, and when the seasons begin to change it can become a tough task to answer, especially when pressed for time before the daily commute.

Here in Japan, though, weather reports on TV often provide a wealth of information aside from just the temperature, making it easier for the nation to get themselves properly set up for the day ahead.

Instead of just a forecast for rain, for example, cute icons on the screen will tell you whether you need to have a folding umbrella or a large umbrella on hand, and on other days they’ll let you know exactly how good the day will be for putting laundry outside to dry.

A good day for laundry:

A bad day for laundry:


Another useful piece of advice provided by weather channels is tips on what to wear during the day. And while this information changes daily, Twitter user @hosocoshi came across a handy guide that everyone can find helpful at any time of the year, and it’s a simple one to remember.

The tweet above shows a televised guide with the following information on what to wear, according to the temperature. Starting from the top, we have:

  • 25 degrees Celsius (77 degrees Fahrenheit) and above: A short-sleeved shirt
  • 25 degrees Celsius (77 degrees Fahrenheit) and under: A long-sleeved shirt
  • 20 degrees Celsius (68 degrees Fahrenheit) and under: A cardigan (lightweight)
  • 16 degrees Celsius (60 degrees Fahrenheit) and under: A sweater
  • 12 degrees Celsius (54 degrees Fahrenheit) and under: A trench coat
  • 8 degrees Celsius (46 degrees Fahrenheit) and under: A winter coat

The tweet went viral, receiving over 30,000 likes and 17,000 retweets, with people leaving a wide variety of messages on the subject.

“Thank you for this handy life hack!”
“It’s currently less than 8 degrees in Tohoku so it’s winter coat weather already.”
“This seems to be a good guide for women but as a man I’m fine in a short-sleeved shirt most days.”
“I wear a suit every day so I need to know whether to wear a coat or not.”
“I’m fat so every day is short-sleeved weather.”

While it’s true that every body is different, the large majority of responses were appreciative of the guide. And while this type of information is becoming more widely available with apps these days, Japanese weather site Tenki also provides a “garment index” online every day.

Whether you have access to weather apps or if you’re an older resident without a smartphone, it’s nice to know that weather reports on morning TV shows in Japan create an even playing field by serving up the same type of information you’d get online with handy icons and easy-to-understand guides.

And if you’re really lazy, of course, you can just check out what the weather woman on TV is wearing that day…if she’s not ad-libbing through bloopers with Japanese mascot Gachapin.
