The biggest typhoon to hit Japan in years is currently wreaking havoc in southern Japan. It’s on course to hit the Tokyo area in a day or two. If you’re in Japan, take care! Typhoon storms, like hurricanes and cyclones, are dangerous!
Teru-teru Bozu
12 MarIt’s not cold in Tokyo today…the temperature is very comfortable. And it’s forecast to stay this warm all week at least.
It’s nice weather today but it’s forecast to rain tomorrow and Friday.
If you have outdoor plans on a day that it’s forecast to rain, what do you do in your country?
In Japan, people (especially children) hang a Teru-Teru-Bozu up.

Do you know what a “Teru-teru-bozu” is?
Teru-Teru-Bozu is a Japanese charm that is supposed to keep rain away.
When Japanese kids have an outdoor event, such as a school “Sports Day” or a field trip, and it’s forecast to rain on that day (and cause the event to be cancelled), they will make a Teru-Teru-Bozu out of cloth or, more commonly, tissue paper and hang it up.
There’s also a song for the Teru-Teru-Bozu that is along the lines of the English song “Rain, Rain, Go Away”.
Actually, I’ve written about Teru-Teru-Bozu once before, five years ago. (Click here to read it.)
Another typhoon
15 OctAnother typhoon is headed for 本州 (mainland Japan).
It’s forecast to hit the 関東地方 (Tokyo area) tonight and tomorrow (Tuesday, 2013 October 15th – Wednesday, October 16th).
Here is a recent meteorological map of Japan. The yellow areas are under a “typhoon advisory” and the orange areas are under a more serious “typhoon warning“.
Tokyo, on this map, is colored orange.
Summer in October
12 OctToday the temperature got up to 31℃. That’s the warmest it’s been in Tokyo in the month of October since records have been kept (since 1885).
It’s forecast to return to “normal” autumn temperatures tomorrow.
Rainy season
28 MayI watch the 天気予報 (weather forecast) on TV every morning.
Today, they said that 梅雨 (rainy season) has officially started in Japan today.
It is starting early this year! Normally rainy season begins in mid-June (I wrote a post about it four years ago. Click here to read it.)
It’s raining in many parts of Japan today…but, thankfully, not in Tokyo.
It is forecast to rain in Tokyo tomorrow though.
Are you in Japan? Are you planning to come soon? Have you ever experienced a rainy season in Japan before?
Tokyo sun shower
4 SepSummer in Tokyo is very hot and humid. There is a typhoon season and sometimes a sudden thunderstorm with heavy rain will start seemingly out of nowhere…and then stop just as suddenly with blue skies returning.
Japanese people are sometimes surprised if I tell them that summer in Florida (where I grew up) is very similar.
Summer in Florida is also hot and humid. There is a hurricane season (hurricanes, for all intents and purposes, are basically the same as typhoons) and sometimes sudden short thunderstorms occur there too.
In fact, the area in Florida where I lived, Tampa Bay, is called “the lightning capital of the world”.
When the weather is sunny and then a rainstorm suddenly starts…with the sunny weather returning just as suddenly, Floridians call that a sun shower.
So I also referred to the same phenomenon in Japan as a sun shower, as well.
But a few years ago, the Japanese media gave these storms an original Japanese name. Here in Japan, these storms are called 「ゲリラ豪雨」 (“Guerrilla rainstorms“) because of the way they violently come out of nowhere.
Well, yesterday, there was a sudden, short, ゲリラ豪雨 (Guerrilla rainstorm)…and someone photographed it from the Tokyo Sky Tree tower.
Winter’s back
7 MarYesterday (Sunday, March 6th) was a nice day and it was pretty warm. My wife and I went to 上野 (Ueno, Tokyo) and walked around (my kids stayed home and studied for their final exams this week).
It was so warm that I began to think that spring has come. But this morning I saw the weather forecast on TV that said it would be a cold and rainy day today…and from about 9:00AM – lunchtime, it would snow!

Tokyo's weather forecast for 2011 March 7 - 14.
The weather forecast was exactly right. It was quite cold today and it snowed all morning starting at about 9:00AM.
I’m happy to see that it’s not forecast to rain or snow anymore for the rest of the week. It’s be sunny most days…and start getting warmer again. Next Monday is forecast to have a high temperature of 16°C (about 61°F).
How’s the weather in your city now?
October weather
10 OctEvery year in October and April, when the seasons are changing, the temperature fluctuates a lot and it rains often.
Tomorrow (Monday) is a holiday in Japan. It’s 「体育の日」 (“Sports Day“). So it’s currently a three-day weekend here.
Yesterday (Saturday), the weather was very cool (high temperature was 19°C) and rainy in Tokyo. Today it was raining in the morning but has stopped raining and it’s cloudy now and warmer (about 23°C).
Tomorrow is forecast to be warm (high temp: 26°C) and sunny.
Next week’s weather in Tokyo is forecast to be sunny most days but rain again next weekend…and the temperature will go up and down.
This fluctuating temperature in early Spring and Autumn is called 「三寒四温」 (“Three days cold, four days warm”) in Japanese.
I was looking at tenki.jp, a Japanese weather website, to get Tokyo’s weather forecast, and I noticed that it’s possible to compare Japan’s weather to any other city in the world using that website.
So I decided to see how Tokyo’s weather compares to Tampa Bay, Florida (where I grew up).
It’s still quite warm in Florida, it seems. Yesterday, for example, was 19°C in Tokyo…but in Tampa, Florida it was 29°C…very warm.
How is the weather where you live?
(By the way, did you notice that today’s date is: ’10-10-10?)
You can balance an egg today
23 SepLast Monday was a holiday in Japan, called 「敬老の日」 (“Respect For The Elderly Day“). On this day, people often give gifts to their elderly parents or grandparents. Many kindergartens invite grandparents to have lunch at the school with their grandchildren.
Today is another holiday in Japan…「秋分の日」 (“Autumn Equinox“). On this day in Japan, and on the 「春分の日」 (“Spring Equinox“) in March, it is common for people to visit their family graves to pay respects. This custom is called 「彼岸の中日」 (“Higan-no-chuu-nichi“).
The actual date of 「春分の日」 (Spring Equinox) and 「秋分の日」 (Autumn Equinox) varies slightly. Spring Equinox is around March 20 or 21 and Autumn Equinox is usually September 22 or 23. I read online that in 1931, the Autumn Equinox occurred on September 24 and the next time it will occur on that date will be in the year 2303.
But in Japan, 「春分の日」 (Spring Equinox) is always celebrated on March 20th and 「秋分の日」 (Autumn Equinox) is always on September 23rd. The only time the dates change is when one of those dates fall on a Sunday…then the holiday is observed the next day.
「敬老の日」 (“Respect For The Elderly Day“) is celebrated on the third Monday of September. Last year that holiday and 「秋分の日」 (Autumn Equinox) were only one day apart, so the Japanese government made the day between them a one-time temporary holiday so that most people in Japan could have a five-day holiday period that was called “Silver Week“.
(I wrote a post about last year’s “Silver Week” here.)
Yesterday someone asked me if the Spring and Autumn Equinoxes were holidays in America like they are in Japan, and how they’re observed in America.
I know that Spring and Autumn Equinox, as well as Summer and Winter Solstice in June and December, aren’t legal holidays in America. But they’re considered the date that the seasons change. Americans say that the first day of Winter is around December 21, the first day of Spring is around March 20, the first day of Summer is around June 21 and the first day of Autumn is around September 23.
So, in America, today is the first day of Autumn.
In Japan, the first day of every three months is considered to be the beginning of the next season.
Winter, Spring, Summer, and Autumn each start on December 1st, March 1st, June 1st and September 1st, respectively.
But maybe the American dates are more accurate. Because yesterday was a very hot and sunny day in Tokyo. It was about 33°C.
But today is a bit cold and rainy. The temperature dropped down to 23°C! And tomorrow is forecast to be even colder…20°C.
Another thing that is said about the equinoxes in America is that they are the only days of the year that you can balance on egg upright.
I don’t know where that came from. But it’s an American urban legend that eggs can be easily balanced on the day of an equinox.
How is Autumn Equinox (and Spring Equinox) celebrated in your country?

Start of Spring
12 AprEvery year at the beginning of spring and again at the beginning of autumn, when the seasons are changing the weather fluctuates from day-to-day.
Yesterday, in Tokyo it was very warm and sunny (22° Celcius (about 72°F)).
But today it’s raining and much cooler. The high temperature in Tokyo today is only 11°C (about 52°F).
And then tomorrow it’s forecast to go back up to 22°C again!
The rest of this week high temperature will range from 10 – 18°C (50-64°F)…and rain some days and it’ll sunny on the others.
Weather in April (and October) is unpredictable.
How’s the weather at this time of year in your part of the world?
