In Japan, there are many typhoon coming every summer~autumn. In fact, by checking the URL below, you can estimate when the typhoon will come.

However, I’m quite sure that it’s a bit hard to read if you’re not a Japanese speaker.

So in this page, I would like to explain how to read the typhoon map in Japan. I’m quite sure that this map is useful.

First of all, a typical typhoon map is like this. Maybe some of you have seen this kind of map before.

Figure 1. Typhoon Map (Japan)

Now let’s see how to read these.

Figure 2. Position of the Typhoon

First, I think you can see two crosses where the orange arrow is pointing at. That is where typhoons locates now. Yes, there are two typhoons in this map.

By the way, when do they mean by “now”?

Figure 3. Information about each typhoon

The answer is over here, the orange arrow of Fig.3. What are there written? Let me translate it into English.

Figure 4. Information about the typhoon

This is the English version of the information board about the typhoon No.14.

If you remember I had previously asked when is “now”, you can see the top right of Fig.4.

For instance, “now” in Fig.3 is 3 P.M. of September 3rd. In japan, special name for each month is not used widely. We just call September 9月(9th month), and February 2月(2nd month).

Figure 5. Typhoon forecast

You now might be able to read the date which the arrow is pointing. It is 3 P.M. in the 5th of September. The kanji 強 means strong, which represents that it is estimated to be still a strong typhoon. 05日(木)15時 means 5th(Thu.) 15 o’clock.

We represent each day of the week by a kanji character according to its Japanese names. Monday, Tuesday, Wednesday, Tuesday, Friday, Saturday, Sunday is represented as 月,火,水,木,金,土,日, respectively.

The black circle next to each date is the estimated area of Typhoon coming.

So to conclude, this black circle means that “Typhoon No.13 is estimated to be somewhere inside the black circle by 3 P.M. of September 5th.”

Figure 6. Strong wind area and Storm area

You’re almost reading this map perfectly! At last, I will explain about this red and yellow circles.

First, the yellow circle is called the “Strong wind area” which obviously means that the wind is bowing hard in areas inside the circle.

The red circle is called the “Storm area.” It means that there are storms inside this circle, and maybe there will be an storm warning issued.

I am pretty sure that you can read the typhoon map now! Some typhoons in Japan are really strong, so please be careful.

Also, if you find this website useful, don’t forget to share it to your friends! Thank you!
