Now Japan is in the middle of Tsuyu, which is a Japanese rainy season.
Japanese rainy season is completely different from that in other countries including south-eastern Asian countries.
In above countries, it is said that the rainy season lasts around three months or more, and they often have a violent shower.
It doesn't apply to Japan: Japanese rainy season lasts only about a month, and basically we have not a shower but soft rain all the time.
It is often cloudy when it doesn't rain.
This is why Japanese people don't refer to tsuyu as "a rainy season" even though it is a kind of the rainy season.

In recent years, however, we have sometimes heavy rain which is likely to cause a disaster as the climate is a little weird.
The weather in this year is weird as well.
It seldom rains!
I don't like rain, but it's a quite big deal.
The reason is that if we didn't have much rain in this season, we wouldn't be able to get enough water to get over the hot summer which comes after.
I'm very worried about that. :(
This year, the air temperature is also higher than this season in usual year, so it looks as if it were July.

"Tsuyu" is written as "ume (Japanese apricot) rain" in kanji.
It looks strange because the kanji indicates an ume never be read "tsu".
I tried to search about this, but the reason doesn't seem to be clear.

現在日本は梅雨（つゆ）と呼ばれる雨季の真っ最中です。
日本の雨季は東南アジアの国などの雨季とは全く異なります。
これらの国々では、雨季は3ヶ月程度、もしくはそれ以上続き、スコールがしょっちゅう降るそうです。
これは日本には当てはまりません。日本の雨季は1ヶ月程度のみで、基本的ににわか雨は降らず、弱い雨がしとしとと1日中降っています。
雨が降っていないときは曇っていることが多いです。
このため、梅雨は雨季の一種であるにも関わらず、日本人は梅雨のことを「雨季」とは呼びません。

ただし近年は気候が少しおかしいため、災害を引き起こすような豪雨が降ることが時々あります。
今年の天気も変です。
雨がほとんど降らないのです！
私は雨は嫌いですが、でもこれは大問題です。
この時期に雨がたくさん降らないと、この後やって来る暑い夏を乗り越えるための充分な水を得られないからです。
とても心配しています。(´へ｀;)
今年は平年より気温も高く、まるで7月のようです。

「つゆ」は「梅雨」と漢字で書きます。
「梅」の字は「つ」とは読まないのでこれはちょっと不思議です。
調べてみたのですが、はっきりとした理由はわかっていないようです。
