How many times should we knock a door?

Today, I learned how many times we should knock a door.

In Japan, most people think that we should knock a door 2 times anytime.

Essentially, Japanese rooms had been separated by a sliding door made of paper, so we didn't have a custom of knocking.

For this reason, we don't know what the number of knocking means very much.

I also didn't know that until recently.

Generally in the United States and Europe, knocking 2 times means toilet knock, knocking 3 times means close relationship with a person in the room, knocking 4 times means international standard protocol.

Although knocking 3 times is becoming mainstream in the Japanese business scene, nearly 90% of Japanese people knock 2 times yet.

Therefore, if you knocked 3 or more times in Japan, you might seem to be "cool."

But conversely, there is a possibility that you seem to be annoying to knock a door many times.

By the way, the reason for knocking 4 times is derived from Beethoven's Symphony No. 5 "fate."

I heard the beginning of this song represents that the devil is knocking the fate door.

今日は、正しいノックの回数について学びました。

日本では、ドアのノックの回数は、いつでも2回だと思っている人が多いです。

日本は元々、部屋は障子や襖によって仕切られていたため、ノックをする習慣はありませんでした。

このことから、日本ではノックの回数の意味が、あまり定着していません。

私も最近まで、知りませんでした。

欧米では一般的に、2回のノックはトイレの空室確認、3回のノックは親しい間柄の相手に対して、そして、4回のノックは国際標準マナーとされています。

日本のビジネスの現場では、3回ノックが主流になりつつあるようですが、それでも日本人の9割近くは2回ノックをしているようです。

だから、日本で3回以上のノックをすると、「かっこいい」と思われるかもしれません。

しかし逆に、「何度もノックするなんてうるさい奴だ」と思われる恐れもあります。

ちなみに、ノックを4回する理由は、ベートーベンの交響曲第五番「運命」に由来するそうです。

この曲には「ジャジャジャジャーン」という部分がありますが、これは「悪魔が運命の扉をノックする音」だそうですね。

  Usually, for easily-expressed numbers like this, the spelled version is preferred over the arabic numeral. When the number gets more complicated, numerals are fine. No absolute rules, but for example "200,456,832" is better than "two hundred million, four hundred fifty-six thousand, eight hundred thirty-two."
  
  And usually, people will only say something to you about it if the piece of writing is in a more literary context. A post on the internet could use "3" instead of "three" and be perfectly fine. An article in The New Yorker (a literary magazine in the U.S. well-known for its more educated readership and style) would probably always use "three."

Interesting post! To be honest, I've never heard of these nuances in knocking etiquette in my life. I don't think most people in the U.S. or other western countries really give a lot of thought about how many times to knock on a door.

But I'm not surprised that Japan, which is always very concerned about manners, is leading the way in establishing proper manners for knocking!
