How to say Japanese day of the week

Let’s take a look at some of the ways of saying “days of the week” in Japan.

  • Sunday=日曜日(にちようび、nichiyoubi)
  • Monday=月曜日(げつようび、getsuyoubi)
  • Tuesday=火曜日(かようび、kayoubi)
  • Wednesday=水曜日(すいようび、suiyoubi)
  • Thursday=木曜日(もくようび、mokuyoubi)
  • Friday=金曜日(きんようび、kinyoubi)
  • Saturday=土曜日(どようび、doyoubi)

In English, “Sun” and “Su” are also used, and in many cases, only some of the letters are used in the Japanese language as well.

In some cases, “Sunday” is used, while in other cases, only “Sun” is used.

Therefore, if you remember only the initial letters of “日-月-火-水-木-金-土:にち-げつ-か-すい-もく-きん-ど”, you will not have much trouble at work.

It is better to remember how to say “nichiyoubi” and “getsuyoubi,” of course, but it may also be a good idea to remember just the initial letters in kanji.

1 week” means “one week.

In Japanese, “1 week” is called “1-week (issyuukan).

The week including the day of the week (this week) is called “this week (konsyuu),” the previous week (last week) is called “last week (sensyuu),” and the next week (next week) is called “next week (raisyuu).

In English-speaking countries, “day of week” is used to refer to the entire week without specifying a particular day of the week, while in Japan, “day of the week (youbi)” is used.

And when asking “What day of the week is it today ? and “What day of the week is it today ? You can confirm the day of the week by adding the word “what (nan).

One point to note is that “what” is basically called “nani” in Japan.

In Japan, “what” is basically called “naniga” or “what do you want? (naninisimasuka?)” In many cases, “nani” is used, but there are also cases where it is pronounced “nan” as in “what day of the week”.

In addition to days of the week, “nan” is also used for “how many (nanko)” or “how many times (nankai)” when counting the number of pieces or times.

The week officially begins on Sunday, but Monday is generally the start of the week.

In Japan, as in the U.S. and other countries, the beginning of the week is “Sunday.

In fact, many people in Japan, as in Europe, recognize Monday as the beginning of the week.

The calendar always has Sunday as the leftmost day of the week, and the beginning of the week is always on Sunday.

This is thought to be because the overwhelming majority of people start their work week on Monday.

Weekdays and Weekends

In Japan, the five days of “Monday, Tuesday, Wednesday, Thursday, and Friday (weekdays)” are called “heijitsu” and the two days of “Saturday and Sunday (weekends)” are called “shyuumatsu.

If someone says to you, “Let’s go somewhere for fun on the weekend: shyuumatsu, okay?” means “Let’s go somewhere on Saturday or Sunday.

The phrase “I’m busy on weekdays: heijitsu ” is often used to mean “I’m busy Monday through Friday because I have to work.
