By the way, since you’re learning Japanese…

…you NEED to LISTEN to Japanese.

So, here’s a fun audio lesson where you’ll learn some basic words and greetings. Press play and listen below right now.

Days of the Week in Japanese

The good news? All days of the week in Japanese follow a simple pattern.

They all contain “youbi” or “曜日” in Japanese.

If you’re a beginner and if you hear a “youbi,” that’s how you know you heard some day of the week in Japanese.

So, here’s the list of the days of the week in Japanese.

  • Monday – 月曜日 – Getsuyoubi
  • Tuesday – 火曜日 – Kayoubi
  • Wednesday – 水曜日 – Suiyoubi
  • Thursday – 木曜日 – Mokuyoubi
  • Friday – 金曜日 – Kinyoubi
  • Saturday- 土曜日 – Doyoubi
  • Sunday – 日曜日 – Nichiyoubi

Now you know days in Japanese.

As a bonus, here are two more words you need to know. Because the weekend is part of the week too.

  • 土日 – Donichi – Saturday & Sunday (or the weekend)
    • If you’re clever, you’ll notice that “donichi” is just a combination of the first kanji from Saturday (土 – do) and Sunday (日 – nichi).
  • 週末 – Shuumatsu – Weekend

Okay, now you know the days of the week in Japanese.

What’s next? These bonus words.

Bonus Words for Days in Japanese

Like, “today,” “tomorrow” and “the day after tomorrow.”

Here they are.

  • today – 今日 – kyou
  • tomorrow – 明日 – ashita
  • yesterday – 昨日 – kinou
  • the day before yesterday – おととい – ototoi
  • the day after tomorrow – あさって – asatte
  • weekday – 平日 – heijitsu
  • holiday (day off) – 休日 – kyuujitsu
    • Yasumi is also acceptable

    • As in, “someday, I will learn Japanese.”
  • one day – ある日 – aru hi

So now you know the days in Japanese plus some relevant vocabulary.

Now, let’s move onto the days of the month in Japanese.

Days of the Month in Japanese

Counting days in Japanese. Is it as easy as the first, the second or 15th of the month? Well… Not really.

If you already know Japanese numbers

…you’re sort of almost there.

You’re very close to mastering the days of the month.

There are variations that you need to memorize.

For example, the 1st of a month isn’t called “the first” or “ichi” but rather “tsuitachi.” And the 10th of the month doesn’t use “juu” which means “10.” It’s “tooka.”

But when you get to the 10s and 20s, most of them follow an easy formula.

So, take a look below at the Japanese days of the month.

Day Japanese Romaji Day Japanese Romaji Day  Japanese Romaji
1 ついたち Tsuitachi 11 じゅういちにち Juuichi nichi 21 にじゅういちにち nijuuichi nichi
2 ふつか Futsuka 12 じゅうににち juuni nichi 22 にじゅうににち nijuuni nichi
3 みっか Mikka 13 じゅうさんにち juusan nichi 23 にじゅうさんにち nijuusan nichi
4 よっか Yokka 14 じゅうよっか juuyokka 24 にじゅうよっか nijuuyokka
5 いつか Itsuka 15 じゅうごにち juugo nichi 25 にじゅうごにち nijuugo nichi
6 むいか Muika 16 じゅうろくにち juuroku nichi 26 にじゅうろくにち nijuuroku nichi
7 なのか Nanoka 17 じゅうしちにち juushichi nichi 27 にじゅうしちにち nijuushichi nichi
8 ようか Youka 18 じゅうはちにち juuhachi nichi 28 にじゅうはちにち nijuuhachi nichi
9 ここのか Kokonoka 19 じゅうくにち juuku nichi 29 にじゅうくにち nijuuku nichi
10 とおか Tooka 20 はつか hatsuka 30 さんじゅうにち sanjuu nichi
31 さんじゅういちにち sanjuuichi nichi

You will need to memorize the blue ones. Mostly from 1 to 10. But 11 and up are fairly easy.

From 11 and up, most follow this formula:

  • [number in japanese] + [nichi]
  • 11 is juuichi + nichi = juuichi ichi
  • 12 is juuni + nichi = juuni nichi
  • 25 is nijuugo + nichi = nijuugo nichi

The only ones that don’t follow the formula and need memorization are:

  • 14 – juuyokka
  • 20 – hatsuka
  • 24 – nijuuyokka

So, learning the days of the month in Japanese is just a matter of memorization. Or reviewing a lot. It’s not hard. But with enough reviews and glances you’ll get it.

So, print this lesson or save that image I have above.

Now, let’s use the Japanese days of the month in action.

Here are some common phrases to use.

  • Christmas is December 25th.
    • クリスマスは12月25日です。
    • Kurisumasu wa juunigatsu nijuugonichi desu.
  • My birthday is August 21st.
  • It’s April first.
    • 4月です。
    • Shigatsu tsuitachi desu.


Now you know all the days in Japanese. Plus, you know the complicated days of the month too.

If you want to master all of these fun words and phrases, print this page out. Or, copy out the words into a notebook and write them again and again.

That fun stuff really works.
