Yo, B!
Looking to learn days in Japanese?
And wondering why I called you “B?” Don’t worry. Just keep “yo b” in mind as you read this guide. In this guide, you’ll learn days in Japanese โ of the week, of the month, and other relevant words.
Here’s a quick preview and I’ll explain it all below.
- Monday – ๆๆๆฅ
- Tuesday – ็ซๆๆฅ
- Wednesday – ๆฐดๆๆฅ
- Thursday – ๆจๆๆฅ
- Friday – ้ๆๆฅ
- Saturday- ๅๆๆฅ
- Sunday – ๆฅๆๆฅ
Let’s go.
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 “ๆๆฅ” in Japanese.
Which sounds like “yo B.” Get it? So, 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 – ๆๆๆฅ – Getsuyoubi
- Tuesdayย – ็ซๆๆฅ – Kayoubi
- Wednesday – ๆฐดๆๆฅ – Suiyoubi
- Thursday – ๆจๆๆฅ – Mokuyoubi
- Friday – ้ๆๆฅ – Kinyoubi
- Saturday– ๅๆๆฅ – Doyoubi
- Sunday – ๆฅๆๆฅ – Nichiyoubi
Now you know days from Monday to Sunday.
As a bonus, here are two more words you need to know. Because the weekend is part of the week too.
- Saturday & Sunday (or the weekend) – ๅๆฅ – Donichi –
- If you’re clever, you’ll notice that “donichi” is just a combination of the first kanji from Saturday (ๅ – do) and Sunday (ๆฅ – nichi).
- Weekend – ้ฑๆซ – Shuumatsu
Okay, now you know the days of the week. What’s next? These bonus words.
Bonus Words for Days in Japanese
Now, aside from Monday and Tuesday, there are other Japanese words you should know.
Like, “today,” “tomorrow” and “the day after tomorrow.”
Here they are.
- today – ไปๆฅ – kyou
- tomorrow –ย ๆๆฅ – ashita
- yesterday –ย ๆจๆฅ – kinou
- the day before yesterday –ย ใใจใจใ – ototoi
- the day after tomorrow –ย ใใใฃใฆ – asatte
- the other day – ๅ ๆฅ – senjitsu
- weekday –ย ๅนณๆฅ – heijitsu

- Yasumi is also acceptable
- day off –ย ไผใฟ – yasumi
- every day –ย ๆฏๆฅ – mainichi
- someday – ใใคใ – itsuka

- one day – ใใๆฅ – aru hi
- As in, “One day, I woke up and decided to learn Japanese.”
- all day – ไธๆฅไธญ – ichnichijuu
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
Now, onto days of the month in Japanese. Is it as easy as the first, the second or 15th of the month?
Well…
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, which I reveal below.
So, take a look below at the Japanese days of the month.
| Day | Japanese | Romaji | Day | Japanese | Romaji | Day | Japanese | Romaji |
| 1 | ใคใใใก | Tsuitachi | 11 | ใใ ใใใกใซใก | Juuichi nichi | 21 | ใซใใ ใใใกใซใก | nijuuichi nichi |
| 2 | ใตใคใ | Futsuka | 12 | ใใ ใใซใซใก | juuni nichi | 22 | ใซใใ ใใซใซใก | nijuuni nichi |
| 3 | ใฟใฃใ | Mikka | 13 | ใใ ใใใใซใก | juusan nichi | 23 | ใซใใ ใใใใซใก | nijuusan nichi |
| 4 | ใใฃใ | Yokka | 14 | ใใ ใใใฃใ | juuyokka | 24 | ใซใใ ใใใฃใ | nijuuyokka |
| 5 | ใใคใ | Itsuka | 15 | ใใ ใใใซใก | juugo nichi | 25 | ใซใใ ใใใซใก | nijuugo nichi |
| 6 | ใใใ | Muika | 16 | ใใ ใใใใซใก | juuroku nichi | 26 | ใซใใ ใใใใซใก | nijuuroku nichi |
| 7 | ใชใฎใ | Nanoka | 17 | ใใ ใใใกใซใก | juushichi nichi | 27 | ใซใใ ใใใกใซใก | nijuushichi nichi |
| 8 | ใใใ | Youka | 18 | ใใ ใใฏใกใซใก | juuhachi nichi | 28 | ใซใใ ใใฏใกใซใก | nijuuhachi nichi |
| 9 | ใใใฎใ | Kokonoka | 19 | ใใ ใใใซใก | juuku nichi | 29 | ใซใใ ใใใซใก | nijuuku nichi |
| 10 | ใจใใ | Tooka | 20 | ใฏใคใ | hatsuka | 30 | ใใใใ ใใซใก | sanjuu nichi |
| 31 | ใใใใ ใใใกใซใก | 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.
