If you are visiting Japan, you might want to learn the days of the week (or youbi) in Japanese so you can discuss your flight schedule and travel plans. Even if you are not visiting Japan soon, learning days of the week in Japanese is probably among the initial lessons you will take as a Japanese learner.

Learning the days of the week can be simple for English speakers because each Japanese day ends with the same suffix. It’s -day in English; in Japanese, each day of the weekends with -youbi. Keep this suffix in mind, and you will be halfway there.

How to remember the days of the week in Japanese

If you are just starting out with Japanese, these words may appear intimidating, especially since they are all kanji. The kanji for (-youbi) in particular can be difficult to write by hand, so you might want to start by writing only the first kanji, then -youbi in hiragana.

However, there is a simple memory trick that Japanese students use for the first character of each day of the week. Each day of the week has a natural element that corresponds to its kanji character, and Japanese schools use these mnemonics to help grade students learn the kanji early on. Let’s dissect them together.

Nichiyoubi (Sunday)

The kanji for 日 (nichi) literally means “sun” or “day”. This makes remembering the first day of the week in Japanese especially easy for English speakers. Consider the kanji for “sun” to be a window through which you can see the sunrise on a Sunday.

Getsuyoubi (Monday)

The kanji for 月 (getsu) means “moon” or “month”. Consider Monday rising after a Sunday evening, just as the moon rises after the sun sets.

Kayoubi (Tuesday)

The kanji for 火 (ka) means “fire”. If you use your imagination, the character could even resemble a dancing flame. If you are having trouble visualizing the fire, think of Tuesday as the day you get fired up for the week after a gloomy Monday.

Suiyoubi (Wednesday)

The character 水 (sui) means “water”. You could think of Wednesday as a splash of water to cool off after a hot Tuesday. If that doesn’t help you remember the word suiyoubi, imagine Wednesday as the crest of the week’s wave.

Mokuyoubi (Thursday)

The kanji 木 (moku) means “wood” or “tree”. 木 looks a bit like a bare tree with branches spreading above and below its mighty trunk.

Kinyoubi (Friday)

Everyone looks forward to Friday. The thrill of the weekend is just around the corner. That could be why Kinyoubi’s first character is the kanji for “gold” or “money”: i.e. 金. You can remember this day by imagining all the money you will spend this Friday evening after work, or by thinking, Friday is your favorite day of the week.

Doyoubi (Saturday)

The first kanji character for Saturday is 土 (do), which means “earth” or “soil”. Consider gardening or other relaxing hobbies that people enjoy on their days off to help you remember this. You could also take a literal interpretation of the word “earth” and imagine that on Saturday, the world of possible pleasures is yours to explore.

Learning Japanese is not a difficult process. You need to choose the right learning resources, be consistent and sharpen your imagination.
