This article will guide you through a fundamental aspect of daily conversations: the days of the week. Mastering these terms will not only help you plan your sushi outings but also immerse you in Japan’s captivating culture.
At first glance, Japanese can appear intimidating due to its three distinct writing systems. However, when it comes to the days of the week, you’ll primarily encounter “kanji” (漢字), the characters borrowed from Chinese. Each day concludes with the suffix “yōbi” (曜日, ようび), similar to how days in English end with “day.” Plus, each day begins with a simple kanji character that’s easy to memorize. Follow this guide, and you’ll master planning your week in Japanese effortlessly!
In this article, discover the names of the days of the week, their fascinating origins, and a variety of related words and phrases that will enhance your understanding.
The days of the week in Japanese
Let’s delve into the fascinating origins of each day of the week in Japanese. Similar to many languages, the names of the days are steeped in astronomy and mythology, tracing back to ancient China. The second character, 曜 (よう, yō), is key to understanding these names, as it translates to “shining body” or “luminary” in Mandarin Chinese. The concept of the “seven luminaries” includes the sun, moon, and five visible planets: Mercury, Venus, Mars, Jupiter, and Saturn. This celestial framework serves as the foundation for the Japanese names of the days.

Sunday: 日曜日 (にちようび, Nichiyōbi)
The character 日 translates to “sun,” which is why 日曜日 is interpreted as “sun day.” This term also has ties to Amaterasu, the sun goddess revered in Shinto belief.
Monday: 月曜日 (げつようび, Getsuyōbi)
月 means “moon, and like many cultures, Japan associates Monday with the moon.
Tuesday: 火曜日 (かようび, Kayōbi)
The character 火 translates to “fire” and symbolizes the planet Mars, historically known as the “Fire Star” in ancient Japanese astronomy. This name captures Mars’ striking red hue, reminiscent of flames.
Wednesday: 水曜日 (すいようび, Suiyōbi)
水 means “water” and refers to Mercury, the “Water Star.”
Thursday: 木曜日 (もくようび, Mokuyōbi)
木 means “wood” or “tree” and refers to Jupiter, the “Wood Star” in ancient astronomy, symbolizing growth and prosperity.
Friday: 金曜日 (きんようび, Kinyōbi)
金 means “gold” or “metal” and refers to Venus, the “Metal Star.”
Saturday: 土曜日 (どようび, Doyōbi)
土 means “earth” and is related to Saturn, known as the “Earth Star.”
Pronunciation
Japanese pronunciation is quite accessible due to its phonetic nature. Each character in the basic alphabets, “hiragana” and “katakana,” corresponds to a specific sound. This means that once you learn to read the characters, you’ll be able to pronounce them accurately.
Unlike languages such as English, where spelling and pronunciation often clash—think of words like “cough,” “pneumonia,” and “what”—this language offers a much more straightforward relationship between the two.
Check out this video that demonstrates how to correctly pronounce the Japanese days of the week. Pay special attention to the elongated ‘o’ sound in 曜日 (ようび, yōbi).
Bonus tips: Dive into ひらがな (hiragana) and カタカナ (katakana) early in your Japanese learning journey. Mastering these two syllabaries will not only enhance your reading skills but also improve your pronunciation of Japanese words.
