The kanji 日 (hi / nichi / jitsu) is one of the most fundamental and frequently used kanji in Japanese. It carries two main meanings: the sun and day.

Originally, 日 was a pictograph representing the shape of the sun - a circle with a dot inside, symbolizing the bright object in the sky. Over time, it developed into the square-shaped character we use today. Because time, dates, and daily life are built around the concept of days, 日 appears everywhere in Japanese: calendars, weekdays, dates, and everyday expressions. It is one of the first kanji Japanese learners encounter and a key building block for understanding more complex characters.

日 is written with 4 strokes and is often found as a component in other kanji related to light, time, and nature. 

Examples of use:
日  (ひ - hi) → sun / day
今日  (きょう – kyō) → today
明日  (あした – ashita ) → tomorrow
昨日  (きのう – kinō) → yesterday
日本  (にほん / にっぽん – Nihon / Nippon) → Japan
日曜日  (にちようび – nichiyōbi) → Sunday
毎日  (まいにち – mainichi) → every day

Fun fact!
The connection between 日 = sun and Japan = 日本 is not accidental! The name 日本 (Nihon/Nippon) means “origin of the sun”, which is why Japan is often called “the Land of the Rising Sun”
