一 is the kanji for 1. Learn its shape and use its different readings in words you can actually say.
The idea
一 has 1 stroke. Draw one horizontal stroke from left to right. Read the table aloud: the independent number is いち, but the reading changes with the word. For example, 一月 is いちがつ, while 一日 as a calendar date is ついたち.
| Japanese form | Meaning or situation |
|---|---|
| 一 | number: 1 |
| 一つ | general objects: 1 |
| 一人 | people: 1 |
| 一本 | long objects: 1 |
| 一時 | time: 1 o’clock |
| 一日 | day of the month: 1 |
| 一月 | month: January |
Examples

Watch out
Do not guess every reading from the number alone: 一人 is ひとり and 一本 is いっぽん. Compare the shape of 一 with 二; check the source for stroke order. 一日 can also mean a whole day, read いちにち.
