意味

January. The first month of the year.

Japanese months are numbered rather than named — １月 simply means 'month one.' This makes the system very logical and easy to learn. January holds special significance as the month of New Year (お正月), the most important holiday in Japan.

例文

1. １月１日はお正月です。
2. １月はとても寒いです。
3. 日本では１月に成人式があります。
