以上(いじょう) ①More than (or equal to), Over・(and) above, Any more・Greater, Exceeding

In order to mark something as 'equal to, or more than (A)', 以上(いじょう) will be used. This is simply a combination of the kanji 以(い) which means 'by means of', and 上(じょう) 'above'. This expression may also be translated as 'greater than (A)', or 'exceeding (A)'.

To use 以上(いじょう), attach it to the amount that you want to highlight as the 'minimum' amount.

以上(いじょう) is also regularly used as a statement that translates roughly as 'the end', or 'that's it', and is a very common way to say that something has finished.

Although saying 'the end' would sound a bit rude in English in this situation, it is completely natural in Japanese, and literally means 'the above (list of things I said) is all'.
